208 Take da. — Some Points in the Morphology of the 
examined shows the following sequence : the first node of the aerial stem, 
which is continuous with a rhizome, has four ‘ leaves ’, the second five, the 
third four(P), 1 the fourth five, the fifth four, the sixth four (P), 1 the seventh 
to ninth six each, the tenth four ‘ leaves one of the two stipules having 
a forked midrib (Fig. 23) ; the eleventh again bears four ‘ leaves’, and one of 
the stipules, which are smaller than the true leaves at the same node, 
has a slight indication of a double nature ; the twelfth, which is giving 
off a branch terminated with an inflorescence, has four members with the 
two stipules markedly smaller than the true leaves at the same node ; 
the thirteenth whorl, which is at the ultimate node on the stem, consists of 
two true leaves (7 to 8 mm. long), and a small but normal stipule (4 mm. 
long) on one side, and two minute stipules (2 mm. long) on the other side of 
the node. From this node three peduncles have sprung, two of which have 
at their first (and only) node two small true leaves only, stipules being com- 
pletely suppressed, while the remaining peduncle bears at its lowest node 
a pair of true leaves and a minute stipule (1 mm. long) on one side of the 
stem. Another specimen examined shows a somewhat similar feature : at 
the first and second nodes the ‘ leaves ’ have withered and are torn off ; the 
third node, which is very similar in appearance to the fifth node of the first 
specimen above described, has five ‘ leaves ’ ; the fourth node bears four 
‘ leaves ’, and one of the stipules is equal to the true leaves, while the other 
is broader and is provided with two midribs (Fig. 24) ; the fifth to seventh 
nodes are all six-membered ; the eighth node has four ‘ leaves ’, and one 
of the stipules of this whorl possesses a forked midrib, and is exactly 
the same in appearance as that delineated in Fig. 22, while the other is 
normal ; the ninth node is again four-membered but without any double 
stipule ; the tenth node is similar in every respect to the eighth node, with 
this difference, that the midrib of the double stipule is more deeply forked 
(Fig. 25) ; the eleventh (ultimate) node is also four-membered, with two 
stipules considerably smaller than the true leaves. At the ultimate node of 
another specimen the writer found two true leaves 2 and two stipules, the 
latter being much reduced in size, and one of them being provided with two 
complete midribs (Fig. 2b). 3 
As has already been mentioned above, the occurrence of double 
stipules in the case of nodes with more than four ‘ leaves ’ is very rare. 4 
The only instance the writer has found is presented by Asperula aspera 
1 The whorl has been damaged, and consequently it is very difficult to determine this point with 
absolute accuracy. 
2 One of these leaves is shown in Fig. 27 for comparison. 
3 Since this species bears flowers with a usually three-, often four-, and rarely five-lobed corolla, 
a search was made with a view to detect corolla-lobes with a forked vein. Unfortunately, the result 
has so far been negative. A propos, it may be mentioned that Galium saxatiie , Linn., also produces 
pentamerous flowers very frequently. 
i No case in which a double stipule occurs in a whorl with more than five * leaves’ has been 
observed or recorded.
