Flora of the Malaijan rcninsida. 459 



both surfaces olivaceous brown, the lower the paler ; margin slightly 

 recurved ; 5 to 7"5 in. long, 3 to 4 in. broad ; midrib slender, prominent 

 beneath ; main nerves 8 to 10 pairs, the lowest pair close to the margin, 

 those succeeding gradually further apart to above the middle, at an 

 angle of 60° to 70° with the midrib, curving upwards to anastomose 

 near the margin ; secondary nerves none ; reticulations transverse, 

 distant, oblique ; petiole 1 to 1-25 in. long, slender, bordered above by 

 the decurrent margins of the blade. Cymes in axillary, corymbose, 

 puberulous panicles ; peduncle slender, 1'5 in. long, flattened ; branches 

 few, also flattened but shorter ; bracteoles ovate, acute ; pedicels -1 to 

 •2 in. long, slender; buds ovoid, acute ; flow^ers yellowish-white. Calyx- 

 tube short ; lobes triangular-ovate, "075 in. long, bluntly acuminate, 

 ciliate, each with a broad short very thin scale nearly equalling the 

 base within. Corolla-iuhQ campanulate, not at all constricted, "3 in. 

 long ; lobes as long as tube, ovate-acute, the tip entire or notched, 

 pubescent without, glabrous within, except the shaggy-villous ring at 

 the insertion of the filaments. Stamens half-exsert, inserted a little 

 below the top of the tube ; filaments long, shaggy-villous, curved 

 inwards to meet and then upwards but scarcely spiral ; anthers long, 

 sagittate, the spurs much incurved, the tip membranous-apiculate. 

 D^'s A; cylindrical, entire or slightly undulately lobed, -06 in. high, glabrous, 

 fully enclosing the carpels. Carpels rounded, glabrous, at first connate, 

 afterwards separating ; style slender, conical above ; stigma conical, with 

 a spreading ring below and short often bifid tip. Fruit unknown. 

 Penang : at the Waterfall, Curtis. 



Curtis says this is a rare plant. It differs from the other species in the not con- 

 stricted campanulate corolla-tube, the very broad scale at the base of the calyx within, 

 and the entire cylindrical disk. When the fruit is known it may perhaps be found to 

 require a new genus. 



16. Vallaeis, Burm. 

 Climbing or erect shrubs, or trees. Leaves opposite, minutely 

 dotted. Flowers white, in axillary fascicles or in dichotomous pseudo- 

 axillary cymes. Calyx 5-partite, glandular or not within ; lobes narrow. 

 Corolla hypocrateriform or subrotate ; throat naked ; tube short ; lobes 

 broad, contorted, overlapping to the right. Stamens inserted at the top 

 of the tube of the corolla, partly exsert ; filaments short ; anthers 

 sagittate, acuminate, conniving in a cone around and adherent to the 

 stigma; the connective furnished with a large or small dorsal gland; 

 cells with rigid basal spurs. Disk annular or cupular, with 5 lobes or 

 scales. Ovary of 2 carpels, which are at first connate ; ovules many in 

 each carpel ; style filiform ; stigma thick, obscurely annular at base, 

 often 2-lobed at the tip. Fruit oblong, acuminate, separating into 2
