Mr. Bentham's Account of two new Genera allied to Olacinese. 679 



Tribe II. OpiUEiE. 



Ovarium a basi uniloculare. Ovulum (saltern per anthesin) unicum, minimum, 

 ab apice placentae liberae centralis pendulum. Stylus centricus. Semen 

 spurie erectum. Inflorescentia axillaris, racemosa. 



5. Opilia*. Calyx va\mm\xs. Petala 4, 5, libera, decidua. Stamina hypo- 



gyna, fertilia tot quot petala et iis opposita, sterilia totidem petalis alterna 

 squameeformia. Stylus brevissimus. Stigma truncatum. 



6. CANSJERAf. Calyx minimus. Petala 4 (rarius 5 ?) in coroUam garaopeta- 



1am diu persistentem coalita. Stamina Opilise. Stylus longior ; stigmate 

 crasso lobato. 



Tribe III. Icacine^. 



Ovarium a basi uniloculare v. excentrice et complete triloculare. Ovula in quo- 

 que loculo duo ab apice placentae hinc ovario adnatee coUateraliter affixa 

 pendula, in loculo superposita, funiculo altero elongato. Stylus excentri- 

 cus. Semen pendulum. Inflorescentia cymosa, axillaris v. terminalis. 



7. Gomphandra:^:. Flores abortu unisexuales. Calyx parvus immutatus. 



Petala 4. Stamina in maribus tot quot petala et iis alterna, omnia fer- 

 tilia clavseformia antheris innatis, sterilia nulla. Inflorescentia axillaris, 

 in maribus cymosa, in foemineis simplex? 



8. Icacina§. Flores hermaphroditi. Calyx parvus immutatus. Petala 5. 



Stamina totidem iis alterna, sterilia nulla. Ovarium 1-locuIare. Fr ac- 

 tus ovoideo-oblongus. Inflorescentia terminalis. 



* Opilia amentacea, Roxb., indifferent specimens, in flower only ; and excellent specimens, in flower 

 also, of 0. celtidifolia, or Groutia celtidifoUa, Guillem. Fl. Senegamb., p. 101. t. 22, gathered by 

 Kotschy in ^Ethiopia, n. 471. The two species certainly appear to differ in the form of the leaves as 

 well as that of the bractese. All the specimens I have seen of O. acuminata. Wall., are in too bad a 

 state for examination. 



t Cansjera Rheedii, Gmel. (C. malabarica, Lam., C. scandens, Roxb.), in Slower and fruit. 



X Gomphandra polymorpha, Wight, G. axillaris. Wall., and G. Penangiana, Wall., all male flowers 

 only. So far as these go I see no reason to doubt their being congeners to each other. I have seea 

 neither female flowers nor fruit, but they are described by Wight, lUustr. pp. 102-3.
