CELASTRACEJE.

Guyana, with leaves alternate, petiolate, entire, coriaceous, glabrous, 

 penninerved, reticulate, subtriplinerved at the base, accompanied by- 

 two very small caducous stipules. Its flowers are inserted in the 

 axil of the leaves in (spurious) umbels supported by a small common 

 peduncle. 



IV. AZIMA SERIES. 



In this group, long considered as forming a special family under 

 the name of Salvadoraceœ, we may study first Azima 1 scandais (fig. 

 13-15), formerly described as type of the genus Actegcton? Its flowers 

 are ordinarily tetramerous and polygamo-diœcious. The calyx, gamo- 

 sepalous and valvate, is divided above into four lobes. 3 The petals, 

 alternate, sessile, narrow and elongated, soon cease to touch at the 

 margins. In the intervals are inserted, on a narrow receptacle, four 

 stamens whose thick free filaments, in the male flower, are inserted 

 round a rudimentary gynœciurn, and are each surmounted by a bilocu- 

 lar introrse anther dehiscing by two longitudinal clefts. It is sterile 

 in the female flowers in which the corolla and andrœcium are united 

 below in a very short tube, with a free superior gynsecium, consisting 



Azima {Aetegeton) scandens.

of an ovary with two cells, surmounted by a short style, soon divided 

 into two large branches, stigmatiferous within and on the margins.
