Description

"This species, which resembles D. spinulosum in overall habit, differs from it in having smooth-edged leaflets ... though the petiole is spinous. It is also unique in the greenish-gray color and abruptly acuminate shape of the female cone, and in having ovules with a chalazal appendix (i.e., an outgrowth opposite the micropyle)" (Norstog and Nichols 1997).

Distribution and Ecology

Honduras: Department of Olancho: in a dry, rocky canyon, where first discovered; also in Nicaragua (Norstog and Nichols 1997).
