Willk. & Lange, Prodr. Fl. Hisp. iii. p. 619. 
De Candolle says that in the authentie specimens he examined 
(Prodr. i. p. 413) the capsule had only five valves after dehis- 
cence; but J. Gay, who examined similar authentic specimens, 
traverses this statement. What is certain is that in Schimper's 
authentic specimens from the locus classicus, the capsule is deeply 
6-valved, and there are remains of three styles distinct at the 
base. Boissier’s Spanish specimens are those which seem to 
most nearly agree with the type-specimens, labelled Stellaria 
Arenaria, in Linneus’s own herbarium.

Dense pulvinato-cespitosa. Caudicis rami lignosi plus minus 
abbreviati. Folia fere navicularia, supra glabra, subtus villosa, 
margine ciliata. Flores 3-5-conglomerati, foliis supremis involu- 
cati. Sepala ovata, margine villosa. Petala nulla. 
I know of no other reference to this plant than that given 
above. The short description is scarcely more than sufficient to 
determine its position in the genus, and the damaged specimens 
are too fragmentary to add much more. 
Hab. Bolivia (Mandon, no. 961). 
b. Folia angusta acuminata. Sepala acuta.
