Camp XII, 10,500 ft. 



The most shrubby of any Pilea I have seen, the habit being that of one of the small 

 Vaccinia with quite woody stems and branches and densely crowded thick fleshy 

 coriaceous leaves. 



Pilea thtmifolia, Ridl., sp. nov. 



Fruticulus repens, ramis tenuibus vix 1 mm. crassis nodosis. Folia congesta, opposita, 

 crasse carno-coriacea, oblonga, 2 mm. longa, obtusa, sessilia, cystolithis plurimis 

 radiantibus, costa subtus depressa superne obscura. Stipulce 2, minutse, membra- 

 nacese, rufescentes, lanceolattTe, denticulatye. Flores masculi singuli, axillares, 

 subglobosi, 2 mm. longi, pedicellis 0*15 mm. longis. Sepala 4, ad basin connata, 

 obtusa, crassiuscula. Stamina 4, filamentis linearibus longioribus, antheris ovatis 

 cordatis. Pistillodium minutissimum, conicum. Flores feminei desunt. 

 Camps XIII to XIV, 10,500 to 12,500 ft. 



This small shrubby creeping species differs from P. alpestris in the much smaller 

 leaves and stems and rather larger flowers. The leaves possess large numbers of cysto- 

 liths, all arranged in a radiating manner, pointing from the base towards the apex along 

 the edge of the leaf at the tip, and occasionally irregularly scattered ; on the underside 

 are circular black depressions. (There are traces of these in P. alpestris.) 



These three species P. helxinoides, P. alpestris, and P. thymifolia, with P. Jolmiana, 

 Stapf, might possibly constitute a distinct genus. The plants seem to be always 

 unisexual, and the male flowers always solitary with the parts in fours.
