\la. Asclepias Ksessueri, X. E. Br. in Journ. Bot. 1903, 362. 

 Stems erect, branching, white-woolly on the young parts, becoming 

 glabrous below. Leaves ascending-spreading; petiole ^-\ in. long, 

 woolly when young; blade 3|-6| in. long, \-h in. broad, linear-lanceo- 

 late, tapering to a very acute point, more or less acute at the base, with 

 flat or narrowly revolute margins, glabrous on both sides or with a very 

 minute scattered pubescence above and thinly woolly on the midrib 

 beneath. Umbels several, racemose, 4-G-flowered, ascending. Peduncles 

 and pedicels equal, |-li in. long, woolly. Sepals 2-|-3^ lin. long, 1 lin. 

 broad at the base, thence tapering to a very acute point, woolly, 

 reflexed. Corolla lobed almost to the base, reflexed, apparently whitish 

 or yellowish ; lobes 4^-5 lin. long, 2i-2J lin. broad, ovate, obtusely 

 pointed, shortly ciliate on one margin, otherwise quite glabrous. 

 Coronal-lobes arising |-| lin. up the staminal-column and reaching to 

 the same level, l|-2 lin. long and about as broad, cuneately suborbi- 

 cular in side view, much compressed, divided for only ^ of the distance 

 from the inner to the dorsal margin, with a falcate denticulate tooth 

 from the side, apical angles recurving within a groove along the top of 

 the lobe about J lin. deep, which has a keel or crest along the bottom 

 of it ; each side of the lobe (in the dried state) has a ridge correspond- 

 ing to the depth to which it is divided, and is narrowly winged at the 

 base and inner margins. Staminal-column '2\-2^ lin. long; anther- 

 appendages transverse, \ lin. long, | lin. broad, very obtusely rounded.
