branches diverge and the shortest face one another. The whole 
would create the impression of antlers if the shorter main branch 
were not spirally bent over to the other side and from there 
returned to the original plane. By virtue of this spiral bend 
this whole portion does not rise as much as the other one, the 
latter protruding 60c.M. beyond the point of bifurcation, the 
former no more than 40c¢.M. (Fig. 42). 
Fasciation is, as appears from these beautiful specimens, no- 
thing but an introduction to dichotomy to be extended to 
polytomy or not. The conception of a primitive compound 
growing point has to be given up as incompatible with mere 
observation. Anthurium (see p. 21) shows exactly the same thing.

Habitat India, Sunda-Islands, Moluccas. 
A male catkin fasciates and bifurcates at top. Another male 
catkin is divided into a very great number of fasciating branch- 
lets which bend and recurve so as to form a clew which, how- 
ever, appears to be compressed to an irregular oval of 2 ¢.M. x 
1.6 ¢.M. (fig. 43). se |

Some flowers show phyllody of the calyx of which the lobes 
are pinnatifid and have a length of about 1 c.M. They are con- 
nected at the base forming a short campanulate tube which is 
densely hairy, thus being different from the sepals proper. 
Corolla absent, only a few stamens visible, drupes probably dry. 
It should be noted that in various species of Rubus registered 
by Prnzic, phyllody of the calyx has been observed ').
