86 D. Prain — Some additional species of Convolvulacese. [No. ^, 



Malay Peninsula : Perak, at 2,000— 2,500 ft. elev., Ktmstlern. 7337 ! 

 A very large climber, " 100-150 ft. long, 2-3 in. diam." (Kunstler). Leaves 2^-5 in. 

 by 1-2 in., shining, often blistered beneath ; lateral nerves 5-6 pairs with a distinct 

 marginal nerve, secondaiy veins also distinctly impressed especially beneath, petiole 

 ^ in., or less. Cymes axillary 3-20-fld. peduncles and bracteolate pedicels (J in long) 

 rusty close-pubescent. Sepals orbicular, closely brown-tomentose. Corolla lobes 

 spreading 4 in., pale yellow ; interlobular portion pale-brown tomentose externally, 

 lobules ovate-oblong, margins undulate. Berry not seen. 



Allied to Erycibe coriacea, but with smaller and more coriaceous leaves, and with 

 flowers more like those of E. glomerata. The leaves when dry are of a coppery red 

 colour. 



3. Erycibe praecipua Prain ; branchlets round, quite glabrous ; 

 leaves very coriaceous, nerves obscure on botli sui-faces, long petioled, 

 narroAvly elliptic, attenuated to both ends, apex obtuse ; cymes axillary, 

 small lax few-fid. 



Penang : Government Hill, Curtis n. 911 ! 1273 ! 



A large climbing shrub, branches round. Leaves l|-3 in. by |-l-2- in., all 

 nerves quite obscure ; petiole J in., glabrous. Cymes J in. 5-8-fld., minutely ad- 

 pressed pilose, pedicels bracteolate, ^ in. Sepals orbicular, outer minutely, inner 

 densely, closely rusty pubescent. Corolla lobes very nari'ow, spreading ^ in. ; inter- 

 lobular portion rufous pubescent internally and externally ; lobules small, glabrous, 

 narrowly oblong, subacute divergent. Berry coriaceous rough, ovoid, f in. long | in, 

 across, pointed. 



This species is not easily differentiated fi'om Erycihe Maingayi — of which 

 there is no specimen at Calcutta — by the somewhat incomplete diagnosis of 

 the F. B. I, All the characters given for E. Maingayi ajiply to E. praecipua, except 

 the explicit one of ' hairy innovations ' and the implication that its secondaiy 

 nerves are distinct. E. Maingayi is, however, said to appear to be allied to E. 

 Princci — an alliance by no means marked in E, praecipua. This, coupled with the 

 fact that E. praecipua has been distributed by Mr. Curtis as E. coriacea, and that 

 Dr. Stapf informs him that the plant has been associated (though not identified) 

 with E. coriacea at Kew, assures the writer that it is distinct from E. Maingayi. 



E. coriacea is a species founded on Wall. Cat. n. 1337, from Chittagong, a plant 

 that has apparently been lost. It was seen and described by Choisy {An7i. Sc. Nat. 

 2, i, 224\ but it is not present now in the Wallichian type Herbarium, or in the 

 Herbaria at Kew and at Calcutta. But Choisy considered E. fragrans, Wall. {Cat. n. 

 1336) con-specific with E. coriacea ; whence we may infer that the flowers of E. 

 fragrans are similar to, if not identical with, those of E. coriacea. 



In E. praecipua the corolla lobes ai'e long and narrow, with small divergent 

 auriculate lobules, as in E. Griffithii, and to a lessdegi-ee in E. Stapfiana, while the 

 interlobular portion of the corolla lobes are densely pubescent within as well as 

 without. In E. fragrans the lobes are short and wide with large ovate over-lapping 

 lobules, the interlobular part of the lobes being glabrous within as iu every other 

 species of Erycihe in the Calcutta Herbarium except E. praecipua. 



Had this character been present in the lost E. coriacea, Choisy would never 

 have united with it Wallich's E. fragrans ; unless the same character is present in 

 the corolla of E. Maingayi (which has not as yet been described), this alone should 

 be sufficient to distinguish E, praecipua from all the hitherto described species of 

 Erycihe.
