One of the many good Swan River plants raised by Messrs. 
Lucombe, Pince, and Co., Exeter Nursery, from seeds received 
from Mr. Drummond. It is new to Dr. Meisner, as he recently 
informed us, and has no place in the ‘ Plante Preissiane. Per- 
haps its nearest affinity is with P. fincloria, Meisn., though the 
leaves do not change to the very peculiar green described as 
characteristic of that species, and it wants several other distin- 
guishing marks. It bears the number 426 in Mr. Drummond's 
Swan River specimens in my Herbarium. It is a highly in- 
teresting addition to our greenhouse plants, easy of culture, and 
free to blossom in the summer months. : 
Descr. Shrub two to three feet high, somewhat simple, or 
fastigiately branched ; dranches erect, glabrous, rather robust 
(for a Pimelea), reddish below, green above, terete, leafy up to the 
involucre. Leaves opposite, glabrous, the upper ones, especially,
