was securely fastened, the tendril itself described 
‘similar but much smaller figures. 
This species climbs well. The tendrils after clasp- 
ing a stick become thicker and more rigid; but the 
blunt hooks do not turn and adapt themselves to the 
supporting surface, as is done in so perfect a manner 
by some Bignoniaceee and Cobxa. The tendrils of 
young plants, two or three feet in height, are only 
half the length of those borne by the same plant when 
grown taller, and they do not contract spirally after 
clasping a support, but only become slightly flexuous. 
full-sized tendrils, on the other hand, contract spirally, 
with the exception of the thick basal portion. Ten- 
drils which have caught nothing simply bend down- 
wards and inwards, like the extremities of the leaves 
of the Corydalis claviculata. But in all cases the 
petiole after a time is angularly and abruptly bent 
downwards like that of Eccremocarpus. ,
