S89 



Single cell, 1-2-ovulate. Ovules desccndent, with superior and 

 interior niicropyle. Seeds without or, more often, with albumen, 

 entire or lobate. Stems climbing. Leaves simple. Flowers dioecious, 

 monoperiantliate (except in Cardioptcris) with or \Aithout epicalyx. — 

 8 genera. 



The types wrongly attributed to it or avLosc place is still uncer- 

 tain ^ being removed, this family contains sixty-seven genera all be- 

 longing to the warmest countries of the world. The PJu/tocrenca'^ 

 twenty-two species of which are at present known, all belong to 

 the tropical and sub-tropical regions of the old world. The Mappicoi 

 have four American genera, two common to both worlds, and eleven 

 peculiar to the old world. The latter contain forty species. The 

 genera proper to America comprise ten, and of the twenty-five spe- 

 cies of those common to both worlds a dozen are limited to tlie old. 

 The majority of Burserccv belong to the old world, which, of nine 

 genera, owns five, including nearly eighty species out of the hun- 

 dred and thirty constituting the series. The three genera peculiar 

 to America only include ten species. The Bursercic, which, as we 



' These are, tcsiJcs limnphia, of which we 

 have spoken before (p. 286, note 6) : 



Ist. Aiirjia (LouK. Fl. Cochincli. ed. 1790, 

 337 ; — E.NDL. Gen. n. 5926). A Chinese tree with 

 impariiiinnate leaves, pentamerous, polyandroiis 

 flowers, di-upaceous sublenticular fruit. Giv- 

 ing hy incision a stimulant acrid resinous var- 

 nish (has been compared to lihus, and ap- 

 proaches, perhaps, on account of its numerous 

 stamens, Mduiioirhaa ':). 



2nd. Biiiica (Meissx. Gai. Cumm, 75 ;— B. II. 

 Gen. 420, n. 9 ; — March. Atmcard. 194 ; — Cain- 

 lesscdca Wioht and Arn. not Auctt.). Tree 

 from tropical Asia with opposite leaves. 

 Flowers in very ramified cymes, 3-o-merous, 

 calyx short dentate, petjxls imbricate, andro- 

 ceum isostcmonous, and gyn.'vceum whose uni- 

 locular ovary contains a des(;endent ovule, or, 

 more rarely, two slightly developed ovules. 

 The direction of these ovules is variable, the 

 fertile one is often found nearly horizontal, 

 the micropyle being superior (and exterior f). 

 The fruit is drupaceous, and the seed contains a 

 fleshy embryo {Mappii'a?).

receptacle, surmounted by a thickened circular 

 disk, whose depressed centre bears a small rudi- 

 mentary gymeceum, and whose periphery pre- 

 sents a very short circular calyx, three valvate 

 petals and six stamens, exterior to the disk 

 arranged on two vertioels. The filaments are free, 

 short, surmounted by a basifixod anther, dehis- 

 cent by two longitudinal clefts. The fruit is 

 said to bo a mouospermous and inferior drupe. 

 This genus is thus removed from the Bnrsei r?, 

 to which it is ascribed with doubt. Its glandu- 

 lar-punctate folioles are exactly those of a Pis- 

 tacia occidcntulis, but it is separated from this 

 genus by the organisation of the male tlower 

 and the adhosiou of its calyx.
