6. Unona Dastmaschala, Blume Fl. Jav. Anon. 55, t. 27. An 

 erect or sarmentose shrub : young branches sometimes glabrous from 

 the beginning, but usually at first softly rufous-pubescent and sometimes 

 permanently so. Leaves thinly coriaceous, elliptic-oblong, oblong, or 

 oblong-lanceolate or oblanceolate, acute or shortly acuminate, the base 

 rounded or narrowed ; upper surface glabrous ; the lower sub-glaucous, 

 glabrous or sometimes puberulous on the midrib and nerves ; length 4"5 

 to 8 - 5 in., breadth 15 to 3 in., petiole about "1 in. Flowers pedunculate, 

 solitary, axillary, pendulous, l - 5 to 3 in. long; peduncles 1 "25 to 1" 75 

 in. (longer in fruit), minutely bracteolate at the very base. Sepals 

 fleshy, very short, broadly triangular, pubescent, reflexed. Petals fleshy, 

 varying from ovate-acute to lanceolate-acuminate, concave and (in the 

 narrower forms) expanded at the base, with a constriction between the 

 claw and limb ; the edges united when young, adpressed-puberulous but 

 ultimately glabrous. Anthers with the connective expanded at the apex 

 and oblique. Ovaries densely villous ; the stigma narrow, glabrous. 

 Pipe carpels numerous, shortly stalked, moniliform, pubescent to glabrous, 

 the joints oval, about "35 long. Seeds oval, smooth, the albumen with 

 fibrous processes. A. DC. Mem. Anon. 28; Wall. Cat. 6421; Hook. fil. 

 and Thorns. PL Ind. 135 ; Miq. Fl. Ind. Bat. I, Pt. 2, 42 ; Kurz Fl.

 Sumatra, Java. 



Var. Blumei, Hook. fil. ; branches glabrous ; leaves pale-yellowish 

 or grey beneath, glabrous or nearly so. Wall. Cat. 6420 B. {U. discolor.) 



Var. Wallichi, Hook. fil. ; branches brown-tomentose ; lower surfaces 

 of leaves glaucous and tinged with purple. 



This species, in the absence of the inner row of petals and in other 

 respects, resembles M. longiflora, Roxb. ; but the outer petals are neither 

 so long nor so narrow, and there appear always to be three of them, and 

 not often only two as in M. longiflora. The peduncles are moreover 

 shorter. The two species, however, are closely allied. In open, exposed 

 situations this is a non-scandent bush ; but under the shade of trees, it 

 often developes into a climber, — a habit which it shares with many species 

 of this family. Blume's figure of this plant (quoted above) is inaccurate 

 as respects the flowers and fruit. 



7. Unona Wrayi, Hemsl. in Hook. Ic. Plant t. 1553. A tree : 

 young branches slender, tawny-tomentose. Leaves thickly membran- 

 ous, elliptic-oblong, shortly acuminate, often obtuse (from the breaking 

 off of the acumen), slightly narrowed to the rounded base ; upper 

 surface glabrous except the puberulous midrib ; lower much reticulate,
