lobed, every where verj' smooth and thin, under side ob- 

 soletely veined, petiole longer. White Sassafras.) Hab = 

 In North and South Carolina abundant, from the Cataw- 

 ba mountains to the east bank of the Santec; growing 

 with the common species, which is in North Carolina less 

 abundant. I have not seen it in flower, therefore the 

 •omparison is incomplete, but all the inhabitants distin- 

 guish them perfectly by the names of white and red Sas- 

 safras, this species is also sometimes denominated Smooth 

 Sassafras; the root is much more strongly camphorated 

 than the ordinary sort and nearly white; it is also better 

 calculated to answer as a substitute for Ochra {Hibiscus 

 esculcntns') than E. Sassajras, its buds and young bran- 

 ches being much more mucilaginous. 



The genus Ocotea of Aublet appears to be very nearly 

 related to the present, but the flowere are paniculated; 

 and the filaments of the anthers are described as broad 

 and truncate.f 



Order IL—TRIGYNIA. 



375. ERIOGONUM. Michaux.. 



Calix subcyatliiform, tubiilous at the base, 

 border 6-cleft, segments unequal, externally 

 villous. Corolla none. Seed 1, triquetrous, 

 without margins, covered by the calix. (Flow- 

 ers involucrate. Stipules none.) 



Herbaceous or suffruticose plants, mostly stemiess and 

 cespitose, with alternate leaves, more or less tomentose; 

 flowers involucrate; involucrum cup-shaped or campanu- 

 late, many -flowered (15 to 20;) flowers circularly articu- 

 lated to the peduncles, many of them deciduoui. {E. to- 



I This is the Porostema of Schreber's genera, and apparent- 

 y fictitious, so far as it varys from the account of Aubiet. It 

 is described as having a 6-parted calix; 9 filaments called nec- 

 taries, arranged in 2 series, 3 of them being internal and furnish- 

 ed with glands, each of these filaments is said to produce 4- 

 pores (evidently the 4 polliniferous cells of L. Sassafras, and 

 L. gcdculata) but monstrous to relate, there arises from all 

 these 3^ pores, so many filaments supporting peltate anthers! 

 and instead of a drupe containing 1 seed, as described by the 

 accurate and celebrated Jussieu, we have to learn that it pro= 

 ducfs a capsule with several cells, and jnany seedal
