K. P. Jones, Barrington, Rhode Island. Wichuraiana Hybrids.
This strong, clean growth is typical of most of the Brownell roses; they need more breathing space than the more tender hybrid teas. ‘Pink Princess’ and 'V for Victory' can be grown to five- or six-foot plants and their blooms are the equal of most at their tender rivals but they need to be spaced no closer than four feet apart to grow properly.

p158.  H. R. Rosen.  Search for Black-Spot Resistance in Roses.
The Brownells' variety referred to is Pink Princess.  Since this represents a definite landmark in rose-breeding, it is worth while to analyze this variety carefully.  It appears necessary to note that of the numerous reports of resistance to black-spot in "everblooming" bush varieties, this is apparently the first one to possess real resistance.  (Whenever authoritative reference has been found to such varieties possessing black-spot resistance, the writer has tested them and up to the present, not a single one has shown resistance other than 'Pink Princess').  It is not completely immune.  The parentage of 'Pink Princess' is given as (Dr. W. Van Fleet x Gen. Jacqueminot) x Break o'Day.  The parentage of the latter is given as Seedling x Glenn Dale.  'Pink Princess' is therefore heavily weighted by Wichuraiana "blood" from both the maternal and paternal parents, a fact which may explain not only black-spot resistance but also a high degree of freedom from winter injury.

Pink Princess: Canes much too willowy and flop to the ground with the weight of blooms, which are of an ordinary type of pink. I do not intend to keep it.

Mr. S. J. Bisdee. Tasmanian Roses
I tried out three of Brownell's "sub-Zero" strain - Anne Vanderbilt, Break o' Day and Pink Princess. The foliage of all three is exceptionally clean and healthy and very like that of Mr. Clark's Mariorie Palmer.
Pink Princess: Good growth; shapely deep pink bloom of a rather uninteresting shade which did not excite me at all.

Also [Mr. Brownell's}  newer varieties, especially Pink Princess are much more resistant to black-spot and mildew, and they do bloom much more freely here throughout the summer and fall than do any of the roses except the Polyanthas.  These roses were given a very severe test last winter.  Six each of ....and Pink Princess were planted in the 1938 fall, merely covering them with soil.  

p88-4  ibid.  Pink Princess does not seem to be damaged at all by black-spot, no matter how much it is exposed.

p64. R. Marion Hatton.  New Roses in America. 
Offered as a sub-zero Rose, Brownells' Pink Princess is worth trying under various conditions. The plant is sturdy and really works at blooming, producing quite nice fragrant flowers of clear pink. Good reports are coming in from widely separated sections, and it is worth trying in your difficult regions. Its parentage (Dr. Van Fleet x General Jacqueminot) x Break o'Day, provides an interesting background.

p113.  Mr. Allen A. Brundrett.  The New Importations of 1940.
Pink Princess, Anne Vanderbilt and Break o' Day are three H.T. varieties raised by Brownell, of Rhode Island, U.S.A., and represent a new and very welcome break in constitution and habit, possessing what the Americans call " sub-zero hardiness." All three are fragrant, produced on very long stems, and should make excellent garden Roses. Pink Princess is first choice in this trio, being bright deep rose pink. The flowers are very double and the bud very firm.
