The ]\Iolokai specimens come close to Clermontia Gaudiehaudii in the very 

 .short dentiform calyeine lobes; the flowers are also less fleshy than in the Maui 

 specimens, which have broad fleshy deltoid calyeine lobes and corolla lobes 5 mm 

 thick; the leaves are, however, all dark green glossy above and paler beneath. 

 The species is otherwise much more robust than CL (idndiehniiiHi : its closest 

 relationship is. however, with the latter species. 



It is very common throughout the wet forests of West and East I\Iaui and 

 ]\Ioliikai. but is less common on Lanai. With CI. drepannmorpha it possesses 

 the largest flowers of the genus Clermontia.
