SPECIES ASIATICAE. 197 
Diels intermedia esse videtur ; ab A. ionandra floribus solitariis, 
calyce pilosulo differt. . 
“S.E. Tibet :—At Ka-gwr-pw temple, near the Yunnan 
frontier ; in Alpine turf on precipices. Alt. 15,500 ft. July 
1913.” F.K. Ward. No. 814. 
This appears to be an extreme alpine form of A. napuiligera, 
Franch. The presence of two styles instead of three may, 
however, be a fundamental difference. In his description of 
A. ionandra, Diels * points out that his species is closely related 
to A. napuligera, differing in the glabrous sepals and two styles. 
Further material from Yunnan tends to bridge the gap between 
the two species. Thus in Forrest No. 6192 the two species appear 
on the same sheet, collected together in the Lichiang Range. 
I find a transition in the hairiness of the calyx and in the number 
of styles. Specimens with solitary flowers occur in the same 
gathering. 
g001 Arenaria oresbia, W. W.5m. Sp. nov. 
Species inter himalaicas et chinenses affines bene distincta ; 
quoad habitum foliaque haud remota ab 4. lichiangenst, W. W. 
Sm. a qua pedunculis elongatis foliatis atque floribus multo 
majoribus longe recedit. 
Planta densissime pulvinata glebam 7-8 cm. diametro 
formans. Caudex lignosus polycephalus, foliorum reliquiis 
densissime indutus. Cauliculorum sterilium pars viridis brevis- 
sima, pars hypogaea praelonga foliis emarcidis induta; caules 
floriferi ad 10 cm. longi erecti flexuosi foliorum paribus 3-4 
remotis muniti, plus minusve dense fulvido-pubescentes. Folia 
basalia dense conferta, 10-15 mm. longa, I-I.5 mm. lata, linearia, 
pungentia, rigida, glabra, margine albido-marginata et indurata 
et minute asperulata ; folia caulina inferiora basalibus similia, 
superiora circ. 1 cm. longa, dorso pubescentia, margine molliter 
et dense ciliata. Flores solitarii albi subnutantes ; pedicelli 
circ. 1 cm. longi dense fulvido-pubescentes. Calyx basi rotun- 
datus vix incrassatus; sepala 6—7 mm. longa, 3-5 mm. lata, 
ovata vel ovato-lanceolata, apice rotundata, pubescentia et 
margine dense atque molliter ciliata, ultimo subglabra vel 
glabra. Petala 13-15 mm. longa, late obovata, vulgo integra. 
Stamina 10 calycem aequantia glandulis alternantia. Ovarium 
ovoideum subnitens stylis tribus brevibus coronatum. Capsula 
matura calycem paulo superans , semina desunt.
