Flacourtiaceae-Thymelaeaceae. 
ciliate, — 4-lobed; Sete flowers: sepals 4, occasionally 5, stigma 2-lobe d, on a short 
style; ‘plac ntas (2, r v8), a with 3 pendulous ovules; fruit subglobese to obov td, 
beaked with the ee: Fle. 
This tree, which is ies: ealled Maua by the natives, is to be found on all the 
islands of the group, with the exception of Oahu and Kauai. It differs mainly 
from its cogener in its leaves, which are not entire, but crenate. It is a much 
snialler tree in certain localities, only reaching a height of 10 to 15 feet, pre- 
fering the very dry lands on the leeward sides of Lanai, Molokai, Hawaii, and 
Maui. On the latter island on the southern slopes of Haleakala, and on Hawaii 
in the rain forest of Kau, it reaches its best development: there have been ob- 
served trees 40 feet in height with a trunk of over one foot in diameter. This - 
Maua presents a very poor appearance on the west end of Molokai, where in- 
dividual trees are still to be found on the slopes of Mahana valley. Windswept 
and stunted, it stands as a relic of by-gone days, the remnant of what was once 
a beautiful forest. Its associates, Gardenia Brighami (Nau), Reynoldsia sand- 
wicensis (Ohe), Kokia drynarioides (Kokio), and others, of which only a 
few are left, have experienced a similar fate, and in time not far hence will be 
things of the past. On Hawaii, it grows on the aa (rough) lava fields of Puu- 
Waawaa and Huehue, North Kona, and Kawaihaeiuka (2000 feet), and at an 
elevation of 4000 feet on the slopes of Mauna Loa on the land of Keauhou near 
Kilauea voleano. Here the tree is larger and of similar size to the Maua of 
Kauai and Oahu. On Lanai it may be found on the dry ridges as well as on the 
flat land of Kaa, where a peculiar forest of an area of perhaps 30 acres has with- 
stood the ravages of cattle and sheep, but, as on Molokai, is rapidly succumbing. 
On Maui it grows above Makawao and on the southern slopes of the erater of 
Haleakala on the lava field of Auahi. district of Kahikinui, at a height of 2600 
feet above sea level. Both Mauas blossom usually in midsummer, but no par- 
ticular month ean be stated, as the flowering period varies greatly according to 
locality and environment. 
This species is closely related to the Tahitian Yylosma suaveolens Forst., 
while the other Maua approaches very closely Yylosma orbiculatum from 
the Viti, Marquesas, and Tongan islands 
This species is quite variable. Boueaoc from the west of Molokai are quite 
distinct from those of East Maui, above Makawao; from the latter place the 
racemes are the longest in any specimen of this species, being 25 to 30 mm long 
on the naked branch below the leaves, while in those from Molokai the racunee 
are very short and axillary only. In regard to the leaves, the crenation differs 
very much also, some having almost entire leaves. 
THYMELAEACEAE. 
The family Thymelaeaceae is a rather small one, consisting of 37 genera se : 
about 455 species. With the exception of the Polar zones, the family is “h 
tributed over the whole globe, and ranges from Terra del Fuego to Canada,
