Rutaceae. 
The Anonia or Alaniwai is one of the handsomest species of Pelea. It is re- 
corded by Wawra and Heller as a shrub 3 feet high. The writer collected ma- 
terial of this species first September 24, 1909, and again October, 1911. It grows 
only on the Island of Kauai on the summit of Mt. Waialeale, a big flat swamp at 
an elevation of 5200 feet. It is a small tree with a straight trunk of 4 to 5 feet 
and reaches a height of 15 to 20 feet. The mountain is alw ays enshrouded by 
clouds and it is extremely difficult to see farther than a few feet. On the day 
of the writer’s last ascent the sky was perfectly cloudless and a thorough survey 
could be made of the vegetation, which resulted in the discov ery of a number of 
new species, and also furnished additional data in regard to the plants already 
known. During the writer’s first visit to this most interesting mountain, the 
cold was so intense, the wind blew with such great force, and rain eame down 
in such torrents, that it was impossible to remain longer than a couple of hours. 
The second time, however, the writer was more fortunate. Collected flowering 
and fruiting September 24, 1909, no. 4975, and October, 1911, no. 8883 in the 
Herbarium of the College of Hawaii. Heller records the plant as a shrub 3 to 4 
feet high from the bog of Wahiawa, Kauai; this latter locality is at a much 
lower elevation, about 3000 feet.

Following is a quotation of A. Gray’s brief description of the above species: 
“‘P. glabra; foliis ternis oblongo-spatulatis basi auriculatis sessilibus; flori}us 
fasciculatis ad axillas foliorum delapsorum secus caulem virgatum brevissime 
pedicellatis ; capsula quadripartita.”’ 
He says: ‘‘The specimen, taken from an upright, nearly simple shrub, bears 
only a little fruit, and a few fertile ovaries, from which the perianth, stamens, 
ete., have fallen. The virgate stem is very leafy above; and the flowers have 
been produced lower down, in small fascicles from the ‘ai of earlier leaves, 
now fallen. Plant glabrous throughout. Leaves verticillate in threes, coriaceous, 
pale, oblong-spathulate, obtuse, auriculate at the base, sessile, from 3 to 5 inches 
long, veined and dotted nearly as in the preceding species; the midrib salient 
underneath. Ovary more deeply lobed than in P. clusiaefolia, being united only 
at the base; style has mostly fallen. Capsule deeply four-parted; the cocci oval- 
oblong, otherwise similar, as apparently are the seeds to those of Pelea clusiae- 
olia. 
‘Forests of Hawaii, on the flank of Mauna Kea.”’ 
How Hillebrand could have taken this plant for a Platydesma is difficult to 
understand. Even Engler in the Natiirlichen Pflanzenfamilien places it under 
the latter genus.
