(Plate IX.) 



In your Paper on the "]Movcments and Habits of Climbing- 

 Plants," you say that you have seen no tendrils formed by the 

 modification of brandies, and you even seem to entertain some 

 doubt Avhetber sucb tendrils exist. In the genus Stnjchios, the 

 tendrils are called by Endlichcr ramuli cirriformcs, and I have 

 now sati:<fied myself that they really are of this nature. On the 

 brauclies of upright shoots of a Strj/cJinos which grows here, the 

 tendrils are disposed in a very regular manner. On the branches, 

 the leaves of the first, third, fifth, &c. pairs are horizontal, those of 

 the second, fourth, and sixth pairs are vertical in relation to the main 

 axis ; and it is from the angles of every under leaf of these latter 

 pairs that the tendrils spring. Xow, on the points conimouly 

 occupied by tendrils, true branches are sometimes developed. 

 The leaves from the angles of which the tendrils spring are often 

 much reduced in size, while in other cases they are but little or 

 not at all changed. Each tendril bears near its tip a pair of rudi- 

 mentary leaves; and whilst very young the tendrils are straight, 

 but soon become curved downwards and rolled into H hebx, 

 whether they have clasped a support or not. This StrycTinos^ is a 

 very inefficient climber; the short stiff tendrils but rarely catph 

 anything.
