[SCHL 



corymb, the outer ones much enlarged 

 and barren ; and only appears to differ 

 from that genus in the ovary and fruit 

 having four or five cells instead of two 

 only. 



SCHIZOPHYLLUM. A remarkable ge- 

 nus of gill-bearing Fungi, in which the 

 coriaceous gills are split through their 

 whole length along the central substance 

 or trama, the two divisions turning back 

 and becoming involute. The pileus is 

 white, or slightly tinged with red or amber, 

 and is more or less rough with little bun- 

 dles of short threads, the margin variously 

 lobed, and the surface zoned. " The species 

 are few in number and essentially tropical, 

 S. commune, the most universal of tropi- 

 cal fungi, extending, though rarely, into 

 temperate regions. It is one of the fungi 

 which frequently make their appearance on 

 imported wood in hothouses, and is always 

 in such situations a pleasing object. In a 

 natural situation it is one of our rarest 

 fungi, and has been seen by very few 

 mycologists. [M. J. B.] 



SCHIZOPLETJRA. The name of a genus 

 of shrubs of the family Myrtacecv. The 

 species are natives of Swan River, and are 

 closely allied to Beaufortia, the points of 

 distinction beingthese :— Flowers interim- 

 nal heads ; calyx detached from the ovary ; 

 anthers opening horizontally ; ovary free ; 

 capsule parchment-like, included within 

 the thickened calyx-tube. [M. T. M.] 



SCHKUHRTA. A genus belonging to 

 the Compositce and the subtribe Helenece, 

 and comprising about a dozen species, 

 which are spread over Mexico and South 

 America. All are much-branched slender 

 annual weeds of little beauty, having pin- 

 nate!;." cut or tripartite leaves, and solitary 

 yellow flower-heads arising from the axils 

 of the leaves or the ends of the branchlets. 

 The involucre of about five obtuse scales 

 encloses from four to ten florets, from one 

 to five of which are strap-shaped and pis- 

 til-bearing, the others tubular and perfect. 

 The achenes are three to four-angled, and 

 crowned with a pappus of six or eight 

 broad membranaceous scales, which are 

 either all rounded at the apex, or all 

 bristle-pointed, or the alternate pointed 

 and the others blunt. Achyropappus and 

 Mapkirkia are synonyms of the genus, 

 which bears the name of Ch. Schkuhr, a 

 German botanist. [A.A.B.] 



SCHLAGIXTWETTIA. The Bieracium 

 aUridum, a well-known hawkweed of the 

 Alps of Southern Europe, has been separa- 

 ted under the above name, mainly, as it 

 would appear, from its having a few folia- 

 ceous bracts surrounding the flower-heads. 

 It is a herb about six inches high, all its 

 parts clothed more or less with dark glan- 

 dular hairs; the stems are simple or slightly 

 branched, furnished with lanceolate dis- 

 tantly toothed leaves, and terminating in 

 solitary pale-yellow flower-heads about an 

 inch across. It was named in honour of 

 the brothers Schlagintweit, who travelled 

 in Xorth-western India and Central Asia, 



where one of them met a cruel and un- 

 timely fate. [A. A. B.] 



SCHLECHTEXDALIA. A rather hand- 

 some erect perennial herb of Montevideo, 

 remarkable in the tribe Mutisiece of the 

 Compositce for its peculiar ha"bit. Its un- 

 branched rather robust stems, from six 

 inches to two feet high, are more or less 

 clothed with soft rusty hairs, and furnish- 

 ed (chiefly at the base) with rigid grassy 

 leaves like those of Luzula alba, whence 

 the plants receive the specific name of 

 luzulcefolia. The stems terminate in from 

 one to five stalked flower-heads, each fur- 

 nished with an involucre of numerous 

 straw-coloured narrow slender-pointed 

 scales, enclosing a goodly number of 

 yellow florets : these are all tubular, per- 

 fect, and deeply divided into five equal 

 narrow portions, clothed outside with 

 short silky down. The top-shaped achenes 

 are clothed with soft hairs, and crowned 

 with a pappus of broad slender-pointed 

 unequal pales. It has been named after 

 Dr. F. L. Schlecktendal, an eminent Ger- 

 man botanist. [A. A. B.] # 



SCHLEGELIA. A name given to some 

 plants now referred to Tancecium. [B. S.] 



SCHLEICHERA trijvga, the tropical 

 Asiatic plant upon wiiich this genus of 

 Sapindacece is founded, was formerly com- 

 bined with the closely allied American 

 Melicocca, from which, however, it is dis- 

 I tinguished by its flowers having a five- 

 ; toothed calyx, no petals, from six to ten 

 I stamens inserted between the ovary and 

 the disk, and occupying the centre of the 

 flower, a three-celled ovary terminated by a 

 style, and a three-cleft stigma. It is a large 

 ; tree, and has abruptly pinnate leaves coin- 

 : posed usually of three pairs of leaflets, and 

 j spike-like racemes of small flowers, suc- 

 i ceeded by round one two or rarely three- 

 celled fruits, with a solitary seed covered 

 with a pulpy arillus in each cell. It is 

 ! common in the peninsula of India 

 | (where it is called Koosumbia), in Ceylon, 

 and also in Burmah, where its timber is 

 employed for purposes requiring great 

 strength and solidity. In India and Ceylon 

 the lac-insect (Coccus) frequents this tree ; 

 and considerable quantities of stick-lac, 

 from which part of the shellac and lac-dye 

 of commerce is prepared, are collected 

 from its young branches. An oil also is 

 expressed from the seeds, and used both 

 for burning in lamps, and also as a cure for 

 | the itch. [A. S.] 



j SCHLEIDENIA. Agenus of Boraginacece, 

 consisting of small prostrate Brazilian 

 herbs, with alternate narrow entire leaves, 

 and small axillary white or yellow flowers, 

 solitary or in spikes. The genus is closely 

 allied to Heliotropium, and has the habit 

 of some of its smaller tropical species, 

 and indeed scarcely differs except in its 

 fruit, which is a small drupe enclosing 

 four nuts, instead of separating into two 

 or four distinct dry nuts. There are four 

 species, all of a very weedy aspect.
