DESCRIPTIVE FLORA 
SUBKINGDOM SPERMATOPHYTA  GSxrzkpb-PrLANTS 
Plants producing flowers and seeds. A seed contains an em- 
bryo consisting of a short stem (radicle, caulicle, or hypocotyl), 
one, two, or several rudimentary leaves (cotyledons), and a term- 
inal bud (plumule). | 
Crass 1. GYMNOSPERMAE  Coxr-PLANTS 
Carpel or pistil represented by a scale on the face of which the 
ovules are borne, and on which the naked seeds mature. 
Ordek CYCADALES — CYCADAL ORDER 
Palm-like or fern-like plants. Leaves in a crown: blades pinnate. 
Flowers in cones of approximate scales or on less modified leaves. Stam- 
inate cone with scales bearing several pollen-saes. Ovulate cone with two 
or more ovules on each scale. Seed drupe-like or nut-like. 
Faminy d. CYCADACEAE — Saco-patm FAMILY 
Dioecious plants with subterranean or aérial stems. Leaves clustered:
