not reniform — there are no rudiments of the second pair 

 visible), make the plant very distinct, and these two species 

 may well form a distinct section, if not a genus.] 



*I34. [DiDYMOCARFUS FLAVOBRUNNEA, Var. MONTANA. 



Stem woody, 10 inches tall or less, closely covered with 

 short dense hairs. Leaves lanceolate-acuminate, base narrow- 

 ed and decurrent on the petiole, margin dentate, herbaceous, 

 sprinkled with hairs above, densely velvety hairy beneath, 

 nerves 10 pairs, 6 inches long, 2 inches wide; petiole velvety, | 

 inch long. Scape 6 to 10 inches long, velvety, haiiy. Flowers 

 6 or 7, crowded at the tip. Bracts lanceolate-acuminate, long, 

 hairy. Pedicels ^ inch long, hairy. Calyx-lobes lanceolate- 

 acuminate, hairy. Corolla half an inch long; tube cylindric, 

 dilated a little at the top, maroon-red; lobes rounded, ^ inch 

 long, yellow with broad maroon streaks. Capsule linear, 

 acuminate, glabrous, an inch long. 



Wray's Camp, at 3,300 feet. 



This differs from typical D. fiavobrnnnea, Ridl., of the 

 lower part of the Tahan, in its greater size, more softly woolly 

 leaves, and in the different colouring of the corolla, which 

 is barred with broad bands of red-brown instead of a few 

 streaks.] 



135. [DiDYMOCARPUS GRANDIFLORA, n Sp, 



Stem elongate, a foot long, olive-green, woody, pubescent 

 in the young part. Leaves opposite, in pairs three-quarters of 

 an inch apart, oblanceolate, obovate or lanceolate, 1-2 inches 

 long, obtuse or shortly cuspidate, base cuneate, glabrescent, 

 with a few scattered pale hairs on the upper surface, beneath 

 paler ; nerves elevated, 3-4 pairs ; petiole half an inch long, 

 hairy. Pedicel ^ inch long, purple, glandular, hairy, axillary 

 from one of the lower leaves. Bracts lanceolate-acuminate. 

 Sepals lanceolate-acuminate, both glandular, hairy, green. 

 Corolla 2 inches long; tube glandular-pubescent, narrowed at 

 the base, then dilate, trumpet-shaped ; lobes broad, rounded, 

 all purple; limb over an inch across, irregular,' distinctly 

 bilobed; median lobe of the lower lip larger than the side- 

 lobes; a yellow, oblong, two-horned patch on the centre of the 

 mouth of the tube, the rest violet-purple. Stamens 2, white ; 

 filaments long, slender, rising from the lower part of the tube 

 to the mouth ; anthers connivent. Style slender. Stigma 

 circular. 



In forest by the stream below Wray's Camp, Tahan. 

 Rare. I could only find one flowering plant. In habit this 

 certainly suggests a Chirita near C. elata, but the character of 

 this genus, the bifid stigma, is wanting.] 



136. Parabcea leucocodon, n. sp. 



Stem rather stout, woody, simple or often branched, 8 

 inches to over a foot tall; bark corky white; young parts 

 hairy. Leaves numerous, at the tips of the branches, oblan- 

 ceolate, narrowed at the base,' subacute at the tip, 5J inches 

 long, 2 inches wide, thick, rather fleshy, dull dark green above.
