LEAF FORMS OF VARIETIES OF HIBISCUS CANNABINUS. At least two varieties of the Deccan hemp are grown in Egypt, one with deeply divided, finely toothed leaves (Pis.

It does not appear that either of these Egyptian varieties has been introduced into the United States, but a third variety with digitate

It does not appear that either of these Egyptian varieties has been introduced into the United States, but a third variety with digitately parted leaf blades, not seen in Egypt but supposed to come from India, has been grown experimentally in Louisiana. (Figs. 5 and 6.). Fig. 4.—Simple-leaved Egyptian variety of Hibiscus cannabinus. (Natural size.) The variety with the dimorphic leaves is much more generally planted in Egypt, but plants with broader, undivided leaves are often found growing with the others. At Tanta, to the north of Cairo, separate plantings of the broad-leaved variety were seen. The plants seemed larger, coarser, and of a darker green color than those of the narrow-leaved type growing in the same locality. The leaves are distinctly larger and with the margins much more coarsely toothed. A tendency to the lobed form of leaf seemed to be indi- cated in this variety only by the somewhat larger teeth at the ends of the largest of the oblique veins. There may be a general corre- lation between the shape of the leaf and the size of the marginal teeth. The teeth seem to be larger in the undivided leaves of the.
