Mr. Bentuam’s Account of two new Genera allied to Olacinee. — 679 
Tribe II. Orne x. 
Ovarium a basi uniloculare. Ovulwn (saltem per anthesin) unicum, minimum, 
ab apice placentæ liberæ centralis pendulum. Stylus centricus. Semen 
spurie erectum. Inflorescentia axillaris, racemosa, 
5. Opicta*. Calyx minimus. Petala 4, 5, libera, decidua. Stamina hypo- 
gyna, fertilia tot quot petala et iis opposita, sterilia totidem petalis alterna 
Squamæformia. Stylus brevissimus. Stigma truncatum. 
6. Cansseraf. Calyx minimus. Petala 4 (rariüs 5 ?) in corollam gamopeta- 
lam diu persistentem coalita. Stamina Opilie. Stylus longior; stigmate 
crasso lobato. 
Tribe III. IcaciNEx. 
Ovarium a basi uniloculare v. excentrice et complete triloculare, Ovula in quo- 
que loculo duo ab apice placentæ hinc ovario adnate collateraliter affixa 
pendula, in loculo superposita, funiculo altero elongato. Stylus excentri- 
cus. Semen pendulum. Inflorescentia cymosa, axillaris v. terminalis. 
7. GowrHaNpmaf. Flores abortu unisexuales. Calyx parvus immutatus. 
Petala 4. Stamina in maribus tot quot petala et iis alterna, omnia fer- 
tilia clavæformia antheris innatis, sterilia nulla. Inflorescentia axillaris, 
in maribus cymosa, in foemineis simplex ? | 
8. Teactna§. Flores hermaphroditi. Calyx parvus immutatus. Petala 5. 
Stamina totidem iis alterna, sterilia nulla. Ovarium 1-loculare. Fruc- 
tus ovoideo-oblongus. Inflorescentia terminalis. 
* Opilia amentacea, Roxb., indifferent specimens, in flower only ; and excellent specimens, in flower 
also, of O. celtidifolia, or Groutia celtidifolia, Guillem. Fl. Senegamb., p. 101. t. 22, gathered by 
Kotschy in Æthiopia, n. 471. The two species certainly appear to differ in the form of the leaves as 
well as that of the bracteæ. 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 flower and fruit. 
1 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 seen 
neither female flowers nor fruit, but they are described by Wight, Illustr. pp. 102-3.
