** Calyx-limb small, funnel-shaped^ limb with short teeth) corolla glabrous 

 or pubescent (not shaggy}. 



3. IT. attenuata, Korth. in Verh. Nat. Gesch. Sot. 170, t. 34 ; branches 

 4-angled puberiilous, leaves elliptic obtusely acuminate shining above pubem- 

 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. 



PENANG, Phillips. SINGAPORE, Wallich. TENASSERIM, Heifer. DISTRIB. Sumatra. 



Branches nearly glabrous. Leaves 4-6 by 2-3 in., firm, base rounded ; petiole 

 i-f in. ; nerves about 8 pair, very obliquely ascending, strong, with transverse veins, 

 axils with tufts of hair. Peduncles 1-2 in. Heads 1^ in. diam. ; pedicels very short, 

 elongating to ^ in, in fruit and calyx rufous-tomentose. Capsules (unripe) f in. 



4. U. ovata, Sr. in Wall. Cat. 6112, in part; 6103 D. (U. Gambier} and 

 6107 in part ( U. macrophylld) ; 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, SILHET, and ' HB. FINLAYSON,' Wallich. 



Foliage identical with that of U. canescens, Korth., but nerves usually 8 pair, 

 always without tufts of hairs in the axils ; and the peduncles long and stout, 1| 2 in., 

 with the bract-scar 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 subclavate. Of "Wallich s Herbarium specimens (the only ones I have seen) 

 one is from Singapore, on sheet 6^112, with U. Gambier; another is on a sheet by 

 itself, marked '6103D. U. Gambier, Herb. Finlayson' (probably from Siam, where 

 Finlayson collected) ; the third, also on a sheet by itself, is marked ' 6107. U. sessi- 

 lifolia, Eoxb. Ic. pict. Sylhet.' The latter is probably an erroneous habitat. There 

 is a very similar plant rn Maingay's herbarium from Penang (U. sclerophylla, Kew 

 Distrib. 828), with the leaves slightly scabrid beneath. 



5. TT. canescens, Korth. Verh. Nat. Gesch. Sot. 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. 



MALACCA or PEXANG, Maingay (Kew Distrib. 1768, in part}. 



I 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 l^-2f in., rather 

 membranous ; nerves slender, 7 pair ; petiole -f in. Peduncle $ 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. 



6. IT. pteropoda, Miq. Fl. Ind. Sot. ii. 343 ; branches 4-angled glabrous, 

 leaves large very coriaceous very broadly elliptic or ovate obtuse narrowed into 

 the short winged petiole quite glabrous, peduncles short stout all axillary brac- 

 teate above the middle, heads large, flowers sessile, calyx-teeth obtuse. 



PENANG, Phillips. MALACCA, Maingay (Kew Distrib. n. 829). DISTRIB. Sumatra, 

 Borneo. 



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 

 suddenly contracted but obtuse ; nerves 6 or 7 pair, very strong beneath, arched.
