Rubiaceae. 
Hillebrand records it from West Maui, Molokai and Lanai; it is known to the 
writer only from the latter island. The size of ealyx and corolla varies con- 
siderably in this species; the larger flowers being an indication of dimorphism.

Hillebrand records this tree from South Kona, Hawaii, and Kawaihaeiuka of 
the same island. This tree is not known to the writer, but is undoubtedly very 
close to B. sandwicensis from which it seems only to differ in the toothed calyx 
and one seeded fruits. These last three species may form in reality only a very 
variable species.

The genus Straussia consists of 7 oe all of which are peculiar to the Ha- 
waiian Islands. Heller’s two new species, St. psychotrioides and St. pubiflora, 
described in the Minnesota Botanical Studies Bull. IX. (1897) 904 & 905, are 
not very distinet species and will undoubtedly be referred to St. Kaduana. 
The genus is not found at higher elevation than 4500 feet, but descends some- 
what lower than 1000 feet. To the five species originally known the writer has 
added two new ones; a third new one was described by H. Léveillé.
