This is the most striking of all the species of Mematanthus, 
known in cultivation, remarkable for the great length of the 
flower-stalks, the deep blood-colour of the corollas, the rich 
purple of the calyx-tube, and the pubescence on these latter. 
De Candolle, as observed under our Tab. 4018, JV. longipes, 
seems inclined to refer it to that species: but we agree with Dr. 
von Martius that it is “ distinctissima.” According to this last- 
mentioned author, it grows in primeval woods of Brazil, between 
Theos and the town of San Pedro de Alcantara :—there flowering 
in September, with us in the spring months, requiring a moist 
stove for its successful cultivation. We owe the possession of it 
at Kew, to Mr. Henderson of Pine Apple Place, who sent it 
under the unpublished name of WV. Morrelliana. oe
