XATUHAL UJfiTOUY OF PLANTS. 



all these differences of lorni, the petals are still very thick and valvatc 

 in the hud. In y/. muricaicC (figs. 2G0-271), while the outer petals 

 retain these characters, the inner ones are thinner towards the edges, 

 and are strongly imbricated in aestivation. 

 The same occurs in A. inculucrata,' in which, 

 moreover, the flower is enveloped by two 

 bracts, that form a complete sac for the 

 young bud. In all these species the stamens, 

 inserted in a spiral on a hemispherical re- 

 ceptacle, are surmounted by a thick, truncate, 

 (>])long or oval dilatation of the connective, 

 and are, in a word, analogous to those of 

 IJraria. Each carpel contains one or two^ 

 nearly basilar ascending ovules, with the 

 micropyles outwards and downwards ; and 

 the multiple fruit is a fleshy berry in which the seeds are scattered, 

 and whose surface is nearly smooth, reticulate, or covered with 

 obtuse projections or recurved prickles. 



In one small-flowered species from Mexico, the characters of the 

 female organs and the fruit are the same ; but the flowers, few in 

 number, have in the bud the globular form found in most Hocageaa ; 

 hence the name of the species, J. glohifora ;* the stamens are exactly 

 those of several species of the same genus Bocagca, the anther-cells 

 being surmounted by a narrow conical projection of the connective 

 (fig. 274). The inner petals are quite wanting in this species 

 (fig. 273). It is, however, impossible to separate this plant from 

 the genus Anovn, of which it constitutes a distinct section under the 

 name of AnoncUa. 



Half a hundred species of Anonn are admitted ; but this number 



wanting or reduced to smnll Hcales. These iniglit 

 be further subdivided Bccording to the pre- 

 flonition of tlic c'r)rolln, and the very different 

 ino«lilic«liong of form tliut it affects in the bud, 

 of wliicli we huve just spoken,
