484 NATURAL HISTORY OF PLANTS. 
shrubs ; leaves alternate, opposite or 3-nate, petiolate, 1-3-foliolate 
or imparipinnate ; flowers in spikes or simple, much elongated ra- 
cemes, terminal or axillary; pedicels below middle or at apex 
bracteolate (Trop. and Subtrop. Cont. aad Ins. America’). 
58. Esenbeckia H. B. K°— Flowers nearly of Péilocarpus, 4, 
5-merous ; petals imbricated or valvate (I/etrodorea’). Stamens 4, 5, 
outwardly inserted below subentire disk, or between alternipetalous 
lobes; anthers short, often 2-dymous, mucronate. Carpels 4, 5, 
oppositipetalous, in 4, 5-locular germen more or less high, connate, 
dorsally at apex granulate or tuberculate; style inserted at summit 
of depressed germen, stigmatiferous capitate subentire or lobed at 
apex; ovules in cells 2, descending ; micropyle extrorse, superior. 
Capsule subglobose or depressed, smooth (Awa/a‘) or oftener echinate 
or muricate, septicidally 5-coccous ; cocci 2-valved ; endocarp more or 
less solute, elastically 2-valved. Seeds oblong; hilum linear ; thick 
cotyledons of exalbuminous embryoes often unequal, 2, 3; radicle 
superior, short. Other characters of P/i/ocarpus.—Pellucid-punctuate 
trees or shrubs ; leaves alternate, opposite, 1-3-foliolate ; petiole flat 
or winged, sometimes dilated at base (J/etrodorea), and including 
axillary bud; flowers’ in ramified cymiferous racemes, axillary or 
terminal’ (Zrop. and Subtrop. Cont. and Ins. America’). 
59? Helietta Tur.®— Flowers (nearly of Hsenbeckia) 3, 4-merous ; 
sepals connate at base, imbricated. Petals longer, imbricated, finally 
reflexed. Stamens equal in number to petals, outwardly inserted 
below concave 6—8-crenate disk, free; anthers at summit of reflexed
