C. Hookeri, Dcne, in Nouv. Archiv. du Mus., Ser. 2, vol. iv. p. 206, t. 11.

The Clematises of the tubulosa group are likely to prove a trouble to horticulturists anxious to keep a correctly named collection of these beautiful plants ; and I fear that the efforts of my late friend M. Decaisne to divide them (in the work quoted above) into species will not prove to be altogether satisfactory. Only one form of the group has hitherto been figured in this work, namely, that called C. tubulosa, Plate 4269, and this Decaisne separates from C. tubulosa, as C. Hookeri ; fortunately he gives an admirable plate of C. Hookeri, which precisely accords with the figure here given ; whereas the C. tubulosa of Plate 4269 as exactly (except in the obtuse anthers) accords with his C. Davidiana (p. 205, tab. 10), also excellently well figured by him, and differing from Hookeri in the much shorter pedicels, more crowded axillary erect flowers, and more spathulate sepals which are revolute from the middle, and the very acuminate anthers (not shown in the Botanical Magazine figure of tubulosa). Whether Davidiana is separable specifically from tubulosa is another question. M. Maximovicz, whose knowledge and acuteness as a systematist are of the highest order, regards all Decaisne's eight species as forms of one polymorphous plant (" Melange Biologique," in Bull. Acad. St. Petersb. vol. ix. (1876), p. 589); and judging from the published figures, I should think he is right. If there is a second species, it is probably C. Davidiana, as to which being different the reader may judge by comparing the present plate with 4269, and I may add that the habit of the two in the garden is not the same. Then again with regard to var. Hookeri, the figure of it given by Decaisne precisely accords with that given as the typical tubulosa ; — if the names were transposed, no one could tell the difference. In the text they are separated by the stems being herbaceous and annual in the latter, and woody at the base in the former ; to which he adds that Hooheri is the most precocious of the group, flowering (in Paris, I presume) at the end of February (at Kew in September !). Lastly, there is a C. azurea, Lindl., stated to be from the Crimea (the Tauride), of which Decaisne says that it probably is C. Hookeriana (tubulosa, Botanical Magazine), adding that the Tauride is given in the Botanical Magazine as the native country of its tubulosa. This is a curious oversight, for in that work North China is given as the habitat, and there is no allusion to the Crimea.
There is another branch of this group of the tubulose Clematises which inhabits China and Japan, and of which C. stans, Sieb. and Zucc, is the type; these have smaller more crowded flowers of an opaline colour rather than lilac, and usually more acuminate sepals. C. stans has flowered at Kew, and will shortly be figured ; by which time I hope that the genus will have been revised by Messrs. Forbes and Hemsley for a census of the plants of China which is in preparation at Kew.
The specimen here figured is from an authentically named plant of C. Hookeri sent to Kew by my late friend M. Lavallée; it flowered in the open air in the end of September. — J. B. H.

Le Clematis Davidiana a ete obtenu en 1864 de graines envoyées de Chine au Muséum par M. l'abbé David. L'espèce est franchement dioïque, car, depuis sa premiere floraison, elle n'a jamais produit de pistils, et, chose remarquable, tous les échantillons d'herbier, envoyés de Pékin par M. le D^r Bretschneider, nous ont offert le meme caractère. Ses tiges sont annuelles et ne laissent aucune trace à la surface du sol pendant l'hiver. Sa végétation commence à se manifester vers le mois d'avril ; ses tiges, a peu près cylindriques, s'élevent au plus à quarante centimètres; leur surface est couverte de
poils blancs soyeux ou veloutés. Les feuilles inférieures sont portées sur de très-longs pétioles, faiblement canaliculés en dessus, de la grosseur d'une plume de corbeau, couverts de poils semblables à ceux de la tige, et fortement teintés de violet a leur insertion. Le limbe des feuilles radicales se partage en trois lobes plus ou moins orbiculaires, bordés de grosses dents mucronées; les nervures primaires naissent é environ un centimètre au-dessus de la base du limbe et vont en se rapprochent du smmet; le limbes des feuilles caulinaires est, au contraire, elliptique ou obovale, attenue ou cuneiforme à la base, très-courtement pétiolulé, et à peu près glabre.
Les fleurs, d'un beau bleu indigo, naissent en petites cymes de 7 fleurs, à peu près sessiles, soit au sommet des rameaux, soit aux aisselles des feuilles; le périanthe, soyeux en dehors, très-glabre en dedans, se compose de quatre folioles a prefloraison valvaire, légèrement indupliquées, linéaires ou linéaires-spathulées, épaissies au centre, minces et ondulées sur les bords. Les étamines, au nombre de 14 ou de 16, se composent d'un filet linéaire blanc et glabre terminé par une anthère linéaire apiculée. Le centre de la fleur ne presente aucune trace d'organes femelles.
Cette espèce repand, en herbier, une odeur tres-prononcée d'acide benzoïque ou de fève tonka, que je n'ai sentie sur aucune autre du groupe. Elle fleurit en juillet.

p. 280: Clematis tubulosa, Turcz.
C. herbacea, repens, monoica; caulibus 6-angulatis, glabriusculis, violaceo tinctis; foliis trilobatis, petiolis longis, gracilibusque, segm. terminalibus suborbicularibus breviter acuminatis v. sublobulatis dentatis, dentibus mucronulatis; iferiribus subsessilibus ovatis v. subdeltoides inæquilateris glabris v. puberulis trisectis, segmentis rhomboideis; floribus intense cæruleis; pedicellis reflexis, gracilibus, subincanis; fructibus parvis, hispidulis, oleosis.

