Ciianea nnJi-mc-tangcrc differs from Cyanea scabra in the spinescent leaves 

 and in the corolla lobes, which are smooth instead of scabrous. The corolla lobes 

 are usually smooth; only in one plant, no. 12834, could the writer detect a muri- 

 cation of the corolla lobes in the bud. Muricate corolla lobes are evidentl.y not a 

 very reliable character, similar to the variability of the length of calycine lobes.

C. ijlatyplnjlJa belongs to the group of ('. scabra and C. noli-me-iangere, but 

 is quite distinct from either. It is only found in the lower forest region on the 

 windwai-d side just a few hundred feet al)ove sea level. 



Ilill(4)rand's no. 168 bears the remark: — Determined at Kew as BoUandia 

 lhni\bol'ltiaiui. A. Gray's remark that it resembles Gaudichaud's Rollaiidia 

 ci'ispa is certainly erroneous; they can be distinguished at a glance. The muri- 

 cation on peduncle and petioles as well as on the stem varies as in C. scabra.
