itffi^* Oxyria sinensis, Hemsl. (Plate XXXIII.) 



Ab O. digyna differt caule folioso inflorescentiae magis divaricatis 

 fructu latiore quam longo stigmatibus sessilibus. 



Herba, ut videtur, perennis, erecta, circiter bipedalis, caule 

 valido striato hispidulo infra inflorescentiam simplici. Folia 

 radicalia non visa, caulina distincte petiolata, crassa, subcarnosa, 

 opaca, rotundato-cordata vel fere reniformia, l|-2 poll, lata, 

 glabra, undulata simul minutissime crispata, interdum obscure 

 lobulata, venis paucis inconspicuis ; petiolus 1-2 poll, longus, 

 basi in ochream latam tubulosam truncatam expansus. Flores 

 hermaphroditi, racemoso-paniculati, fasciculati pedicellis capil- 

 laribus 2-3 lineas longis ; panicula densa, circiter 9 poll, longa, 

 bis terque ramosa, hispidula, bracteis minutissimis. Perianthium 

 minutum, fructiferum vix auctum, segmentis 2 exterioribus 

 demum reflexis, 2 interioribus majoribus oblongis nucem arete 

 appressis ; stamina 6 quam perianthium fere dimidio breviora. 

 Nux late bialata.

It is worthy of note that the very widely spread Oxyria digyna, 

 Hill, the only other known species of the genus, has not hitherto 

 been found either in China proper or Japan ; yet it occurs in 

 the mountains of Northern India and in the island of S; 

 It is also spread all round the arctic regions and extends south- 

 ward in the mountain-ranges of both eastern and western North 

 America, to the Pyrenees and Alps in Europe, and to the 

 mountains of Syria in Western Asia.
