flowers very large glaucous, segments of corolla 

 patent ovate obtuse ; deemed a Calotropis by 

 Collins, but a real Anantherix and by no means 

 a Stylandra N. or Podostima E. To the same 

 Genus appears to belong A sclcpias connitens of 

 Baldw. 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 vcrrucosa : 

 my specimens are from Alabama. A. riridis 

 N. differs by leaves narrower thick pubescent, 

 umbels lateral subsessile &c. 



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 was 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 LONGIFOLITJM Raf. Asclepias 

 do MX. Ascl. floridana Lam. Acerates long if. 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 r 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. OLIGORON TENUIFOLITJM Raf. smooth, 

 leaves narrow linear acute uninerve, margin 

 revelute, rugose ; umbels sessile multiflore, au- 

 ricles as long as stamens. A very distinct sp.
