Trunk short: lvs. 2-4 ft. long: pinnae with mostly longitudinal insertion, flat, straight or slightly falcate, to 8 or 10 in. long, slightly contracted and callous at base, lower margin slightly decurrent, marked on underside with parallel longitudinal veins: male cones 6-10 in. long, with much flattened scales; female cones usually shorter and thicker than the males, the scales with incurved short point.

Paulo-Guilielmi, but with a glabrous trunk and more terete rachis. M. corallipes, Hook, f., has the callous base of the pinnae bright red. B.M. 5943. G.Z. 21, p. 170. |
