The Polygonaceous genus Muehlenbeckia includes some 
fifteen species, widely spread in the Southern Hemisphere 
from Australia and New Zealand through Polynesia to 
extra-tropical and Andine South America. They vary 
much in habit, some of them being climbers which much 
resemble species of Convolvulus, while one has flattened 
branches‘and has much the appearance of certain species of 
Acacia. Four of these Muehlenbeckias have been introduced 
_to gardens in this country and two of them have already 
been figured in this work ; VM adpressa, Meisn., as Polygonum 
adpressum, Labill., at t. 3145, and I platyclados, Meisn., as 
Coccoloba platyclada, F. Muell., at t. 5832. The species now 
figured, which is a well-known plant in gardens in the 
Aveusr, 1912.
