THE CARYOPHYLLACEZ OF TIBET. 399 
is somewhat obscure. The material (fragmentary scraps on a single sheet) 
is so scrappy that the vague description given by no means identifies the 
* type-specimens." The description seems to indicate a plant quite glabrous, 
with short stems and solitary flowers, and leaves thickened though not 
exactly fleshy, and narrower in proportion than those of other species in the 
section Sikkimenses ; and more resembling the Persian A. bulica rather than 
any Himalayan species. It is certainly doubtful whether the specimens here 
referred to A. Stracheyi really belong to this species, but they resemble the 
plant more than they do any of the other specimens of Arenaria in the Kew 
Herbarium ; and A. Stracheyt is recorded for Tibet. 
15. ARENARIA RAMELLATA, sp. п. (Subg. Euarenaria, sect. Sikkimenses.) 
Nana, glabra. Caules 4—6 cm., divarieato-adscendentes ramosi, ramis 
divergentibus, foliosi. Folia 8-9 mm., usque ad flores numerosa, lanceolata 
acuta sessilia firma plana, nervis obscuris, basin versus attenuata, et ibidem 
interdum margine ciliata, ceterum glabra; folia pedicellaria haud bractei- 
formia sed aiiis consimilia, Flores ad ramos laxe cymosos solitarii, pedicellis 
longiores. Calyx campanulatus, basi attenuatus; sepala lanceolata acuminata, 
apice recurva, anguste membranaceo-marginata. Petala alba obovata, calyce 
sesquilongiora, apice rotundata, basi vix unguiculata. 
Karoo-la, 15 miles from Lhassa, 1878 (Dungboo, n. 1158). 
Very near A. Stracheyi, but differing both from the type-specimens and 
also from Edgeworth’s description, Readily distinguished from the next 
species, to which it is closely allied. 
16. ARENARIA MELANDRYIFORMIS, sp. п. (Ejusdem sect.) 
A specie sequente diversa: caules altiores, 10-15 em., magis foliati. 
Folia basalia spathulato-linearia sepe fasciculata, caulina lanceolata acuta. 
Sepala anguste lanceolata, vix obtusa, obscure trinervia. Petala obovata, 
calyce duplo longiora. 
a. Forma glanduloso-pubescens. 
Beong-chin, a mountain west of Chumbi in Tibet Himalaya, 1882 (King's 
collector, n. 1121). 
b. Forma magis hirsuta. 
Syam-poo, in Chumbi district, Tibet Himalaya, 1884 (King's collector, 
n. 123). 
17. ARENARIA MELANDRYOIDES, Ldgew. 
Syam-poo, in Chumbi district, 1884 (King's collector, n. 129); Rungkia, 
in Chumbi district, 1879 (ungboo, n. 1122); Naku Pass, 1903 (Col. Young- 
husband, n. 169). 
These agree with specimens in Herb. Kew. from Yatung in Tibet (И. Е. 
Hobson, 1897), overlooked in Mr. Hemsley's “ Flora * (p. 170).
