Dorstenia cuspidal n. 



they are collected on the little developed but much branched axes of 

 one or two axillary pedunculate cymes resembling at a distance a 

 small capitule. In Bleek?'odia, shrubs of 

 Borneo and Madagascar, the flowers are 

 also grouped in capituliform cymes, a 

 female being central and terminal, sur- 

 rounded by younger male flowers in con- 

 siderable number. Both have a valvate 

 calyx in the form of a gamophyllous sac 

 in the female ; and the embryo, destitute 

 of albumen, has very unequal cotyledons. 

 Sloetia, a Javan shrub, has an inflo- 

 rescence, the elongate and flattened axis 

 of which, covered with floral glomerules, 

 has the general form of male inflorescence 

 of the Mulberry and Madura. But a 

 single one or a very small number of the 

 glomerules (which are collected on one of the faces of this receptacle 

 and on a portion of the other) bears in the centre a tetramerous female 

 flower with sessile and prominent gymecium. All the rest are formed 

 of only male flowers, trimerous and triandrous, with valvate calyx. 1

III. BREADFRUIT SERIES. 



The Breadfruit trees 2 (Artocarpus) (fig. 114-118) have given their 

 name to this group, often raised to the rank of a family, but they 

 are not the most complete type. They have monoecious flowers 

 collected in great number on unisexual inflorescences. In the male 

 flowers is observed a perianth formed of two or four calycinal 



1 In this group has been placed, not without 

 some doubt, Trymatococcus Pœpp. a Brazilian 

 tree the juice of which, it is said, is not milky ; 

 for if its stamens have, according to Poeppig, 

 filaments indexed in the bud, they do not 

 always appear so in the adult flowers under 

 our eyes ; and in most of its characters, the 

 plant seems very near Pseudolmedia. There 

 is also an African T. — Calms lactescens 

 (Blanco, FI. d. Filip.eà.. 1, 698.— Bur. Prodr. 

 xvii. 278), remains also a most doubtful genus. 

 The flowers of the two sexes are said to be 

 mixed in axillary pedunculate fascicles or 

 glomerules. The males have four stamens 

 elastically straightened at anthesis, and the 



females have a superior ovary, surmounted by a 

 style with two long revolute branches. (See p. 

 167, note 12).
