H. Mann described Hbd.’s variety y, doubtfully in the genus Connarus as C.? 
Kauaiensis, and remarks that the two lower lateral leaflets, which are very small 
and have strongly revolute margins, are perhaps a diseased state. This is, how- 
ever, not the case, as in all forms examined from Kauai and Hawaii these stipel- 
liform leaflets are present. 
Hillebrand describes a variety @ with generally 3-foliolate leaves and acute an- 
thers which are longer than their filaments, from the Island of Hawaii, from the 
western, dry section of Kawaihaeiuka. The writer did not meet with this va- 
riety, though he found another form in the neighboring district of North Kona 
on the lava fields of Puuwaawaa, which proved to be new and is here described 
as follows: 
Var. tomentosum Rock var. nov.

This very interesting tree occurs on the lava flows of Mt. Hualalai, at Puu- 
waawaa, North Kona, Hawaii, where it is, however, not common. It was first 
collected by the writer, fruiting and flowering, on June 17, 1909 (no. 3695), and 
again during March, 1912, when several forms of this variety were found, which 
have been here described collectively. Type is 10207 in College of Hawaii Her- 
barium.
