Bull Thatch Palm
| Sabal (SAH-bahl) |
Habitat and DistributionSabal maritima is endemic to Cuba, and Jamaica.
Sabal maritima, is a fan palm with a solitary, stout trunk, which grows up to 15 metres (49 ft.) tall, and 25–40 centimetres (10–16 in.) in diameter. Crown holds about 25 costapalmate leaves, with recurving leaf tips, each with 70–110 leaflets. The inflorescences, which are branched, and as long as the leaves, they bear pear-shaped to globose, black fruit. The fruit are 0.8–1.4 centimetres (0.3–0.6 in.) in diameter. Editing by edric.
Full sun, moderate water, well drained position. Hardiness USDA zones, 9A-11.
Comments and Curiosities
This is a tillering palm, it exhibits saxophone style root growth (it has a heel), keep top third of heel above soil elevation!
Andrew Henderson and colleagues noted that Sabal maritima, S. causiarum and S. domingensis form a species complex that may constitute a single species. The species are readily distinguished on the basis of fruit size and shape. Sabal domingensis has pyriform fruit, 11.5-14.1 (12.7 ± 0.7) mm in diameter and 11.0-14.4 (13.1 ± 1.0) mm high. Sabal causiarum has spherical or occasionally oblate-pyriform fruit, 7.1-10.8 (9.8 ± 0.5) mm in diameter and 7.5-10.4 (9.4 ± 0.7). Sabal maritima has oblate-pyriform to oblate-spherical fruit, 8.5-14.2 mm in diameter, 8.4 - 1 2.6 mm high. A similar size difference is found in the seeds: 8.0-10.4 mm in diameter, 5.1-7.1 mm high for S. domingensis versus 5.9-7.8 mm in diameter, 4.3-5.7 mm high for S. causiarum and 6.5-9.7mm in diameter, 4.5-6.2mm high, with a smooth (rarely some-what beaked) funicular remnant.
Another difference is that the petioles of S. maritima are densely covered with light-colored scales and appearing whitish or tan with a small, triangular to square-shape ligule at petiole base. S. maritima also has a rachillae with very crowded flowers, whereas the flowers are not crowded much in S. causiarum. Donald Hodel also mentions that Sabal causiarum can be distinguished from S. domingensis and S. causiarum by the presence of conspicuous, large, tan, flap-like ligules at petiole base. This characteristic is not mentioned in Scott Zona’s 1990 monograph of Sabal.
Diagnostic features: "The two species are similar, but S. maritima has the young petioles densely covered with light brown scales (which tend to fall off as the leaf ages, so look for this on the youngest leaves in the crown). An even easier distinguishing feature is the density of flowers on the rachillae. In S. martima, the flowers are really crowded on the rachillae. They even touch one another. Not so in S. causiarum, where the flowers are not crowded at all." (Dr. Scott Zona)
