to endorse. The cross-hatched ovals indicate flowerstalks, with 
very rare exceptions producing normal flowers. 
The same plant shows one more phenomenon, which, though, 
hardly in its place here, may be briefly referred to for the sake 
of completeness. 
In order to facilitate a close examination of the shoot de- 
scribed Mr. Smith had been obliged to cut off other developing 
leafbuds. When there had gradually appeared fresh ones, a 
flowerstalk became visible which was united to the underside 
of one of the topmost leaves (fig. 26). This peduncle together 
with the leaf was bent firmly downward (comp. fig. 27, dark 
= peduncle, light = leaf) and measured about 2 dM. from the 
ground. The leaf (destitute of apex) coalesced by its midrib 
with the stem over a length of about 1} dM. The lateral 
halves of the leaf formed an acute angle, the peduncle is 
indented along the line of coalescence. This groove is replaced 
on the free part of the flowerstalk by a flat ribbon which on 
both sides marked off by a slit,. tapers upward. 
The free portion of the leaf is flat with two longitudinal 
thickenings (midribs) close to each other; at the point of union 
these ribs bend themselves into the edges of the aforesaid 
ribbon of the peduncle. The leaf is slightly swollen out at the 
point of divergence (a). The flowers appear normal. 
Fasciations were further observed in Ce/astrus paniculatus and 
C. alpestris (fam. Celastrineae), in both cases on boughs, and 
to a slight degree on a slender pendent climbing branch of 
Combretum Wightianum, a member of the tropical Combretaceae 
family.

Saccolabium Blumei. Bifurcated roots of this Orchid were se- 
veral times observed on a specimen introduced into the Buiten- 
zorg Garden from the country. This case is undoubtedly to be 
classed with root-fasciations. In the German translation of
