374 LXXXV. ASCLEPIADEH (BROWN). Margaretta. | 
Mozamb. Dist. German East Africa: Urundi, Scott-Elliot, 8370! 
The flowers are stated on Wilson’s label to be “ dull yellow with a brown spot at 
the base of each petal.’ This doubtless refers to the petal-like coronal-lobes, the 
true petals apparently being rosy-purple. According to Colonel Grant both the 
petals and coronal-lobes are pink.

12-18 in. high, mostly simple, pubescent. Leaves very spreading or 
somewhat reflexed ; petiole 4—2 lin. long; blade 2-5 in. long, 2-11 lin. 
broad, linear to lanceolate, acuminate, more or less pubescent on both 
sides. Umbels about 3-4 in a corymb at the top of the stem, and 
occasionally one from the node below, 7—16-flowered; the upper 
peduncle 4-1 in. long, the lower 14-3 in. or more long, tomentose- 
pubescent, as are likewise the 3-8 lin. long pedicels, and the 1-1} lin. 
long lanceolate acuminate sepals. Corolla-lobes 2—24 lin. long, $ lin. 
broad, lanceolate and acute or oblong and obtuse in different flowers 
in the same umbel, sparsely pubescent on the back, erect, with spread- 
ing or recurved tips, but not revolute. Coronal-lobes arising from the 
base of the staminal-column, suberect, petaloid, 2-24 lin. long, $ lin. broad; 
basal part narrowly complicate, with the inflexed margins produced 
into narrow acuminate teeth 3 lin. long, with a similar tooth on the face of 
the lobe between them ; upper part expanded into a flat narrowly oblong 
blade, entire, bifid or irregularly toothed or lobed at the apex. Anther- 
appendages ovate, lanceolate or oblong, acute, erect. Style capitate, 
subhemispherical or shortly subconical at the apex, obtuse. Follicles often 
solitary, 23-3 in. long, 3-31 lin. thick, lanceolate, acuminate into a beak, 
tapering into a stipe at the base, finely and sparsely pubescent. Seeds 
2 lin. long, 1} lin. broad, ovate, flattened, with thickened margins, scro-

This species varies considerably in the size of its flowers and in the amount of 
toothing at the apex of the coronal-lobes. In the dried state the latter often appear 
to be flat to the base, with 3 teeth on their inner face, but I believe that when alive 
the claw part is complicate as described.
