SHRUBS OF FLORIDA. 



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 wanting. I. GYMNOSPERMAE. 

 Ovules, and seeds, borne in a closed cavity (ovary) : stigma 



present. II. ANGIOSPERMAE. 



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 seeds mature. 



Plant growing by a terminal bud : leaves circinate : blades pinnate. 1. CYCADALES/ 

 Plant growing by terminal and lateral buds : leaves not circinate ; 



blades not pinnate. 2. FINALES. 



Order CYCADALES. 



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

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

 Staminate cones with scales bearing 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 one or several ribs or veins. Staminate cones deciduous. 

 Ovulate leaves or cones persistent. Seeds exposed on the edges of the 

 ovulate leaf or enclosed in a cone. 



1. ZAMIA L. Fern-like plants, growing in sandy soil. Leaflets jointed 

 at the rachis, with parallel veins. Cones stalked, the scales peltate, spiral, the 

 mature pistillate ones erect. COONTIE. COMFORT-ROOT. COMPTIE. 



Leaflets 10-16-veined : fruiting cones 12-16.5 cm. long, markedly umbonate. 



1. Z. floridana 



Leaflets 20-28-veined : fruiting cones 6.5-10.5 cm. long, scarcely um- 

 bonate. 2. Z. pumila. 



1. Z. floridana DC. Leaves 4-9 dm. long; leaflets 28-40, the blades linear, 

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

 dark-brown persistent hairs, the seed-bearing scales thick. FLORIDA-ARROWROOT. 



Dry pinelands, the E. Keys and F. Keys, and "flat woods," s. pen. Fla. (Endemic.) 



2. Z. pumila L. Leaves shorter than those of Z. floridana; leaflets 32-44, the 

 blades linear-oblanceolate to linear-oblong, 7-11 cm. long, 8-16 mm. wide:
