Platydesma.] RUTACEAE, 71 
Disk plane, slightly 4—8-lobed. Stamens 8, inserted outside the disk, 
the filaments united into a wide tube, the ant er-cells elongate, attached 
to each side of protruding lobes of the staminal tube, introrse, converging 
at the top. Ovary 4lobed. Style terminal, undivided, truncate, the 
stigmas indicated by 4 lines. Ovules 5—8 in each cell, suspended 
from a short and broad flat funis, hemitropous. Capsule dry, 4- ee 
loculicidal (or indehiscent), with a thin endocarp, several-seeded. Seeds 
eae aaa angular-convex, with a black shining testa. Embryo Pi i 
the le of a fleshy albumen, equalling it in length and width, 
my iii thin, broad and rounded, the radicle short, terete. — 
Small trees or shrubs, with a heavy turpentiny odor. Leaves opposite 
or whorled, with copious oil-dots, simple, entire. Hinweis in axillary 
cymes, rather large. — H. Mann, in Mem hat Soc. Nat. Hist. I, 529. 
A peculiarly Hawaiian genus, remarkable in the Order for its monadelphous stamens. — 
The principal nerves of the leaves divide at about %/s the distance from the midrib into 
two main branches which form prominent anastomoses wit e corresponding ones of 
the next nerves, thus constituting a sinuate ree mega nerve which is separat 
from the tind several series of secondary areoles
