NATURAL HISTORY OF PLANTS. 
7. Peridiscus Buyra.'—Flowers hermaphrodite, apetalous ; sepals 
4, 5, unequal, subvalvate, finally patent-reflexed. Stamens «, hypo- 
gynous inserted round base of disk; filaments adpressed below to 
grooves, incurved at apex, finally patent; exterior sometimes thicker ; 
anthers suborbicular introrse, rimose at margin. Germen orbicular- 
depressed, 1-locular, all round nearly to middle thickened in annular 
vertical sulcate disk; styles 3, 4, short, distinct, tapering at apex ; 
ovules 6-8, inserted at apex of cells pendulous ; micropyle extrorse 
superior. “ Young fruit obovoid fleshy.”—A lofty tree; leaves large, 
integerrimus coriaceous lucid; flowers small in simple racemes, 
sometimes umbelliferous, fasciculate at old nodes of small branches. 
(North Brazil’). 
8, Lætia LœrL®— Flowers hermaphrodite apetalous; receptacle 
rather wide. Sepals 4, 5, wide subpetaloid, much imbricated, finally 
often reflexed. Stamens 10-15 (Casinga‘), or sometimes , hypo- 
gynous on eglandular disk, or with exterior subperigynous insertion ; 
filaments free; anthers introrse short or ovoid. Germen free, 1- 
locular; style simple, apex stigmatiferous, capitate, sometimes wide 
sessile (Z/iodia’), or shortly 3-lobed. Berry tardily 3-valved, interior 
often resinous-pulpous ; seeds externally pulpous, sometimes aril- 
late; testa coriaceous; embryo albuminous, straight; cotyledons 
wide, foliaceous, or rather thick.—Small trees; leaves alternate, ser- 
rate or crenate, pellucid-punctuate, more rarely coriaceous epunctuate 
(Scypholetia’); flowers axillary or terminal, glomerate or cymose, 
subcorymbose; bractlets small, sometimes (Scypholetia) larger, 
thick, connate in subentire or crenate calyciform involucel (Zrop. 
America’).
