terminal, solitary and supported on a short peduncle ; but the ovary 

 has only two uniovulate cells, and the small drupe has only two 

 putamens as in most Uragogas. 



Thus defined,^ the genus Uragoga numbers at least eight hundred 

 species ^ belonging to all the tropical and subtropical regions of the 

 globe ; ^ many are still little known. 



Beside Uragoga are placed Declieuxia, LasianthuSj Saprosma and 

 Mijrmccodia. All have a valvate corolla, uniovulate ovarian cells, 

 with an ovule similar to that of Uragoga. All have drupaceous fruit 

 and ascending albuminous seeds. Declieuxia, American herbaceous

•* Mesoptcra Maingayi Hook. f. ((7m. ii. 130, 

 n. 277) to us imperfectly known, has the pen- 

 tamerous flowers of Uragoga, with a valvate 

 corolla and uniovulate ovarian cells ; ovule 

 ascending-, micropyle exterior. It is distin- 

 guished by the summit of the style " large stig- 

 matic capitately lU-lohed." We have not seen 

 this organ. It is a tree of Malacca with axillary 

 cymes. Neither can we determine definitively 

 the place of the genus Thicsia (fig. 266), w^hich 

 we have proposed {Adansoiiia, xii. 355) for a 

 remarkable tree of Guyana, with branches 

 alternately compressed and phyllodiform. In 

 the axil of these large unsymmetrical leaves, the 

 flowers are united in biparous cymes with 

 stumpy axis bearing under them four bracts, 

 two of which are narrow and acuminate, the 

 two others alternate, wide, membranous, con- 

 cave or cucullate, each enfolding one of the 

 lateral flowers. The ovary, inferior, is bilocular 

 with a single ascending ovule in each cell, and 

 the corolla is narrow-tubular, 4-lobed, val- 

 vate.
