nate longer, glandular at apex, imbricated. Stamens 5, alterni- 
petalous (in female flower sterile); filaments inserted outwardly 
below hypogynous 5-agonal disk, subpetaloid at base, ciliate or 
villous, interior naked or with 2 lateral scales, more or less high, 
stipate ; anthers introrse, 2-rimose. Germen very shortly stipitate 
beyond disk (in male flower rudimentary), 3-agonal, 3-locular ; 
styles short, 3-lobed, inwardly stigmatiferous, sometimes reflexed 
at apex; ovules in each cell solitary or 2-nate, inserted below apex 
at internal angle, descending ; micropyle introrse, superior; raphe 
dorsal. Fruit samaroid, with linear-oblong nucleus, subdrupaceous, 
3-winged ; wings vertical, finally dry; putamen hard, 3-agonal, atte- 
nuated on both sides, traversed by resiniferous channels; cells 3, 
l-spermous (or abortive 1, 2). Seeds somewhat terete ; testa fibrous ; 
albumen fleshy; embryo straight; radicle very short, superior ; 
cotyledons linear-oblong.—Trees ;’ trunk simple ; leaves alternate, 
imparipinnate ; folioles multijugate, alternate, linear-oblong or falci- 
form, entire or serrate, glanduliferous at margin ; flowers’ in large 
terminal elongated cymiferous racemes; bractlets very small 
(Western India’). 
106? Picrodendron Pu.’—Flowers “dicecious ;” male ...? Fe- 
male flowers 5-merous ; sepals small and petals (?) same in number, 
alternate, laterally glandular.’ Germen free, 2-locular; style 
branches 2, linear, at apex stigmatiferous revolute ; ovules in cells 
2, collaterally descending; micropyle extrorse, superior, blocked 
by rather thick obturator. Drupe l-spermous (one cell effete) ; 
“putamen finally sub-2-valved ; seeds sulcate, exalbuminous ; testa 
membranous, insinuated between folds of embryo; cotyledons 
plicate ; radicle superior.”—A small very bitter tree; leaves alter- 
nate, 3-foliolate ; folioles entire; flowers “male amentaceous axil- 
lary ;”’ female axillary, solitary, pedunculate® (Cuda’).

1 Lofty, not bitter. 
* Rather large; somewhat purple when dry. 
3 A genus very anomalous among the Æu- 
taceas, nearly allied to Boswellia, and perhaps 
better placed among the Burseree. Apotropous 
ovule rarely observed in this order.
