E OPIIORBIA CE.F.. 115 



J. ManiJiot is become the type of a special genus under the name 

 of Mamhot^ because in- its apetalous flowers, very similar on that 

 account to those of Cnidoscolus^ the stameual filaments, instead of 

 being borne upon a column surrounded by the disk, are free for the 

 greatest part of their length and are only united towards the base 

 by a central body which spreads out between them to form a sur- 

 based disk. The Manlhoh are herbaceous or frutescent, almost all 

 natives of S. America. 



Beside the preceding genera are placed : TannotUa, a shrub from 

 Madagascar, having the flowers of Jatrojiha, small or united in spike- 

 shaped cluster, the calyx however being valvate in the male flowers 

 and imbricated in the female ; Tourncsolia (Fr., Maurelle)^ Avhose 

 flowers, smaller than those of Jairopha but really constructed like 

 them, are in both sexes provided with a valvate calyx, and have 

 entire or more or less decplj^ cut petals, or these may bo wanting in 

 the female flowers. Almost all inhabit the warm regions, especially 

 those of America, where they appear under the form of herbs, 

 shrubs, or undershrubs, the organs generally impregnated with a 

 reddish colom-ing matter. Pamandra^ of tropical America, has 

 from six to eight stamens, the exterior oppositipetalous, inserted 

 round the central concavity of the receptacle. 



Monotaxis forms close to them a small sub-series {Monotaxidea;)^ 

 where the flowers, with the same general plan as the preceding 

 genera, have a valvate calyx, distinct and pendant anther cells, and 

 an embryo cylindrical or nearly so, with cotyledons nearly 

 equal in size to the radicle, instead of being flattened, foliaceous, 

 and much larger. This consists of Australian plants of jjcculiar 

 habit, suffrutescent, with small ramified stems and narrow leaves 

 recalling those of Ericacece. 



In Sarcoclinium^ consisting of shrubs from tropical Asia and 

 America, the flowers, very similar to those of Jatrojiha and Tour- 

 nefsolia, have a valvate male calyx and an imbricated female one, 

 petals the same or double in number to the sepals, two verticils 

 (complete or incomplete) of introrsc anthers, and flowers disposed in 

 small cymes on the axis of spikes or I'aeemes, sometimes very long. 

 Galearia^ li-um Malaysia and Java, has nearly the same flowers, but 

 the calyx is valvate and the petals concave or formed like hoods in 

 which are loilged the aniher cells of the alternipetalous stamens. 

 The ovary bi- or tri-loculur becomes a coriaceous fruit, indehiscent
