PARADISE KEY — SAFFORD. 389 



by Dr. H. J. Webber, It was he who first described and figured 

 these remarkable spermatozoids, which exceed in size those of all 

 other living organisms.^ 



The ovules of Zamia floridana develop into beautiful orange-red 

 fleshy fruits arranged about a central axis, like large grains of corn 

 around a cob. These are at first covered by the peltate, triangular 

 scales which bore them, but they fall off when fully ripe and form 

 conspicuous bright-colored heaps in the pine lands where they groAV. 

 A second species of Zamia occurs in the shady woods of Paradise 

 Key, but only male plants have thus far been found there. It has 

 been referred by Small to Zamia integrifolia^ a species in moist 

 woods of middle Florida, particularly near the east coast. This 

 species may be distinguished from Z. foridana by its leaflets, which 

 are somewhat broader, and have 20-28 parallel veins, about twice as 

 many as those of the latter. Both its leaves and its cones bear a 

 close resemblance to those of the West Indian Zamia inedia with 

 which it may possibly prove to be identical ; while Zamia floridana 

 more closely resembles Zamia angustifolia of the Bahamas. 



Among other characteristic plants of the pinelands are the silver 

 palm, the large-seeded Sabal efonia, sometimes called the goose- 

 neck palmetto, and the tall cabbage palm, already mentioned ; among 

 the orchids, the tall, purple-flowered Bletia purpurea and the grass 

 pink, Limjodoi'um pinetoram; the pineland blueberry, Vaccinium 

 myrsinites; the dwarf, white-flowered papaw, Asimina reticulata, the 

 thorn twig, Bumelia reclinata (pi. 33) and the prickly, hollj^-leaved 

 Rhacoma ilicifolia. Among the climbing plants, or twiners, are the 

 beautiful, red-flowered morning-glory, ExogoniuTYi microdactylum., 

 with flower buds resembling fuchsias ; the conspicuous Echites erhifes, 

 belonging to the Apocynaceee, with salver-shaped flowers resembling 

 enormous white jasmines, and a pair of long, slender seed pods in- 

 closing silky seeds; two species of smilax, S. hona-nox, and S. 

 Jiavanensis ,' and occasional moonflowers, Calonyction aculeaturth, 

 climbing to the tops of trees. Among the ferns are the bracken, 

 Pteridium caudatuin; Pteris longifolia; Aiiemia andiantifolia, shown 

 on plate 24 ; and in the old leaf axils of the cabbage palm Phlehodium 

 aureum, on plate 23. In addition to these may be mentioned two 

 plants which are confined to the southern Florida pinelands and do 

 not occur elsewhere — Chainaesyce pinetorum, a low, spreading, hairy, 

 small-leaved plant belonging to the Euphorbiacese ; and the dwarf 

 Florida privet, Forestiera pinetorum, belonging to the olive family, 

 shown on plate 34.
