As I have not seen any authenticated specimens of Harvey's 

 Lept peetia, I cannot be quite sure whether this is the plaat 

 described by him, or not. However, there cannot be the slightest 

 doubt about its being a true Pentopetia. The only noteworthy 

 difference between our plant and the Mascarene species of Pento- 

 petia lies in the very short tube of the corolla, and the glabrous 

 appendices of the anthers. Although the flowers of the present 

 species are not showy, being but small and of a light green colour, 

 it is well worthy of being introduced in the greenhouses of Europe, 

 for its fine dark leaves make it a really handsome plant. 



2. Gomphoearpus ( § Krebsia) stenoglossus, n. sp. Glaber- 

 rimus, e basi ramosus, ad 20 cm. altus; ramis erectis, dense foliatis; 

 foliis erectis angustissime linearibus acutis, marginibus haud revo- 

 lutis, basi in petiolum brevissimum angustatis, 2-4 cm. longis, 

 internodia superantibus ; floribus in fasciculis subglobosis, extra- 

 axillaribus, alternantibus, plurifloris, pedicellis filiformibus glaber- 

 rimis, floribus subduplo longioribus ; calycis segmentis lanceolatis
