404 XXXIV. CELASTRINE^. [SipJionodon . 



lines long. Testa of the seed brown ; albumen not very tliick ; cotyledons 

 broadly ovate. 



Queensland. Brisbane river, A. Cunningham* 



N. S. "Wales. Clarence river, Beckler. 



Until the flowers have been seen, this plant must remain in some measure doubtful, but 

 the habit and fruit are so neai'Iy those of S. ceJastnneus, that I have little hesitation iu re- 

 ferring it to that genus. The ovary must probably be considered as 5-cellcd with many 

 ovules in each cell, separated by spurious transverse dissepiments. 



Tribe II. HirpocuATEiE. — Stamens usnally 3 only, with a 5-merous 

 calyx and corolla, inserted on the disk itself; filaments usually incurved at 

 the base but recur\^ed under the anther, which thus opens outwards. Seeds 

 without albumen. 



Queensland. Morcton Bay, W. Hill, F, Mueller. 



W. S. VTales. Qarence river, Beckler. Tbc speeies is widely distributed over tro- 

 pical Asia. The common Indian form, figured iu Wight, Ic. t. 963, has glabrous petals, but 

 the variety with bearded petals as described by Korlhals from Borneo, and of which we have 

 specimens from Ceylon, is the same as the Australian one ; and the amount of hairiuess 

 both on the petals and ovary appears to be variable. 



Oeder XXXY. STACKHOXJSIEiE. 



Flowers regular, hermaphrodite. Calyx small, 5-lobed or 5-cleft. Petals

6. HIPPOCRATEA, Linn. / 



Calyx small, 5-cleft, Petals 5, valvate or imbricate. Stamens usually 3, 

 the filaments thick at the base, connivent round the ovary, recurved at the 

 top; anthers at first divided into 2 or 4 cells, at length confluent into 1 

 transverse cell. Disk conical or broad. Ovai*y 3-celled, style short, stigma 

 3-lobcd; ovules* 2 or more in each cell. Fruit of 3 distinct, flat, coriaceous 

 carpels, opening along the middle in 2 boat-shaped valves. Seed compressed, \ 



usually produced at the base into a wing adnate to the raphe; albumen 

 none ; embrj^o in the upper end of the seed ; cotyledons flat, connate; radicle 

 inferior.-^ Small trees or woody climbers. Leaves opposite, entire or serrate. 

 Stipules very small and deciduous. Flowers in axillary cymes or panicles. 



A large genus, widely distributed over tropical Asia, Africa, and America, the Australian 

 species beiut; one of the common Asiatic ones. It belongs to the section with comparatively 

 large flowers and valvate petals. Tlie other section common in India, including //. indica^ 

 with minute globular flowers and imbricate petals, has not yet been observed in Australia. 



1. H, obtusifolia, Roxb.; W, and Am. Frod, 104, var. barbata. A 

 tall, woody, glabrous climber. Leaves ovate, obovate, or oblong, obtuse or 

 obtusely acuminate, 2 to 4 in. long, entire, coriaceous, somewhat shining. 

 Flowers in short, loose, axillary cymes, the upper ones forming sometimes large 

 leafy tenninal panicles. Petals fully 2 lines long, lanceolate, rather thick, 

 valvate in the bud, and in the Australian specimens bearded inside above the 

 middle, the disk and ovarj^ also occasionally villous or pubescent. Ovules 6 

 to 10 in each cell of the ovary. Carpels about 2 in. long, either broadly ob- j 



long and entire or broader and emarginate at the top. — //. macrauthay Korth.
