Order XXIX. HUMIRIACE^ (by Prof. Oliver). 



Flowers regular, hermaphrodite. Sepals 5, imbricate. Petals 5, deci- 

 duous, slightly contort-imbricate or subvalvate. Stamens 10-20 or indefi- 

 nite, hypogynous, usually more or less connate below ; filaments filiform or 

 narrow linear, compressed ; anthers versatile with 2 cells at the base of a pro- 

 duced conical fleshy connective. Ovary free, sessile, usually 5-celled. Style 

 simple ; stigma terminal entire or denticulate ; ovules solitary (or 2-3), 

 pendulous. Fruit drupaceous with a woody or bony indehiscent putamen or 

 pericarp, thick, woody, abounding in resin-cysts. Seeds albuminous (not 

 examined in the African species). — Usually glabrous resiniferous trees. 

 Leaves alternate, simple, coriaceous, exstipulate. Flowers in axillary or 

 terminal corymbose or subpaniculate cymes. 



A small Order confined to Brazil and Guiana, with the following exception. 



1. AUBRYA, Baillon ; Benth. et Hook. f. Gen. PI. i. 988. 



Petals very slightly imbricate or subvalvate. Stamens 10; filaments com- 

 pressed, slightly connate below or free {Baillon). Ovary 5-celled. Style 

 simple ; ovules solitary. Fruit globose or ellipsoidal with a thick woody 

 pericarp abounding in resin-cysts, indehiscent (?). Seeds not seen. — A large 

 tree. Leaves coriaceous, glabrous. Flowers in axillary and apparently ter- 

 minal pedunculate cymes. 



Although there are two or three discrepancies between the account of A. gabonensis as 

 published by M. Baillon and the result of my examination of a good series of specimens, 

 including some from the Gaboon, yet I can hardly doubt that we have the same species in 

 view. Aubrya is peculiar to W. tropical Africa. 



1. A. gabonensis, Baitt. in Adansonia, ii. 266. Leaves very coria- 

 ceous, oblong-elliptical, rather acute or with a short subacute acumen, 

 rounded at the base and at length narrowed into the petiole, obscurely cre- 

 nate-serrulate above, glabrous, venation but slightly prominent, either dark 

 red-brown or pale green when dry, 3-6 in. long, l|-2± in. broad; petiole 

 i~a in. Flowers in stout axillary cymes forked from about the middle, 

 shorter than the leaves, towards the ends of the branches or sometimes 

 clustered in the uppermost leaves forming a small terminal panicle, minutely 

 puberulous or glabrate. Pedicels stout, jointed at the base, about equalling 

 the suborbicular ciliolate sepals. Petals rather thick, four to six times ex- 

 ceeding the sepals. Stamens at length often separating. Ovary glabrous. 

 Fruit 1 in. or little more in diam.
