A Manual of the Gymnosperms ( Ever-Greens ) of Iowa, Both Native and Cultivated

Abstract

Trees or shrubs with needle-shaped or scale-like lvs, or with broad 2-lobed fork-veined lvs. The pollen falls directly upon the ovule or young seed; there is therefore no stigma or ovary. Wood close grained, without ducts (pores); soft woods. Stam. fl. Cone-like or catkin-like, short-lived. Seeds various, with fleshy endospern. Cambium in stems and roots, forming rings of wood
