Sabal

Plants dwarf, moderate, or tall, usually robust. Stems solitary, aerial or subterranean, covered with leaf bases or clean, obscurely [strongly] ringed, becoming striate or smooth with age. Leaves few to many; sheath fibers soft; petiole split at base, completely unarmed; adaxial hastula well -developed, obtuse to acuminate-triangular; costa present; blade weakly to strongly costapalmate; plication induplicate; segments lanceolate, basally connate to connate for 2 1/2 length [or in groups of 2 or 3 segments connate for nearly entire length], often bearing thread-like fibers between segments; apices acute or 2-cleft, stiff or lax. Inflorescences axillary within crown of leaves, paniculate, erect or arching beyond leaves [shorter than leaves], with 2 or 3[--4] orders of branching; peduncular bracts 2--5, tightly clasping, inconspicuous; rachillae glabrous. Flowers bisexual, borne singly along rachillae, sessile, creamy white, fragrant; perianth 2-seriate; calyx cupulate; 3-lobed; petals 3, imbricate, elliptic, obovate or spatulate, alternate with outer whorl of stamens [basally connate], basally adnate to filaments; stamens 6 in 2 whorls; filaments narrowly triangular, basally connate; anthers dorsifixed, versatile; pistils 1, 1-carpellate, glabrous; nectaries 3, septal; ovules 3, but usually only one develops into seed; stigma minutely 3-lobed, papillose. Fruits drupes, berrylike, spheroid [oblate or pyriform ] or lobed when more than 1 seed develops; exocarp black; mesocarp blackish, dry to fleshy; endocarp brown, membranaceous. Seeds 1--3, oblate, glossy; endosperm bony, homogeneous; embryo nearly apical, lateral or nearly lateral; eophyll undivided, linear-lanceolate. nx = 18.

Sabal flowers are bisexual and are pollinated mostly by native bees, especially of the families Halictidae and Megachilidae (S. Zona 1987, 1990), European honeybee, and wasps (Vespidae; P. F. Ramp 1989). Fruits are eagerly sought by both mammals (bears, deer, raccoons) and birds (S. Zona and A. Henderson 1989). Sabal minor, perhaps more than other species, is also dispersed by water (P. F. Ramp 1989; S. Zona 1990).
