382 PROCEEDINGS OF THE AMERICAN ACADEMY 



142. Rubus macropetalus Dougl. in Hook. 1. c. t. 59. 



143. Rosa gymnocarpa Nutt. in Torr. & Gray, 1. c. p. 461. 



144. Rosa blanda Ait. ? Chiefly, at least the fruiting specimens, 

 of the form (if such it be) answering to R. Woodsii Lindl. Ros. & Bot. 

 Reg. t. 976. Fruit subdepressed-globose, with no neck at all; until 

 full-grown with the calyx-lobes spreading, then apparently ascending 

 or erect. R. fraxinifolia of Watson in King's Exploration is the same 

 with larger fruit. — A small quantity, insufficient for distribution, was 

 collected, of a common Nevadan and Californian Rose, Mr. Watson's 

 R. blanda. This has smaller flowers, stipular prickles when present 

 inclined to curve, the calyx-tube with a contracted neck, and an ovoid- 

 globular fruit, about 5 lines long when full grown, the persistent calyx- 

 lobes tardily ascending or at length conniving. I do not know this in 

 North-eastern America, to which R. blanda proper belongs. I take 

 it to be Chamisso and Schlechtendal's R. Galifornica. 



145. Rosa pisocarpa, n. sp. Gracilis, aut inermis aut aculeis 

 substipularibus acicularibus tenuibus rectis nunc paucisque minimis 

 petiolaribus munitis ; corymbo pauci-plurifloro bracteoso ; calycis lobis 

 (extus glandulosis intus cano-tomentosis) e basi ovata in acumen saepius 

 gracile sursumque lanceolato-dilatatum productis, tubo glabro primum 

 urceolato, fructifero fere globoso (pisi magnitudine) basibus tantum 

 loborum persistentibus arete reflexis coronato ; pedunculis fructiferis 

 nutantibus ; — cast, prascedentis vel R. blandce forma minoris. Petala 

 laete rosea, obcordata, lin. 6-8 longa. Foliola semipollicaria ad polli- 

 caria. 



146. Rosa Kamtschatica Vent. Cels. t. 67. In fruit only ; the 

 strong shoots densely setose, and with immense dilated aculei. One or 

 two smooth specimens also collected. An intermediate form is in Dr. 

 Lyall's collection, from Vancouver's Island. The R. cinnamonea in 

 PI. Hartweg, to which Ventenat's plant is referred as a synonyme, 

 is wholly different, and apparently R. Galifornica, Cham. & Schlecht. 



147. Pyrus rivularis Dougl.; Hook. Fl. Bor.-Am. t. 68. 



148. Ptrus (Sorbus) sambucifolia Cham. & Schlecht. In 

 fruit. 



149. Amelanchier Canadensis var. alnifolia Torr. & Gray, 

 Fl. 1, p. 473. In fruit. 



150. Saxifraga integrifolia Hook. Fl. Bor.-Am. 1, p. 249, 

 t. 86. 



151. Saxifraga Virginiensis Michx. ; a very tall form.
