 straofo-lino- shrub, with leaves from six to twelve or more 

 inches long. Panicles composed of numerous alternate in- 

 curved divisions, crowded with innumerable, sessile, female 

 flowers on their opposite margins only.

Rami, the Malay name in the Island of Pulo Pinang. 



A native of the Island of Sumatra, where it is cultivated 

 for its bark, which abounds in fibres of very great strength 

 and fineness. In the Botanic garden where it has lately been 

 introduced, with the view of obtaining its valuable fibres, it 

 grows very luxuriantly, and blossoms about the close of the 

 rainy season. We have now had it five years in the garden, 

 the roots of the original plants, as well as of their progeny, 

 are becoming daily extended, and continue healthy and vi- 

 gorous, throwing up numerous shoots, as often as they are cut 

 down for the fibres of their bark, which may be done about 

 four or even five times every year, if the soil is good and care 

 taken of the plants, viz. if kept clean of weeds, and watered 

 when the weather is so dry as for the soil to require irrigation, 

 and carefully drained when too wet. 



The plant is as readily cultivated from cuttings, as the 

 Willow, which is fortunate, as 1 have never yet found it pro- 

 duce fertile seed. 



Stems, when suflTered to remain, they become stout, and 

 ligneous, and then covered with brown, somewhat scabrous 

 bark. Branches many, spreading considerably, the ligneous 

 parts with bark like the stems; the tender parts hairy. Leaves 

 alternate, long-petioled, cordate, hairy, and a little hoary un- 

 derneath, three-nerved ; about six inches long, by four broad.
