22. ARENARIA MONANTHA, sp. п. (Subg. Eremogoneastrum, sect. ii.) 
Nana, uniflora, stricta, 5-6 cm. Caulis inferne bifariam pubescens, 
superne breviter et retrorsum pilosus, simplex. Folia 8 mm., elliptico-linearia 
acuta subenervia, supra glabra, subtus puberula, margine parce ciliolata. 
Flos longe pedunculatus ; peduneulus basi sepe foliis 4 approximatis 
instructus. Calyx basi truncatus, aperte campanulatus ; sepala ima basi 
connata, pilosa elliptica vix acuta, alternatim anguste lateque scarioso- 
marginata, obscure nervata. Petala integra ovata alba, basi breviter un- 
guiculata, longitudinaliter evidenter striata, calyce sesqui-duplo longiora. 
Glandul» luteo-virentes prominentes, staminibus alternantes. 
Not unlike a dwarf and depauperate form of A. Griffithi, but leaves not 
rigid. There is already an “ Arenaria uniflora” from the island of Kurre- 
Saar in the Gulf of Riga, though, indeed, it is a doubtful species. Otherwise 
this name would have been adopted for the present species, in accordance 
with the Latin form of the generie name.
