Hibiscadelphus hualalaiensis (Malvaceae), 45243. From 
Honolulu, Hawaii. Presented by Mr. Joseph P. Rock, 
Botanist ,. College of Hawaii . A tree, 16 to 23 feet 
high, with erect trunk, white bark, somewhat reniform 
leaves, and small ovate capsules, belonging to the al- 
most extinct genus , . Hibiscadelphus, of the three species , 
of which two are represented by a single tree each, 
and the present one by a dozen or so living trees. 
Seeds of all the species are growing, however, in 
various Hawaiian gardens. This exceedingly interest- 
ing and distinct species was found by the writer in 
the year 1909 on the lava fields of Mt. Haulalai, in 
North Kona, Hawaii, and in the forest of Walhou of 
the same district, where about a dozen trees are still 
in existence. The writer revisited the above locali- 
ty in March, 1912, and found the trees in flower, 
while on his previous visit, June 18, 1909, only a » 
few worm-eaten capsules could be found. The trees are 
badly attacked by several species of moths which feed 
on the leaves and mature capsules. Mr. Gerrit Wilder, 
however, succeeded ingrowing a few plants from healthy 
seeds collected by the writer. (Adapted from Rock's 
Indigenous Trees of the Hawaiian Islands, p. 301.)

is produced the henna or alhenna of the Arabs (cyprus 
of the ancients), a yellow dye which is used in Egypt 
and elsewhere by women to color their nails, and by 
men to dye their beards, and for similar purposes. It
