According to Hillebrand the native name of this species is PualaJa. The 

 species is very distinct, but does not branch and shimld therefore come under 

 section nalmai formes: the mere fact that the stem is armed and the i)etioles and 

 peduncles muricate is no reason to include it with ('. scaJira and the other species 

 belonging to that section. Tlie writer's ('. aciilrati/lorn is decidedly armed, but 

 not branching, and has the outward appearance of ('. tn'tomanllia. which llille- 

 branil includes in section pnliiKu faniit s. Hillebrand "s variety scJiizocali/.r evi- 

 dently does not belong here; there is no specimen in Hillebrand 's collection of 

 this variety. It may. however, be related to the writer's ('. acuUatifofa from 

 the same region (Ilamalaia, E. Maui), where Lydgate collected the material of 

 that variety.

 bracts linear-lanceolate hispid, calyx green, glabrous, ovarian portion turbinate 

 12 mm high, the funnel-shaped connate calycine lobes 2 cm long, and irregu- 

 larly slit at the apex, the nerves indistinct, corolla short, fleshy, 4 cm long, 10 mm 

 wide, glabrate, waxy white with purplish streaks, the dorsal slit not quite extend

MOLOKAI: Gulch of Wailiauau in I'ainforest along streambed, Howering 

 August 13, 1918, L. il. Dunbar type no. 13118 in herbarium College of Hawaii. 



This variety differs from the species in the smooth stem and spineless leaves 

 and glabrate calyx and flowers; the bracts are apparently at the apex of the 

 peduncle instead of extending down to the stem. 



The variety was discovered by Mrs. L. M. Dunbar of jMolokai, who has shown 

 great interest in this group of plants.
