TEREBINTH ACEJE. 
233 
A tree about 15 feet in height : branches erect, terete, glab- 
rous, rimoso-punctulated. Leaves alternate, equally pinnated : 
leaflets 2- rarely 3-paired, subsessile, 2-3 inches long, and 1 
broad, oblong, obtuse or subemarginate at the apex, entire, ob- 
scurely veined, shining above, glabrous except the midrib which 
is minutely puberulous beneath, thin, membranaceous, impunc- 
tate : petiole sub-3-quetrous, striated, glabrous, 2 inches in 
length. Stipules none. Panicle terminal, sessile, composed of 
many branches: branches subdivided, compressed, angulose, 
aureo-puberulo-tomentulose, as also the pedicels, which are 
very short. Flowers numerous, white, fragrant, resembling 
in appearance, as well as in smell, those of the Hawthorn of 
Europe. Bracteas at the subdivisions of the panicle, minute, 
ovate, acute. ^Estivation imbricated. Calyx 5-partite, exter- 
nally puberulous ; divisions rotundo-ovate. Petals 5, roundish, 
shortly clawed, alternating with and somewhat smaller than the 
divisions of the calyx. Stamens 7, more usually 8, irregularly 
inserted between the lobes of an annular fleshy red puberulous 
disk ; filaments somewhat longer than the calyx : anthers ovate, 
2-celled. Ovary conical, villous, seated on the disk : style 
short (?) : stigma obtuse. Drupe size of a small cherry, with 
the rind glandulose, of a deep purple colour, 1 -pyrene: nut 
large, chartaceous, 1 -seeded : radicle superior, curved, the size 
of that of the common pea ; cotyledons fleshy. 
Only some of the trees bear fruit. The flowers would 
therefore appear to be polygamous. The fertile ones are fur- 
nished with both stamens and pistil ; in the barren, the latter 
must be imperfect. This is a handsome tree. It approaches 
nearly to the genus Amyiiis, but is distinguished from it by 
several marks, and among others by the leaflets not being pel- 
lueido-punctate. 
X. Spathelia. 
Flowers hermaphrodite. Calyx 5-partite, mem- 
branaceous, coloured. Petals 5, hypogynous, during 
aestivation imbricated. Stamens 5 ; filaments short, 
tricuspidate, dilated and villous at the base. Ovary 
subcorneal, S-angular, S-locular ; locules biovuled : 
style O: stigmas 3. Drupe oblong, S-locular, 3-go- 
nal with the angles alate, sometimes 2-alate and 2-lo- 
cular. Seeds oblong, solitary in each locule : albu- 
men fleshy : embryo straight, inverted : cotyledons 
lineari-oblong, slender ; radicle short — De Cand. 
Trees : leaves impari-pinnate ; racemes panieled, subtermi- 
nal. — Name, from arrab, a palm, from the shrub before us re- 
sembling that Family of Plants in several respects.
