Teysmannia
(so called in honour of J. E. Teysmann, a Dutch gardener, who published a "Catalogus Plantarum," in 1838). ORD. Palmae. A monotypic genus. The species is a dwarf, unarmed, stove Palm, closely allied to Corypha, from which it differs mainly in habit. The natives of Sumatra use the leaves of this Palm for thatching their houses, a purpose for which, from their large size and entire form, they are admirably adapted. For culture, see Corypha. T. altifrons (tall-leaved). fl., spathes papery-coriaceous, sheathing the fuscous-tomentose peduncle and the spadix branches; spadix rather short, with deflexed branches. fr. as large as an apple, globose or depressed-globose, one-celled, one-seeded. l. erect, elongated-rhomboid, obtuse, acute at base, 6ft. to 7ft. long, 1 1/2ft. wide, induplicately plicate, laciniated on the margins, the segments obtusely bifid; petioles carinate at back, obsoletely concave in front, the angles rounded, uncinate-prickly. Caudex subterraneous. Sumatra.
