SPECIES CHINENSES. 199 
obtecta, nervis supra impressis subtus paulo elevatis. Inflore- 
scentiae plerumque I-3-florae; pedunculi ad 8 cm. longi; 
flores 1.5-2 cm. lati. Calyx longiuscule dense incano-villosus ; 
sepala exteriora circ. 8 mm. longa interioribus plerumque 
longiora, ambitu obovata vel ovata in lobos lineares vel lineari- 
lanceolatos profunde 3-(rarius 4—5)-fida, exteriora 6-7 mm. 
longa, lanceolata, acuta. Petala circ. 1 cm. longa, late obovata 
flava. Stamina 20 filamentis brevibus; annulus staminifer 
glaber disco angusto albo-piloso a receptaculo separatus. Car- 
pella numerosa receptaculo albo-piloso inserta ovoidea levia 
circ. 0.5 mm. longa; stylus primo basi vix incrassatus, sed in 
maturo fructu certe ad Conostylas spectat, circ. 2 mm. longus ; 
carpella matura circ. 1 mm. longa, stylo duplo breviora. 
Only known in cultivation in the Royal Botanic Garden, 
Edinburgh, but almost certainly from the province of Yunnan, 
China. It was found among seedlings of Chinese species, the 
parent plants of which were collected by George Forrest. It is 
not, however, represented among the Potentillas of Mr. Forrest’s 
Chinese ‘collections. Potentilla nivea, Linn., is not recorded 
from Southern China and does not appear in the recent collec- 
tions of Mr. Forrest. Potentilla mnivea, Linn., var. elongata, 
Th. Wolf, a Central Asiatic and Mongolian plant, comes nearest 
to the new species. None of the Himalayan forms approach 
the Yunnan plant. Owing to the characteristic calyx and long 
style, I have separated it from P. nivea, Linn., though with 
hesitation in view of the polymorphic nature of that species. 
In the description I have followed closely the sequence of Dr. 
Wolf, so that comparison of the two species can easily be made.
