488 NATURAL HISTORY OF PLANTS. 
65. Casimiroa Luav. & Lux.'—Flowers polygamous-dicecious ; 
receptacle depressed conical. Sepals usually 5, free or connate at 
base, narrow, imbricated. Petals same in number, alternate, valvate, 
incurved at apex. Stamens 5, alternipetalous ; filaments inserted 
below, very small annular disk, free; anthers introrse, subeordate or 
subsagittate at base, longitudiually 2-rimose (in female flower 
smaller, effete). Germen (rudimentary in male flower) free, sessile, 
subglobose, cells 5, or more rarely 6-8 ; style short, thick, after- 
wards divided into a like number of thick reflexed stigmatiferous 
lobes; ovule in each cell 1, inserted at internal angle, descending ; 
micropyle extrorse superior’ crowned with 2-lobed obturator. 
Drupe large, pomiform, depressed-globose; pulp sapid; pyrenas 
usually 5, crustaceous, 1-spermous ; seeds oblong-compressed ; hilum 
ventral, elongated ; testa subcoriaceous ; embryo exalbuminous ; ra- 
dicle short ; cotyledons fleshy, amygdaloid—Ramified trees ; leaves 
alternate, digitate, 3-7-foliolate ; folioles petiolulate, entire or slightly 
serrate, glabrous or pubescent, thinly pellucid-punctuate ; flowers* in 
more or less ramified axillary cymiferous racemes* (AZewico’). 
66. Phellodendron Rvupr.'—Flowers dicecious ; sepals 5-8, free 
or connate at base. Petals same in number, alternate, inwardly at 
middle pilose-carinate, valvate, incurved at apex. Disk shortly 
columnar. Stamens (small, effete in female flower) equal in number 
to petals, and alternating with them; filaments short, subulate ; 
anthers large, incurved, introrsely 2-rimose. Germen (rudimentary 
5-lobed in male flower) 4, 5-locular; style ...? ovules (solitary ?) 
descending ; micropyle extrorse superior. Drupe pisiform, 5-pyre- 
nate; mesocarp oleose-lacunose ; seeds compressed; testa black, 
crustaceous ; albumen fleshy, scanty; embryo rather straight ; coty- 
ledons flat, oblong; radicle superior.—A glabrous tree; leaves 
opposite, imparipinnate; folioles opposite, petiolate, articulate, 
oblong-lanceolate, acuminate, unequal at base, scantily pellucid- 
punctuate; flowers in compound terminal and axillary racemes, 
sometimes subcapitate ; pedicels articulate (Zanchouria’).
