flowers very large glaucous, segments of corolla 

 patent ovate obtuse ; deemed a Calotropis by 

 Collins, but a real Annntherix and by no means 

 a Stylandra N. or Podostima E. To the same 

 Genus appears to he\oi\g A sclepias connixens of 

 Baldvv. Elliot &.c which is very akin to this in 

 leaves and flowers, but has stem terete and 

 leaves opposite narrower, white ringed warts on 

 the stem, I'll call it Anantherix verrucosa: 

 my specimens are from Alabama. A. viridis 

 N. differs by leaves narrower thick pubescent, 

 umbels lateral subsessile Slc, 



985. OLIGORON Raf. Acerates Elliot. 

 See my article Acerotis in first part. I have 

 since divided them. My name is found in Di- 

 oskorides for an Apocynum. Acerates w^as bad 

 derived from Acer and Aceras. This G. will 

 be easily known by the sessile scattered leaves, 

 the erect umbels and 5 small shining tips upon 

 the staminal apparatus, auricles adpressed with- 

 out appendages. 



886. Oligoron longifolium Raf. Asclepias 

 do Mx. Ascl. floridana Lam. Acerates longif. E. 

 —Pubescent, leaves linear lanceolate elongate 

 trinerve, umbels peduncled multiflore, auricles 

 shorter than stamens — Carolina to Florida and 

 Arkanzas, leaves 2 to 6 inches long, flow^ers tri- 

 color, centre yellow, corolla white, tip purple. 

 The structure of the central apparatus is very 

 peculiar, the little lucid tips almost concealed 

 in the wings. — Var. Hirsutum, several umbels 

 with great many flowers 50 to 60, pedicels long 

 hirsute. 



887. Oligorun tenuifolium Raf. smooth, 

 leaves narrow linear acute uninerve, margin 

 revolute, rugose ; umbels sessile multiflore, au- 

 ricles as long^ as stamens. — A very distinct sp.
