Order CLXXII. CEDRELACE^.— Cedrelads. 



Cedrelese, Brown in Flinders, 64. (1814).— Meliaceae, § Cedreleae, DC. Prodr. 1. 624. (1824).— 

 Cedrelaceae, A. de Jussieu Memoire (1830) ; Ed.pr. L\x\iii. ; Endl. Gen. ccxxvi.; Meisner p. 47. 



Diagnosis. — Rutal Exogois, with consolidated capsular fmit, deeply monadelpltous or 

 free stamens, and numerous winged seeds. 



TreeSj with timber which is usually compact, scented, and beautifully veined. Leaves 

 alternate, pinnated, without stipules. Flowers in tenninal panicles. Calyx 4-5-cleft. 

 Petals 4-5, longer. Stamens 8-10 ; the fila- 

 ments either united into a tube (Smetenieae), 

 or distinct (Cedi'eleee), and inserted into an 

 hypogpious disk. Style and stigmas simple. 

 Cells of the ovary equal in number to the 

 petals, or fewer (3), with the o^'ules ascending 

 or pendulous, anatropal, 4, or often more, im- 

 bricated, in two rows. Fi*uit capsular, with the 

 valves separable from the thick axis, with 

 whose angles they alternate. Seeds flat, 

 winged ; albumen thin or none ; embryo ortho- 

 tropal, straight ; cotyledons flattish or fleshy ; 

 radicle very short, next the liilum. 



Nearly related to Meliads, in whose affini- 

 ties they participate, and chiefly distinguished 

 by their winged and indefinite seeds. Flin- 

 dersia, a genus estabhshed by Brown in the 

 Appendix to Captain Flinders' Vogage, differs 

 from Cedrelads both in the insertion of its 

 seeds, which are erect, in the dehiscence of its 

 capsules, and also in having moveable dissepi- 

 ments : these last, however. Brown considers 

 as segments of a common placenta, having a 

 peculiar form. Flindersia, and Chloroxylon 

 are distinct from the rest of the Order, in 

 having the leaves dotted with pellucid glands, 

 in which respect they serve to connect Cedre- 

 lads with Citronworts, and, notwithstanding
