 wall, near the waterfall, and at the summit of Lanaihale, young plants only,

This species is very closely related to C. atra and may be only a form of 

 the latter. The writer is not ac(iuaHited with the mature plants, having only 

 collected and observed two young specimens. The type in the Berlin Herbarium 

 has flower buds only.

There is no specimen of tiiis species in Hillebrand 's collection in the Berlin 

 Herbarium. One sheet marked Ctiaiua afra in the above herl)arium is ('i/aiua 

 macrosfffiia Ilillebraud. and not C. aha. The leaves of that specimen are larger 

 than in ('. atra and the calycine lobes ai'e many nerved. 



The original label was uuirked in Ilillebrand's handwriling Cijaina oidy : 

 the specific name atra was written by someone else, and as the color of the ink is 

 much fresher it would indicate that the plant was errt>neously identified by some- 

 (Uie of the Berlin Herbarium staff, and the original ('. atra was given away in ex- 

 change to some herbarium; the writer has, however, been unabh- to find it. 



The species is related to Ciiaiiea macrostcgia but differs from it in the dark 

 purple calyx and calycine lobes and corolla, the former being one-nerved instead
