For the same reasons, Trisenia Hook. F.,' vvliicli Father Mont- 

 rouzier' names Vanieria, should also be included in the ^Qnu^JIi/j/jcrtln. 

 The single carpel/ whose ovary contains as many as a dozen anatro- 

 pous ascending ovules, is surrounded by a large number of unequal 

 fertile stamens, with narrow two-celled anthers dehiscing laterally, and 

 bj a calyx of five imbricate sepals, alternating witli which we often 

 see but three or four petals. The flowers grow in terminal unilate- 

 ral spikes, like those other 

 Oceanian species of llihhertia, 

 called Hemipleuravdra, or those 

 Hemistemmas which grow in 

 Australia and Madagascar. 



These last have opposite, or 

 nearly opposite leaves, un- 

 like all the other species of the 

 genus Ilibberfln, as we limit 

 it,'' which are shrubs, or under- 

 shrubs, with exstipulate leaves, 

 whose petioles are articulated 

 at the base. About eighty 

 species are known,* without 

 counting those described as 

 such, but which should only ^ 

 be retained as varieties. 



The genus SchumacJierid 

 consists of plants whose ses- 

 sile or sub- sessile flowers are 

 grouped in unilateral inflorescences (fig. 140), like those of the 

 sections Henustemma, Trisewa, &c., of Hihbcrtia, from which, on the

^ Owing to this single carpel, Trisema is to 

 the other Jlibberfias with unilateral inflores- 

 cences, what M. monoc/t/na R. Br. is to the other 

 pleiogynous species of Australia whose inflores- 

 cence resembles its own. But it appears to us 

 impossible to retain this as a distinct genus (see 

 Adansonia, vi. 269).
