Erycibe cauliflora Hallier f. 



Habitat the East Indies. 



Coll. Aug. 1896. 



A young terminal shoot, still covered with brown woolly 

 hairs, 3.20 cM. long, shows 1.7 dM. above the lower end on 

 one side (upper side) a groove which broadening higher up 

 leads to biturcation. Only the upper half of the whole shoot 

 has been represented in the figure (68). In this our special 

 attention is drawn towards leaf d e, as being attached with 

 the one half of its petiole at the same height as leaf a and 

 with the other half on the level of leaf h. It is obvious that 

 the bifurcation was just in its beginning at the height of leaf 

 a and that on this very spot the leaf d e has originated as a 

 joint product of the two internodes that are to separate higher 

 up. As however the left internode has lengthened more intensely 

 than the right one, the base of d e has been torn up. This 

 view corresponds with the fact that the (left) internode be- 

 tween h and g is distinguished by a very strong extension 

 from the (right) internodes a—e and e—f. The left part ter- 

 minates after having produced two more leaves in a bud of 

 little development, the right one on the contrary lengthens 

 1 cM. beyond the two leaves, which it produces and which 

 are indicated in the figure with h and i. One of these, i, is 

 cup-shaped. As the whole shoot was cut off for the examina- 

 tion, its further development could not be followed. 



SCROPHULAKIACEAE. 



Penstemon ^) campanidatus Wild. 

 Habitat Mexico. 

 Coll. Dec. 1894. 



[N.B. In the normal flower the corolla tube is long and the 

 lobes of the lips short]. 



1) = Penta^femum on account of the nunaber (5) stamens differing from the ordi- 

 nary (4) number in the family of Scroplndariaceae. In our paper of 1895 we mention 

 a regular peloria of the plant; so does Pekzig II, p. 203.
