being somewhat slenderer than the apex, whereas it is gene- 
rally the reverse. Fig. 6 represents a still younger plant more 
magnified, in which the hypocotyl is of the normal shape 
and bears a clearly perceptible seed-lobe. The stem with the 
bracts is visible, also a young inflorescence and a very short 
root (w). This root has however soon proceeded to form a 
fresh hypocotyl (hy 2), but its apex was gnawed off by some 
animal. In Fig. 7 is reproduced an adult plant at natural size 
and in fig. 1 a similar plant magnified by 2 diameters. At hy 
1 is the hypocotyl, issued from a seed from which proceeded, 
besides the two inflorescences, three roots, and at the extre- 
mity of each root was developed a hypocotyl (hy 2, 3 and 4). 
Fig. 1 shows something similar. 
Twice I found a deviation from the rule; fig. 2 is an illustra- 
tion of such an abnormal plant. From the seed there has is- 
sued a normal, only taller hypocotyl, to which there are attached 
three roots, two older and one younger. Now these former two 
had not formed any fresh hypocotyls, but again two roots, the 
_ part where they are joined to the old roots being clearly marked 
by a narrower constriction. But this phenomenon is also found 
in other epiphytic orchids. 
In fig. 1 the original hypocotyl has disappeared; on one root 
(w 1) a new young plant has been formed, but on the other 
(w 2) have developed first one hypocotyl and an other again 
on this. So I found the plant among the material I had preser- 
ved in alcohol. 
It is a pity that the climate of Buitenzorg does not seem 
to be favourable to the growth of this remarkable plant. The 
specimens transferred by myself did indeed continue alive for 
some time and they formed also some new plants wom in course ae 
of time they have all died. 
In this species of Taeniophyllum a one may chon a 
two remarkable facts concerning its growth: firstly the recur- _ se 
_ rant formation of hypocotyls at the roots-tips, and secondly, ee ee 
— formed. As ier: 2 as t am aware > neither * these facts
