FLORA OF MIAMI. 



Subkingdom SPERMATOPHYTA. SEED PLANTS. 

 Plants producing flowers and seeds. A seed contains an embryo 

 consisting of a short stem (radicle or caulicle), one, two or several 

 rudimentary leaves (cotyledons) and a terminal bud (plumule). 



Ovules, and seeds, borne on the face of a scale : stigma none. 



Class I. GYMNOSPERMAE. 

 Ovules, and seeds, borne In a closed cavity : stigma present. Class II. AXGIOSPERMAE. 



CLASS I. GYMNOSPERMAE. CONE PLANTS. 



Carpel or pistil represented by a scale upon the face of which 

 the ovules are borne, and on which the naked seeds mature. 



Plants growing by a terminal bud only : leaves circinate ; blades pinnate. 



Order 1. CTCADALES. 

 Plants growing by a terminal and lateral buds : leaves not 



circinate ; blades not pinnate. Order 2. PINALES. 



Order CYCADALES. 



Palm-like or fern-like plants. Leaves in a crown: blades pinnate. 

 Flowers in cones of approximate scales or on slightly modified leaves. 

 Staminate cones with scales bearing several pollen-sacs. Ovulate cones 

 with two or more ovules on each scale. Seed drupe-like or nut-like. 



FAMILY 1. CYCADACEAE. SAGO-PALM FAMILY. 



Dioecious plants with subterranean or erect stems. Leaves spreading: 

 leaflets with 1 or several ribs or veins. Staminate cones deciduous. Ovu- 

 late leaves or cones persistent. Seeds exposed on the margins of the ovulate 

 leaf or enclosed in a cone. 



1. ZAMIA L. Plants with subterranean or erect stems. Leaflets separated, 

 manifestly jointed to the rachis, several-many-veined. Scales of the ovulate 

 aments flat, depressed or swollen at the apex. Ovules and seeds sessile, in- 

 cluded. 



1. Z. floridana DC. Leaves 4-9.5 dm. long: leaflets 28-40, the blades linear, 

 9-14 cm. long, 3-7 mm. wide: mature ovulate cones oblong, densely pubescent 

 with dark brown persistent hairs; the seed-bearing scales thick. Pinelands. 

 F. K. COONTIE. COMFORT-ROOT. COMPTIE. FLORIDA-ARROWROOT. 



Order PINALES. 



Shrubs or trees. Leaves alternate, sometimes clustered or in sheathed 

 bundles : blades scale-like, narrow, or needle-like, or rarely dilated. Flowers 

 mainly monoecious, in cones of spirally imbricate scales, or in Taxaceae the
