372 Lxxxv. ASCLEPiADE^ (browx). [Schizoglossum. 



The material of this species consists of a few inches of the apical part 

 of the plant, whicli probably attains a height of 1-2 or more ft., with larger 

 leaves tlian those described. I originally placed it in the genus Margaretta on 

 account of tlie position of the pollen-carriers and very similar structure of the 

 corona, but its rehitionship to S. exiinium, N. E. Br., and S. simula^is, N. K, Br., 

 is so undoubted that I place it in Schizoglossum. The flowers are not very good 

 and when I first described them, I thought the basal auricles were infiexed as 

 in Margaretta, but on re-e.\amination 1 believe them to be spreading, and the supposed 

 single tooth on the face certainly consists of two clinging together. 



33. S. scyphostigma, K. Schum. in Engl. Jahrh. xxx. 384. Stem 

 erect, IJ-o ft. high, 1-1 i lin. thick at the base, simple, puberulous, 

 especially below the nodes, at length glabrous. Leaves petiolate ; petiole 

 about 2 lin. long, channelled above, pubescent; blade 1~3| in. long, 

 3-i._9i lin. broad, oblong-lanceolate, acute, rounded at the base, sub- 

 adpressed pubescent on both sides, scabrous on the margins, concolorous. 

 Umbel terminal, " increased by a solitary lateral umbel," pedunculate, 

 8-12-flowered ; peduncle 7-9 lin. long, pubescent; pedicels 4J-7 lin. 

 long, pubescent. Sepals 3-oJ lin. long, \\ lin. broad, lanceolate, acute. 

 Corolla white, pubescent outside ; lobes 5-5-i- lin. long, 3 lin. broad, 

 campanulately-spreading, elliptic-oblong, obtuse and minutely notched 

 at the apex. Coronal-lobes arising at the base of the staminal-column 

 and about twice as long, somewhat spreading, 4-4^^ lin. long, dilated 

 into an obtuse triangular auricle on each side at the base and there 2 

 lin. broad, with a pair of contiguous deltoid or subquadrate teeth on the 

 face, linear and about 1 lin. broad above, obtuse and entire or slightly 

 2-3-denticulate at the apex, apparently white. Staminal-column 2 lin. 

 long, not widened at their base; anthers oblong, their appendages 

 1 lin. long, lanceolate, acute, erect, applied to the sides of the apical 

 part of the style, which is dilated into a pentagonal crater-like apex, 

 with a channel at each angle ; pollen-carriers seated about j lin. below 

 the apex of the style.

This is very similar to S. distinctum, X. E. Br., and may prove to be identical 

 when more material is obtained, but it differs in having the coronal-lobes much less 

 dilated, at the apex and much less deeply toothed, and especially in the apex of the 

 style. 



21. MARGARETTA, Oliver; Benth. et Hook, f . Gen. PI. ii. 759. 



Calyx 5-partite. Corolla very deeply 5-lobed, campanulate; lobes 

 revolute or spreading at the apex, overlapping to the left in bud. 

 Corona of 5 lobes arising from the staminal-column ; basal part claw- 

 like, more or less complicate, with the sides produced into teeth and 

 with or without a tooth in the channel between them ; upper part 

 expanded into a flat petaloid blade usually larger than the petals, 

 variable in shape. Anthers terminated by an erect membranous 

 appendage, adpressed to the sides of the terminal part of the style. 

 Pollen-masses waxy, pendulous, solitary in each anther-cell, attached to
