XXX. BUKSERACE^. 377 



tralian 3-foliolate, without or rarely with stipules. Flowers small^ in racemes 

 or panicles. 



The Order is spread over most tropical regions. The two Australian genera are both 

 widely dispersed over tropical Asia, one is also in Africa, and the other in tropical America. 



Calyx 5-lobed, the disk lining the tube, with the stamens on the margin • 1. Gaeuga- 

 Calyx 3-lobed, the disk free, with the stamens outside or on the margin . 2. Canarium. 



1. GARUGA, Eoxb. 



Flowers polygamous. Calyx campanulate, 5-lobed, valvate. Petals 5, in- 

 serted above the middle of the calyx-tube, induplicate-valvate. Disk thin, 

 hning the calyx-tube. Stamens 10, inserted with the petals. Ovary 4- or 

 5-celled; styles elongated; ovules 2 in each cell. Drupe indehiscent, with 

 5 or fewer bony nuts, rugose outside. Seeds solitary in each nut ; cotyle- 

 dons folded, — Trees, Leaves pinnate. "Flowers rather large for the Order, 

 in terminal panicles. 



The genus is dispersed over tropical Asia and America ; the Australian species extends at 

 least to Timor, and is perhaps a variety of a common Asiatic one. 



L G. floribunda. Dene. Herb. Tim. Descr. 149. Branches thick, 

 luarked with the broad scars of the fallen leaves. Leaves crowaled at the ends 

 of the branches i leaflets 7 or 8 pairs, very shortly petiohdate, very obliquely 

 ovate-hinceolate, acuuiinate, 2 to 3 in. long, crenate especially on the outer 

 edge, glabrous when full grown, the conuiion petiole 8 in. to 1 ft. long, 

 shghtly pubescent or at length glabrous. Panicles broad and dense, termi- 

 nating leafless brunches, Flowers numerous, nuich smaller than in the com- 

 nion Indian G. phinata, Roxb., arranged in cymes along the last ramifications, 

 the pedicels and flowers hoaiy with a minute tomeutum. Calyx about 2 

 lilies long. Petals linear-oblong, twice as long as the calyx-lobes. Fruit not 

 seen. 



N. Australia. Port Nelson, N.AV. coast, A. Ctmnhigham, I have followed Planchon 

 (m Herb, Hook.) in referring this to the Timor species described by Decaisne, although I 

 have seen no specimens from that island. It differs from some forms of G,j)innaia, Roxb., 

 ill little besides the much smaller ilowers in a more compound panicle. 



2. CANARIUM, Linn. 



Flowers hermaphrodite or polygamous. Calyx campanulate, usually 3-lobed, 

 valvate. Petals usually 3, valvate, or slightly imbricate in the bud. Disk 

 annular, rather thick. Stamens twice as many as petals, inserted on the 

 ^ai'gin of or outside the disk. Ovary usually 3-celled; stigma sessile, capi- 

 tate, 3-lobed ; ovules 2 in each cell. Drupe ovoid or ellipsoid, often 3-auglcd, 

 the putamen l-cclled by abortion. Seed solitary; testa membranous; co- 

 tyledons folded.— Trees, with large pinnate leaves. Flowers small, in axillary 

 • panicles, 



The largest genus of the Order, dispersed over tropical Asia and especially the Indian 

 Archipelago, with a few African flpecies. The Australian one is endemic, 



1. C. australasicum, F, MuelL Frugm, iii. 15. Branches thick, 

 parked with the broad scars of fallen leaves, the young ones minutely hoary, 

 Leaflets 5 to 9, petiohdate, ovate or oval-oblong, or the lower ones nearly
