ANONACE.E. 21:? 



inverted truncated pyramid, whose lar^^^er base slants very obliquely 

 downwards and inwards, and is terminated above and internally by a 

 sort of beak, here still short and obtuse, but which we shall see 

 becomes far more marked in several of its congeners. The surftice 

 of part of the connective is covered with warty, glandular, finely- 

 mammillated projections ; on the sides, and somewhat externally, are 

 the two anther-cells, which dehisce longitudinally. The gynajceum 

 consists of a variable number of carpels. Each ovary contains one 

 or two nearly basilar ascending ovules, whose micropyle looks down- 

 wards and outwards. The style is club-shaped, slightly bent, and 

 obtuse at the tip. The fruit is multiple, composed of a variable 

 number of stipitate one-seeded berries. 



Several other species from the same country are now known,^ 

 of the same general structure, and only distinguished from the 

 last by the somewhat variable number of stamens. The outermost 

 may disappear, when the androceum will appear to consist of a 

 single whorl, or in others the outer stamens are not quite absent, 

 but become sterile (fig. 252). The gynseceum does not always con- 

 tain the same number of ovules. Certain species have only one in 

 each ovary, while others contain a variable number inserted along 

 the inner angle in two vertical rows. Hence the fruits are not 

 always one-seeded, sometimes forming chaplets like those of U/io/ia 

 proper. As for the perianth, its form is \Qvy variable. The bud 

 may be elongated and ovoidal, and the inner petals, more contracted 

 at the base, form a corolla like that of several Mitrepliorea, except 

 that the claws are less elongated. But the character which varies 

 most from one species to another is the form of the stamens. The 

 projection of the connective, the size and direction of the sort of 

 oblique beak surmounting it internally, the thickness of its upper 

 part, the glandular mammillated state ot its surface, and finally, the 

 lengthened obliquity of the anther cells — these are the features that 

 are almost always clearly changed in passing from one species to 

 another, and that often become peculiarly marked in the plants we 

 are now about to consider.
