This is said by Tweedie to be a shrub 12 to 20 feet hio-h "* 

 evidently with long, slender, pendent branchlets, growin- v?rv 

 plentifully near the town of Santa Ee, on the river Parand • the 

 branchlets are slender, of a light brown colour, smooth and 

 striated. Two, three, or more leaves grow in a fascicle out of 

 each cup-shaped axillary node; they are 10 to 16 lines long 

 1 or 2 lines broad ; two or three flowers spring out of each 

 fascicle of leaves, one after another, at distant periods : the 

 peduncle is 11 or 1 line long; the smooth cup-shaped calyx is 

 of the same length, and is crowned by four equal triangular 

 teeth with ciliated margins : the corolla is contracted nea? the 

 base, IS broadly campanular above, with foui- short and broad
