go BUTACE^. 



a 4'ceUed nearly globular drupe.— Trees or shrubs, with simple opposite 

 leaves (or rather solitary leaflets) articulate on the petiole. 



A small genus, limited to tropical Asia and Australia. 



1. C. pedunculata, DC. Prod. i. 722; Wight, Illustr. t. 65. A small 

 tree. Leaves oblong, obtuse, 3 to 4 in. long, glabrous, articulate on a petiole 

 of I- to 1 in. long. Peduncles axillary, usually shorter than the leaves, bear- 

 ing" a small trichotomous panicle or corymb of yellowish-green flowers. Petals 

 about 3 lines long, recurved when open. Stamens scarcely longer, the fila- 

 ments pubescent on the edges. Ovary and torus woolly. Style glabrous. 

 Emit about 4 lines diameter, usually white: — C. resinosa, DC. 1. c. 



Common in the island, Champion and others. Rrequent in India, from Ceylon and the 

 Peninsula to the Archipelago. 



Okder XXX. SIMARUBACEiE. 



Mowers usually regular, unisexual. Sepals 3, 4, or 5. Petals as many, 

 valvate or imbricate in the bud. Stamens as many or twice as many, inserted 

 on a hypogynous disk, the filaments usually with a smaiU scale at the basd 

 (but not so in the Hongkong genera). Carpels 2 to 5, raised on the disk or 

 on a distinct stalk, free or united, with distinct or united styles. Ovules 1 or 

 3 (very rarely 4 or B) in each cell or carpel. Prait various. Seeds usually 

 solitary in each cell or carpel. Embryo slender, without or rarely with albu-' 

 men. — Trees or shrubs, always more or less bitter. Leaves alternate, without 

 stipules, usually compound, without the transparent dots of Butacece. 



An Order dispersed over the New and the Old World, but, with very few exceptions, con- 

 fined to the tropics. 



Styles distinct. Flowers clustered in long simple racemes 1. Bkucea. 



Styles united at the top. Mowers in spreading dichotomous cymes ... 2. Picrasma, 



1. BRTJCEA, Mm. 



Sepals 4. Petals 4, valvate. Stamens 4, without any scale, inserted on a 

 4-lobed disk, semiabortive in the female flowers. Cai-pels 4, distinct, with 

 distinct linear recurved styles, and 1 ovule in each, abortive or rudimentary in 

 the male flowei-s. Drupes small. Seed suspended. Embryo straight, in a 

 thin albumen. — Trees, with pinnate leaves. Flowers very small, in little clus- 

 ters or cymes, along otherwise simple axillary peduncles. 



A small genus, dispersed over tropical Asia and Africa. 



1. B. sumatr ana, iSoaii. ; Flanch. in Lond. Journ. Bot. ■?. 575. A 

 shrub or tree. Leaves pinnate, 1 to 1^ feet long ; the common petiole as well 

 as the branches and peduncles covered with a soft close yellowish tomentum. 

 Leaflets 5 to 11, ovate-lanceolate, acuminate, about 3 in. long, coarsely toothed, 

 often oblique at the base, softly pubescent or villous, especially underneath, or 

 rarely nearly glabrous. Elowers very small, purple, in little cymes or clusters 

 along the common peduncle, forming slender inteiTupted axillary racemes 6 

 to 10 in. long in the males, not half so long in the females. Petals minute, 

 4inear. , Drupes ovoid, about 3 lines long.
