possess a Inrijo roceptacular tube, with the g^'na'ceum inserted on 

 one of its sitles at a variable distance from its mouth. In Chryf^o- 

 btihinm and Licnnin, tlie insertion of the ovary is evidently as in the 

 Vninrtt, in the centre of the receptacle. In G. horhonica (figs. 493, 

 494) this point is already slightly excentric. The floral organization 

 is in other respects very near that which we have already observed 

 in the Lirnnia.s of the section MoquUea. The calyx and corolla each 

 j)ossess five imbricated leaves. The receptacle, lined by a thin layer 

 of glandular tissue, still bears on its edges about fifteen stamens 

 arranged as in C/iri/sobahuuis ohhnrpfolius ; each consists of a fila- 

 ment at first inilexed and then much exserted, and an introrse 

 two-celled anther dehiscing longitudinally. The filaments are only 

 united just at the base into a short collar like that of Chry sob al anus. 

 'i'he ovary covered over with long hairs contains two collateral erect 

 ov\iles, whose micropyles look downwards and towards the insertion 

 of the gynobasic style. This last is slender, rolled up in the bud 

 and then long and much exserted ; its stigmatiferous apex is not 

 dilated. The flower is a drupe with a thin mesocarp and a trigonous 

 one-seeded stone. Within the membranous seed-coats is a fleshy 

 exalbuminous embryo with its radicle inferior. 



In G. porosa^ another species of the same genus from Madagascar, 

 the iloral receptacle is more concave ; the insertion of the ovary, 

 corresponding with the edge of the receptacle, is hence higher up, and 

 there are ten stamens, not all of which are fertile. Two or three, in- 

 serted in the opposite edge of the receptacle to that which bears the 

 rcccptacular cup, remain as sterile tongues. The flower contains 

 one or two seeds with very fleshy embryos. 



Thus, of the two species included in this genus, the one has 

 fertile stamens all round the receptacle, and the other only on one 

 side ; we shall see that the same alternative occurs in Couepia 

 and Pan/Kui. The genus Grangcria consists of glabrous or bristly 

 shrubs, whose simple leaves possess two lateral caducous stipules. 

 Tlie flowers are in simple axillary or compound terminal racemes ; 

 eacli flower is borne on a slender pedicel axillary to a caducous 

 bract. 



In liirlella- (figs. 495-500), too, we find the same one-sided inser-
