** Calyx-limb small, funnel-shaped, limb with short teeth, corolla glabrous 
or pubescent (not shaggy). 
3. U. attenuata, Korth. in Verh. Nat. Gesch. Bot. 170, t. 34; branches 
4-angled puberulous, leaves elliptic obtusely acuminate shining above puberu- 
lous beneath, flowers shortly pedicelled, calyx-teeth very short obtuse, corolla 
} in. silky, tube very slender. U. sclerophylla, Deless. Ic, Select. iii. t. 81, not 
of Roxburgh. U. Gambier, Wall. Cat. 6103 C. in part. 
Prnane, Phillips. Srxcarorr, Wallich. Texasserim, Helfer.—DisrRiv. Sumatra. 
Branches nearly glabrous. Leaves 4-6 by 2-3} in., firm, base rounded; petiole 
1-3 in.; nerves about 8 pair, very obliquely ascending, strong, with transverse veins, 
axils with tufts of hair. Peduncles 1-9 in. Heads 14 in. diam.; pedicels very short, 
elongating to 4 in, in fruit and calyx rufous-tomentose. Capsules (unripe) Z in. 
4. U. ovata, Br. in Wall. Cat. 6112, in part; 6103 D. (U. Gambier) and 
6107 in part (U. macrophylla); branches glabrous, leaves petioled oblong 
obtusely acuminate glabrous and ashy beneath, peduncles long stout straight 
axillary and in terminal panicles bracteate above the middle, flowers sessile, 
calyx-lobes ovate acute, corolla silky. 
SINGAPORE, St nr, and ‘ Hp. Fintayson,’ Wallich. 
Foliage identical with that of U. canescens, Korth., but nerves usually 8 pair, 
always without tufts of hairs in the axils; and the peduneles long and stout, 13-2 in., 
with the bract-scar 4 in. below the head, and the silky calyx-lobes ovate and acute ; 
the heads also are larger, and the corollas more silky. It differs from a Philippine 
Island plant of Cuming (n. 1470, 1503) in the calyx-lobes very short and ovate, not 
linear or subelavate. Of Wallich’s Herbarium specimens (the only ones I have seen) 
one is from Singapore, on sheet 6112, with U. Gambier; another is on a sheet by 
itself, marked ‘6103 D. U. Gambier, Herb. Finlayson’ (probably from Siam, where 
Finlayson collected); the third, also on a sheet by itself, is marked ‘6107. U. sessi- 
lifolia, Roxb. Ic. pict. Sylhet.’ The latter is probably an erroneous habitat. There 
is a very similar plant in Maingay’s herbarium from Penang (U. sclerophylla, Kew 
Distrib. 828), with the leaves slightly scabrid beneath. 
5. U. canescens, Korth. Verh. Nat. Gesch. Bot. 172; branches glabrous 
or puberulous, leaves petioled oblong obtusely caudate-acuminate glabrous 
ashy beneath, peduncles very short bracteate near the base, calyx densely 
tomentose lobes rounded, corolla pubescent. 
Maracca or Penanc, Maingay (Kew Distrib. 1768, in part). 
have very imperfect specimens of this mixed with U. ovata, Br.; they precisely 
accord with others from Sumatra, collected by Korthals. These differ from all 
described species by the glabrous foliage, glaucous beneath, together with the very 
short curved peduncles, bracteate towards the base. Leaves 4-6 by 13-22 in., rather 
membran us; nerves slender, 7 pair; petiole 3-3 in. Pedwncle A in., decurved ; 
bracts ovate, acute, pubescent. Heads 1} in. diam.; flowers at first sessile, pedicelled 
later.— Identical in foliage with ovata, Br., and a Philippine Island species (Cuming, 
1470, 1503), differing in the peduncle and calyx from both. 
4 9. U. pteropoda, Mig. Fl. Ind. Bot. ii. 943; branches 4-angled glabrous, 
leves large very coriaceous very broadly elliptic or ovate obtuse narrowed into 
tl short winged petiole quite glabrous, peduncles short stout all axillary brac- 
te above the middle, heads large, flowers sessile, calyx-teeth obtuse.

A very distinct species (the Indian specimens are in fruit only) of a pale colour. 
Branches rather slender. Leaves 6-8 by 4-5 in., not shining above or beneath, point
