This species is doiibtfullj referred to Gyathocalijx by its authors, and 

 chiefly oa the ground that the petals, although valvate at the base, are 

 slightly imbricate above. An exainiuatiou of the large number of 

 specimens sent from Perak by the Calcutta Botanic Garden Collector 

 enables me to state that in bud the petals are truly valvate, but that as 

 they develope they undoubtedly overlap. The anthers, ovaries and 

 and ripe fruit appear to me to be those of Cyathocalyx ; and in habit 

 and general appearance of its leaves this plant agrees with the other 

 species above described. In addition to the species above described, thei e 

 are, in the Calcutta Herbarium, fruiting specimens from Perak of a small 

 tree which is apparently a fourth species of Cyathocalyx. The leaves 

 of this are oblong-lanceolate to oblong-ovate, 8- to 10-nerved, glabrous 

 above and puberulous beneath; and the ripe carpels are in pairs, ovoid* 

 puberulous, about 1"5 in. long. None of the specimens has any trace of 

 flower. 



7. Artabotrts, R. Brown. 

 Sarraentose or scandent shrubs. Leaves shining. Flowers solitary 

 or fascicled, generally on woody, usually hooked, recurved branches (pe- 

 duncles). Sepals 3, valvate. Petals 6, 2-seriate, bases concave connivent ; 

 limb spreading, flat, sub-terete or clavate. Stamens oblong or cuneate ; 

 connective truncate or produced ; anther-cells dorsal. Torus flat or con- 

 vex. Ovaries few or many ; style oblong or columnar ; ovules 2, erect, 

 collateral. Bipe carpels berried. — Distrib. Tropical Africa and Eastern 

 Asia ; described species about 32. 



This genus is at once distinguished by the curious hooked flower- 

 peduncles. The petals are thick and mostly narrow, concave and closely 

 connivent at the base, while the limb is spreading. The habit of all is 

 scandent. Besides those described below, there are in the Calcutta 

 Herbarium impei'feot materials of five undescribed species from Perak, 

 and of one from the Andaman Islands.
