(SALTWORT FAMILY) A unigeneric family distinguished by nearly linear, opposite, succulentleaves, each with a basal appendage and minute stipules: reduced, anemo-philous, imperfect flowers, with a nearly closed sac initially enclosing thestaminate flower, and with a 4-locular ovary and sessile stigmas in the car-pellate flower, a single. basal-parietal, bitegmic, anatropous ovule in eachlocule; and seeds lacking endosperm. TYPE GENTS: Batis P. Br.1. Batis P. Browne, Civil Nat. Hist. Jamaica, 356. 1756. Strong-scented, sprawling, succulent, nearly glabrous, small shrubs rarelymore than 1 m tall, main stems to 2(-4) cm in diameter at the base, majorbranches arching or prostrate and (B. maritima) rooting at the nodes, branch-lets erect or drooping, initially quadrangular in transverse section, becomingterete; bark light gray, flaking. Large irregularly shaped crystals (sodiumchloride?) in most organs (calcium oxalate crystals also reported), and oftenapparently with clusters of salt crystals being excreted through fissures in theepidermis. Wood with the vessel elements mostly solitary or in radial mul-tiples, the perforation plates simple, sometimes bearing thin-walled tyloses:xylem parenchyma vasicentric and banded apotracheal with storied cells: rays `Prepared for the Generic Flora of the Southeastern United States, a project of the ArnoldArboretum currently made possible through the support of the National Science Founda-tion, under Grant DEB-81-11520 (Carroll E. Wood. Jr., and Norton G. Miller, principalinvestigators). This treatment, the 90th in the series, follows the format established in thefirst paper (Jour. Arnold Arb. 39: 296-346. 1958) and continued to the present. The areacovered by the Generic Flora includes North and South Carolina, Georgia. Florida. Ten-nessee, Alabama, Mississippi, Arkansas, and Louisiana. The descriptions are based pri-marily on the plants of this area, with information about extraregional members of a familyor genus in brackets [ ]. References that I have not verified are marked with an asterisk. I thank Carroll Wood and Norton Miller for help with many aspects of the present paper,especially their careful review of the manuscript. For her translations of the French lit-erature and her worthwhile comments on the manuscript. I gratefully acknowledge theassistance of my wife, Donna Rogers. Sydney B. DeVore drew the illustrations, usingcollections made by G. R. Cooley, V. L. Corey, K. A. Wilson, and C. F. Wood. Dr.Wood prepared the dissections for the illustrations.C President and Fellows of Harvard College, 1982.Journal of the Arnold Arboretum 63: 375-386. October, 1982.
