372 LXXXV. ASCLEPIADEE (BROWN). [ Schizoglossum. 
The material of this species consists of a few inches of the apical part 
of the plant, which probably attains a height of 1-2 or more ft., with larger 
leaves than those described. I originally placed it in the genus Margaretta on 
account of the position of the pollen-carriers and very similar structure of the 
corona, but its relationship to S. eximium, N. E. Br., and S, simulans, N. E. 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 inflexed as 
in Margaretta, but on re-examination I 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. Jahrb. xxx. 384. Stem 
erect, 14-3 ft. high, 1-1} 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 1-34 in. long, 
34-91 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 44-7 lin. 
long, pubescent. Sepals 3-34 lin. long, 1} lin. broad, lanceolate, acute. 
Corolla white, pubescent outside; lobes 5-54 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—44 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 ? lin. below 
the apex of the style.

This is very similar to S. distinctum, N. E. Br., and may prove to he identical 
when more material is obtained, but it differs in having the coronal-lobes much less 
he at the apex and much less deeply toothed, and especially in the apex of the 
style. 
21. MARGARETTA, Oliver; Benth. et Hook. f. Gen. Pl. 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
