228. MYCTANTHES (mixed flowers) Raf. 

 anomalous or peloric Genus occasionally form- 

 ed by some Asters and Solidagos — Difference, 

 flowers often concrete or coalescent, with ligu- 

 les and floscules intermixt, perianthe imbri- 

 cate unequal foliaceous. I have noticed seve- 

 ral types. Is it a diseased state ? but the 

 plants were healthy. 



225. Myctanthes punicea R. like Aster 

 puniceus, but stem simple, 2-3flore, leaves lan- 

 ceolate — observed near Philadelphia, flowers 

 terminal purplish. 



230. Myctanthes latifolia R. stem sim- 

 ple uniflore, leaves sessile elliptic acuminate 

 subserrate, flower terminal sessile purplish^ — 

 collected in the Alleghany mts. bipedal. 



231. MvcTANTHEs AXILLARIS R. similar to 

 Solidago nemorosa, but flowers axillary and 

 solitary, yellow — mts. Alleghany, pedal. 



233." ALISETA (Plantain) Raf. Radiate 

 Genus near to Arnica — Perianthe in double 

 series, each of ten spreading folioles. Phoran- 

 the flat alveolate, chaflfs carinate long acute. 

 Floscules tubulose 5fid sterile. Ligules or rays 

 about 20 fertile tridentate narrow. Seeds li- 

 near, pappus simple deciduons. Habit of Ar- 

 nica^ scapose, uniflore — But very different 

 Genus by calix, chaffs, sterile florets &c. It is 

 nearer to the next Genus Peritris in some re- 

 spects. Single type. 



233. Aliseta PLANTAGiNEA R. radical leaves 

 lanceolate or cuneate entire hirsute acute, 

 scape terete smooth, with a single subulate 

 scale, uniflore. folioles of perianthe ovate lan- 

 ceolate smooth — Sent me from Florida, prob-
