THE GESNERACE^ OF THE MALAY PENINSULA. 77 



Species 2, one Burmese, one Malayan. 

 P. speciosa, Ridl., Journ. Linn. Soc, XXXII, p. 522. 



A shrub 1 or 2 feet tall, stems white tomentose. 

 Leaves in distant pairs lanceolate acuminate 6 inches 

 long lj inch wide, above glabrous, beneath white arach- 

 noid, petiole 1 inch long. Peduncle stout lateral erect 

 nearly a foot tall. Flowers sessile scattered. Bracts 

 ovate lanceolate 1 inch long white arachnoid. Calyx of 

 three sepals connate ovate oblong woolly | inch long. 

 Corolla an inch long blue, tube broad, lobes 3 two oblong 

 truncate, the third much broader. Stamens short not 

 longer than the ovary. Style long woolly. Capsule 1 

 inch long lanceolate cylindric acuminate woolly. 



Lankawi. Common on limestone rocks on the small 

 islands. (Curtis 25G4). 



Endemic. 



10. Boeica, Clarke. 



Herbs or half shrubby plants with the habit of Boea. 

 Leaves oblong elliptic or lanceolate more or less tomentose or 

 hairy. Inflorescence racemose or panicled, axillary. Flowers 

 small lilac or white. Calyx 5 lid. Corolla tube very short, 

 lobes subequal, rounded. Stamens 4, filaments very short, 

 anthers rounded connivent. Style curved larger than the sta- 

 mens. Capsule linear cylindric. 



Species 4 or 5, Assam, Burma and Malay Peninsula. 



Most of the few described species are based on flowerless 

 specimens, and are all very similar, and closely resemble Boea 

 divaricata in habit but the capsule is straight and not twisted. 

 The type species however (B.jilifonnis Clarke) has 4 stamens 

 instead of two. 



The Malayan one described below, differs from these in 

 habit, and I have seen no fruit, but there is no other genus to 

 which it can be referred on account of its four very short sta- 

 mens arranged in a circle round the pistil. The only other 

 genus allied to it is Platystemma. a Himalayan plant with dis- 

 tinctly two-lipped flowers.
