shaped • 1 in. long with 5 minute teeth. Corolla tube • 5 in. 

 long, glabrous within lobes linear undulate, a strong rib 

 outside and 2 inside, -5 in. long. Stamens 5 in a slightly 

 dilate portion of tube below the mouth linear, apiculate. 

 Style long exsert half as long as corolla-lobes. Fruit unripe, 

 globose, narrowed to the persistent calyx. Tasan : White ; 

 tree ; 6940. Mergui (Griffith) . This together with P. 

 malayana as well as probably several other species was con- 

 fused by Hooker in the Flora of British India with the 

 very distinct P. alhidiflora, Thw., of Ceylon. P. Griffithii 

 differs from the Malay Peninsula, P. malayana, in the very 

 short petiole and pedicels, and much longer calyx.

136. Psychotria auriculata, sp. nov. 



Shrub 6 to 8 ft. tall, glabrous. Leaves oblanceolate, 

 shortly blunt, acuminate sessile, narrowed to a blunt

Tliis belongs to the stiff-leaved pale group Griffithiiy 

 etc., but has sessUe auricled leaves. 



137. Psychotria ? lasiocephala, sp. nov. 



Hauy, woody shrub. Leaves thin, coriacfeous elhptic 

 lanceolate, grey, glabrous above, closely velvety hairy 

 beneath ; nerves 12 pairs, 6 in. long, 1-75 in. wide ; petiole

 and fringed with long purple hairs. CoroUa very short, 

 glabrous, lobes oblong. Stamens 5. Style very short, entire. 

 Tapli : Inflorescence green ; shrub. 



The flowers are all very young, so it is difficult to be 

 sure it is a Psychotria.
