This species differs very little from Bobea sandwicensis Hbd. Its outward ap- 
pearance, color of leaves, and branching habit, are exactly the same in both species. 
When neither in flower nor fruit it would be absolutely impossible to separate 
the two species. The only difference is that in the species in question the 
flowers are single and the fruits have from 4 to 6 pyrenae, while in Bobea 
sandwicensis the inflorescence is eymose but usually of only 3 flowers, and with 
fruits of 2 pyrenae; otherwise the trees could not be distinguished. 
Bobea Hookeri Wbd. was collected by the writer on Molokai in the open dry 
gulehes below Mr. G. P. Cooke’s residence, Kauluwai, at an elevation of 2000 
feet, only a single tree was observed, (no. 6177 flowering and fruiting March 26, 
1910). It also grows on the lava fields of Auahi, district of Kahikinui, southern 
slopes of Mt. Haleakala, Maui; there the writer met with a single tree with a 
large trunk vested in a gray large-scaly bark, (see plates 182 and 183) ; it had 
three main trunks each of a foot or more in diameter. It is associated with 
Alectryon macrococcus, Tetraplasandra meiandra var., Pittosporum, Dracaena 
aurea, and others. It is one of the rarest trees in the territory. Hillebrand 
records it from Oahu, from the valleys of Wailupe and Makaleha, but it was 
never met with by the writer on Oahu.

The writer collected this species on the Island of Lanai on the dry open 
slopes below Koele, and near the edge of the Mauna Lei canyon. It is quite 
numerous and grows in company with Siderorylon spathulatum, Gardenia Brig- 
hami, Chrysophyllum polynesicum, and others. 
It is a medium sized tree about 20 to 25 feet in height, has a short trunk 
(about 4 feet), but a large round and spreading crown, and is very freely 
branching. (Flowering and fruiting July 26, 1910. Rock and Hammond, no.
