Bengal

If AB = 100

then CD = 172.7

German

If AB = 100

CD = 133.8

Austral

If AB = 100

CD = 133.8 147.3

The absolute lengths of the leaves cannot be compared as the germans seem small specimens

The following are the proportionate dimensions in the 3 vars

Taking the length of the leaf at 100

[sketch] A B C D

Bengal AB/CD = 11/19 =. 58/100. 100

German [ditto] = 65/87 =. 748/100

Austral [ditto] 19/28 = .68

Thus the Australian is intermediate between the others in this respect

Therefore CD being large in proportion to AB cannot be a character of the Bengal-Austr: group

All these appear to agree in having the same kind of glands, bif quadrifids, & external bifid papillæ. I think there is no marked difference between the Germans & the others in the aggregation of glands about midrib

Spines Filaments surrounding the leaf in the Australian specimens are mistake about twice the length of the leaf abt 92/44?

In the Bengals var they are about in the propn of avg bear to the length of the leaf about the proportion proportion of 78/44? a little less

In the German — according to Cohn's picture about 7/4 = 77/44.

Therefore length of filaments is not a character of Bengal-Austr: group

The Bengal & Australian specimens agree in the having filaments being which are relatively thin when compared with the Germans. Also in the filaments being much more spiny & having the double spines at the end of the filament much more distinct.) (They also agree in the spines at on the infolded edges of the leaves being not so broad at their bases in proportion to their height as in the Germans are. And in the alternation of longs & shorts being more marked than in the Germans— The end of the midrib ending in more than one spine is not characteristic of the Bengal-Austr group
