Vitis spec. On a branch are found, alternating with normal 
ones, various leaves of which the midrib is divided into two 
from the base. They are therefore bifid; designating the under- 
most leaf with 1, we have: n° | bipartite half-way down, 
apices subequal, n° 2 normal, n° 3 divided as far as }, apices 
nearly equal, n° 4 divided as far as 3, apices slightly unequal, 
n° 5 fallen off, n° 6 normal, n° 7 bipartite as far as 4, apices 
almost equal, n° 8 normal, n° 9 with a slight notch on one 
side of the leaf, n° 10 emarginate as far as ¢, apices very 
unequal, the following leaves normal ’). 
Lantana spec. (fam. Verbenaceae). On a little branch, one of 
the two leaves of a whorl has its midrib, beginning from the 
base, divided into two, the lamina being incised as far as } 
from the top, the two pairs of leaves between which the de- 
Viation is found, are normal; the fourth whorl, a very young 
one, is triple. This species has often tri-verticillate leaves. 
Gonocaryum pyrospermum (fam. Olacineae). Leaf with a midrib 
split up into two from base of blade. Two apices. Petiole groo- 
ved at back, close to the blade only. 
Callicarpa spec. (fam. Verbenaceae). One leaf of a pair is 
divided into two, so as to form two quite separate blades of 
normal shape and two petioles loosely cohering. 
Acrostichum ? spec. (Filices) shows various bifid leaves. 
Asplenium nidus (Filices) growing wild in the Government 
Gardens shows in a young specimen various degrees of fissure 
of the apex. 
Atalanta monophylla (fam. Aurantiaceae). A leaf with a broad 
flat petiole, a midrib from the base divided into two, and an 
apex slightly notched. 
§ 3. Transformation into pitchers. 
In the third place we mention certain cases of transforma- 
tion of leaves into pitchers. The division above described of a - 
1) In March 1895 the same specimen was found to have produced a similar 
branch with divided leaves.
