cordate, end obtuse or retuse m tier on ate, mar- 

 gin ciliolate, nerves reticulate, beneath almost

 pedicels very short, auricles very large obovate 

 truncate longer than stamens and appendages 

 Florida, sent me by Torrey as the A. obova- 

 ta of Elliot, which is tomentose with obovate 

 leaves and probably an Otanema perhaps even 

 a var. of O. latifolia. This sp. is a real Ascle- 

 pias, with curved subulate appendages in the 

 auricles, leaves 2 or 3 inches long, one broad, 

 flowers large white. 



893. ASCLEPIAS ALBIFLORA Raf. Ascl.nivea/ 

 and A. incarnata of some Amer. Bot. stem pu- 

 bescent, leaves ample thin nearly smooth sub- 

 sessile, elliptical lanceolate, base obliqual, end 

 acuminate, nerves pubescent; umbels terminal 

 corymbose, auricles equal to stamens and ap- 

 pendages fine sp. from the Unaka or Iron 

 Mts. of i\. Carolina, seen alive in gardens, where 

 deemed a white var. of A. incarnata, yet much 

 nearer A. nivea a sp. known to few : with 

 broader shorter leaves, lateral flowers with 

 green petals and white centre says Linnetis. 

 This has flowers perfectly white small but hand* 

 some, stem bipedal, leaves very large 6 inches 

 long, two broad, 



I could add or rectify many other sp. of As- 

 clepias, and give again my A. maritima quite 

 different from the smooth A. incarnata ; and 

 ray A. vanilla the deviation of A. quadrifolia 

 with opposite leaves, but I must leave this for a 

 monograph ; I have nearly all the numerous N. 

 Amer. sp. A.cinerea, puLchra,aifnena^ pauper 

 cula, amplexicauliS) obtusifolia, curassavica, 

 Jaurifolia, peroplicifolia, variegata, phytola- 

 coides <c. I deem this G. must be divided