Le Clematis tubulosa, décrit et figuré par Lindley, est une plante à rhizome rampant et souterrain de la grosseur d'une forte plume. Ses tiges herbacées, annuelles, glabres et qui s'élevent a environ 40 centimètres, portent des feuilles minces, 3-foliolées ou simplement trilobées, à petiole commun très-grêle et souvent de 14 à 16 centimètres de longueur. Le limbe de la division terminale est ordinairement orbiculaire, légèrement acuminé au sommet et un peu atténué à la base, rarement lobulé, bordé de grosses dents terminées par un mucron cartilagineux ; les nervures primares naissent un peu au-dessus de la base du limbe ; celui des divisions inférieures est ovale ou deltoïde, inéquilatéral ; mais il arrive souvent que les feuilles de l'extrémité supérieure du rameau sont simplement trilobées; dans ce cas le lobe moyen est obovale, les deux lateraux ovales et horizontaux ; le pétiole commun ainsi que les pétiolules sont d'un bleu d'indigo, canaliculés en dessus et, sur ce point, de couleur violette ou vineuse. Les fleurs pédicellées et réfléchies naissent soit a l'aisselle de petites bractées, soit a l'extrémité d'un pédicelle cylindrique dressé faisant partie d'une cyme triflore, et qui, dans ce cas, appartient a une fleur femelle. Les sépales lineaires, acuminés, étroits, d'abord dressés, puis recourbés apres l'anthèse, sont à peine incanes en dehors. Les étamines, au nombre de 14 à 16, sont munies d'un filet linéaire, glabre, terminé par une anthère linéaire, apiculée a connectif fort etroit. Les pistils, très-soyeux, se terminent par un stigmate blanc, papilleux, assez épais. Les fruits, couverts de poils blancs, raides, dressés, avant leur parfaite maturité, sont de couleur olivâtre; plus tard ils prennent une teinte roussâtre et se terminent par queue plumeuse d'un centimètre environ de longuer. La plante fleurit en septembre.

Clematis (Flammula) tubulosa, TURCZ. HANCE in The Journ. of Linn. Soc., XIII, p. 75, 1873.
"I have little doubt that Dr Williams's plant, which he describes as « a coarse vigorous annual, with rank-smelling purple flowers " is referable to this species, only known to me, however, from Walpers's Repertorium . . In the Peking specimens, the lower leaves are trisected, the upper trilobed only, or merely irregularly slashed, usually sparsely hairy, and prominently reticulate; the cohesion of the sepals, through evident, is very slight, and at full anthesis they become free to the base; the anther is scarcely longer than the filament; and the flowers are apparently polygamous; for in the same corymb I find both staminal flowers, and pedicels from which the calyx has fallen, surmounted by the plumose ovaria.
... I have also, gathered by Dr Williams, a plant with hermaphrodite blossoms, solitary and long-stalked, or arranged in a few-flowered raceme, each flower borne on a pedicel an inch or more in length; but the foliage and calyx are so similar that I do not doubt its being a mere variety of Cl. tubulosa. This approaches somewhat to the rare Cl. stans, S. and Z. which is unquestionably the nearest ally of Turczaninow's species; but in that the flowers (which are doubtless also polygamous, not strongly diœcious) are more than twice as small, shortstalked, and arranged in 2-3 distant clusters, forming a raceme. As the sections are limited in the Flora indica, Cl. tubulosa would, from its inflorescence, fall rather into Cheiropsis; but its affinities are against such a collocation. »

p. 147: C. TUBULOSA, Turczaninow. [Plate XVII.]— A stout growing herbaceous perennial, with stiff erect slightly branched stems, somewhat woody at the base, bear ing large long-stalked ternate bright-green leaves, the leaflets of which are rhombeo-ovate and mu cronately -toothed, the middle one being largest. The flowers are numerous, in terminal and axillary corymbs, and individually bear considerable resem blance to those of a single blue hyacinth ; they, how ever, consist of four distinct sepals recurved at the top, and so closely convergent for the greater part of their length that the blossoms appear tubular ; the colour is a bluish -purple, and they are freely pro duced in August and September. A coloured figure, not very characteristic, is given in the Botanical Magazine (t. 4269) ; that in Paxton's Magazine of Botany (xiv. , 31 ) is better. An excellent wood -cut figure, here reproduced through the courtesy of the editors of the Journal of Horticulture, was published in the Journal of the Horticultural Society (iii . , 19) . The plant is a native of the North of China and Mongolia, and has sometimes been called C. mongolica.
