SI 2 ICOSANDEIA. POLYGYRIA. 



face scabrous with minute aculel, the under smootii, 

 glaucous or villous; younger branches more or Jess quad- 

 rang-ular, flowers terminal, solitary, petaloid segments 

 disposed nearly in 2 series, bi'ownish, the interior ones of- 

 ten stammlferous, and the innermost filaments sometimes 

 without anthers. ^^ 



Species. l.Cforidus. Obs. jPlveb rariable, broad 

 oval, or oval-oblong, acute; villous on the under side; the 

 wood and particularly the root strongly campiiorated, so 

 as to be calculated probably to produce that drug as abun- 

 dantly as Lanriis cwnpliova. Flowers at first dark brown, 

 becoming paler, in drying parting entirely with this color 

 and becoming olive green, agree:ibly scented, almost like 

 ripe apples, similar to all the other Xorth American spe- 

 cies. Anihei's and filaments minutely pubescent, the for- 

 mer glanduiif'erous utthe summit, interior filaments with- 

 out anthers. Seeds brown, nearly as larije as horsebeans, 

 naked, smooth and shining, about 16 in each utricuhis, of 

 ai'ourulish oblong form, marked with a lons^itudinal suture 

 and a central hilum; shell hard and cartilaginous; peris- 

 perm none, or a small central portion gelatinizing when 

 moistened; radicle descendant; cotyledones convolute, 

 white and larp,e, of an oleaginous bitter taste. Capsule 

 turbinate, as large as a small pear, marked with the vesti- 

 ges of the calycine lacinije, at lengtii becoming perfectly 

 dry with the seeds loose, but never opening. 



Z. Collins Esq. informs me that by cutting off the termi- 

 nal leaf-buds, after the usual season, a succession of flow- 

 ers may be obtained throughout the summer, every leaf- 

 bud so extracted being constantly succeeded by 2 flow- 

 ers. For 4 years Z. Collins has been a witness to the 

 success of this experiment, showing in this genus the ve- 

 ry intimate union wiucli subsists betwixt ihe leaves and 

 singularly confluent flowers. From the rarity of fruit 

 in the Calycanthi, even in their native mountains, we may 

 almost assert, that this genus, notwlvhstanding the consi- 

 m'.larity of its flowers, is m fact polygamous. 



2. glaucus. On the declivities of bushy hills and the 

 margins of small streams near Lincolnton, (N. Carol.) 

 8tc. /3. * oblongifolius, leaves oblong-lanceolate, acu- 

 minate, under side smooth and glaucous. Hab. In the 

 mountains of North Carolina, a permanent variety, hav- 

 ing elongated leaves. 3. Ixvigatus. Leaves scabrous a* 

 bove, green and smooth beneath. 



A ISorth American genus with the exception of C. prx- 

 tax of Japan.
