106 SPICILEGTA FLOE.^ SINENSIS. 



14. husa microcarpa, LintU. Juxta Fiichaii, Maio 1873, coll. 

 filius Alfredus ; circa Cliinkiang, a. 1876, Stronach. Prof. CrexDin, 

 who has shown that my R. amoyensis is identical with this, remarks 

 ('Prim. Monogr. Kosac.,' 3e fasc. 246): — '' M. Hance, en le 

 decrivant n'a pas meme songe a le rapprocher dn JR. microcarpa, 

 Lindl. ; il I'a range dans la section des Xobiles.'' In reference to 

 this observation, I may take leave to state that I make no preten- 

 sion to have mastered the views of recent rhodologists, amongst 

 whom M. Crepin holds so high a rank ; nor, mdeed, are the most 

 renowned experts as yet sufficiently in accord, to enable an 

 ordinary student to see his way very confidently in this difficult 

 study. When I placed my supposed new plant amongst the 

 Nobiles, I understood the group as defined by Koch (' Synops. Fl. 

 Germ.,' ed. 3, i., 199), who distinguishes it by its ovaries being 

 sessile within the calyx-tube, and who does not recognise the 

 Systylcb as a distinct section, but distributes them between his 

 Canina and Xobiles. With this explanation, it will be found that 

 R. vn'crocarpa really belongs where I had stationed it, though the 

 profounder studies of specialists have greatly modified the older 

 classification of Roses. 



15. Saxifraga (Hirculus) serpiUifoUa, Pursh, var. Pallasiana, 

 Engl. In m. Siao Wu-tai-shan, Chinae bor. Jul. 1876, leg. 

 Hancock. 



This distinct variety, which diflers from the typical form 

 ** viscositate foHorum, caule glandulis rarioribus obsito, floribus 

 majoribus " (Trautv. Florul. Taimyr.,' Phanerog. 42), had only 

 previously been met with, as an Asiatic plant, in Arctic Siberia, 

 and doubtfully near Lake Baikal. It is placed by Torrey and 

 Gray (' Flor. N. Amer.,' i. 566) in the section Aizoonia, and 

 by Engler (' Monogr. d. Gatt. Saxifraga,' 209) in Trachyphyllum. 

 Drs. Hooker and Thomson (' Journ. Linn. Soc.,' ii., 71) station 

 its near allies, S. perpusilla and S. Stella-anrea, in Hircuhis, which 

 may, I think, well absorb all or nearly all the Trachyphylla : 

 indeed, in his ' Index Criticus Spec. Gen. Saxifragae,' Engler 

 placed S. serpiUifolia under Trachyphyllum, but the Himalayan 

 species just mentioned under Hirculus. It is a very interesting 

 addition to the Chinese Flora. Trautvetter's plate (' Imag. PL 

 Ross.,' t. 81) is a very faithful one. 



16. Parnassia oreophila, sp. nuv. Robusta, 10-pollicaris, radice 

 fibrosa, foliis membranaceis radicalibus petiolo laminam paulo
