Studies in Teratology

From Mr. J. J. Smith (Java) I received three remarkable specimens of the above plant, which he collected in the Botanical Gardens August 1905. One of these specimens showed a series of ligulate florets turned downwards and altogether normal, next a zone, 2 cM. wide, of tubular proliferous florets and finally a great number of normal tubular florets. In the first place I wish to say a few words about the proliferous florets. For clearness’ sake it should be mentioned that the normal tubular florets do not show much peculiarity: from fig. 1 it appears that the style is orbiculate at its base and bifurcates at the top into two stigmas covered with rather bristly hairlets.
