107. Algernonia H. Bn.^ — Flowers monoecious; male calyx 

 unequally-3-5-lobed, imbricated, thick glandular -incrassate at base. 

 Stamen 1, central ; filament not articulate ; anthers erect apiculate, 

 2-dymous, cells 2, long aduate, laterally rimoso. Female calyx 

 cupular, glandular-3-denticulate, persistent. Germen o-locular, un- 

 equally-lobate-dilated below apex of cells ; cells 1-ovulate, style 

 erect columnar, afterwards 3-fid ; lobes simple rather compressed, 

 inwardly stigmatiferous, Fruit suberous-capsular, tiually 3-coccous, 

 depressed-turbinate and horizontally as if in sublobed ring dilated- 

 winged, shortly apiculate ; seed . . . ? — A small tree ; leaves alternate 

 terminal densely spicate ; inferior spikes few female. [North Brazil ?) 



108. Dalembertia H. Bn.^ — Flowers monoecious apetalous; male 

 1-androus; filament at first incurved, apex of anther introrse,* 2- 

 rimose bearing dorsally and at middle a bractlet,'' articulate below the 

 insertion of this. Sepals of female flowers 3, sometimes connate at 

 base, small, imbricated, furnished at base with 2 stipulate glands 

 and higher at margin with smaller unequal ones. Gynœceum (of 

 Exccccaria) 3-merous ; cells alternating with sepals ; style erect at 

 middle 3-fid ; branches recurved or revolute, inwardly stigmatiferous. 

 Capsule 3-coccous ; seeds exarillate glabrous. — TJndershrubs ; leaves 

 alternate petiolate, 2 -stipulate, rhomboid, repando-dentate or lobed, 

 more rarely sub-entire ; flowers ° in terminal racemes l-or2-sexual ; in- 

 ferior in androgynous the female few ; pedicel erect or refracted ; bracts 

 imbricate, 1 -flowered, apiculate, at base thick 2 -glandular. (Mexico.'') 



109. Anthostema A. Juss.** — Flowers monœcious; male calyx 

 membraneous small, uuequally-3-6-dentate. Stamen 1, central fila- 

 ment erect subulate ; anthers of terminal cells longitudinally rimose. 

 Calyx of female flowers gamophyllous, 3-5-fid. Germen 3-locular;
