108 TETRAXDRIA. DIGTNIA. 



giJla, is clotbf d with a very short stellate pubescence. 

 The fiuil of the Fot/ierjilla, as was long ago sagacioubly 

 remarked b) the celebrated \. L. Jussieu, is almost ex- 

 actly similar to that of the Hammnelis^hm in ihe flowers 

 there exists .-^ s. range disparity, by the hitervenlionofthe 

 Pachysarulra, however, which appears more properly re* 

 ferable to the ,ime7itacece, than the EvpJiorbiacecs, and at 

 the same time allied holh to Hamamelis and FothergiUa^ 

 we have something- like a connected sei-ies. In these 3 

 genera, the anthers arid filaments are united, t!ie anthers 

 also become papyraceous, and are for a considerable 

 leng-th of time peisistent, not deciduous as in the Berber 

 rides, l-'iom the Jlmentaccce, tliey differ in possessing? a 

 per sperm, and the HamameUs is excluded from the loth 

 class oi Jussieu by the exisience of petals, but tliis excep- 

 ti(jn IS scarcely universal, as the order in question in- 

 cludes Coi)ipto7na, described as having' 6 petals, at all 

 events, an interior and dissimilar calix. Wherever these 

 3 conti;;uous g-enera may be placed, either as a distinct 

 order, (Fo thergi LLE>t) or as a neiij' bouring- section, 

 tliey cannot but be considered as chsely allied to tlie 

 .imcntacex, notwithstandiui^ the singular construction of 

 the anthers in the genus Hamamelis, wiiich is indeed the 

 'ilt' S' le character by which it is in any manner allied to the 

 Jierberide^., tl.e carreous perisperm being equally com- 

 mon to the E phovbidcea. There is some reason to sus- 

 pect thai tiiegcm s IhnnumeUsis pol}|iamous, independent 

 of the mistake of L.misens in confound. ngtiiis genus with 

 Fothergilla. 'I he variety, foi- insiance, whicli I have de- 

 signated, y. * parxHfolia, although flowering freeh every 

 year, lias never produced seed since transplanted into a 

 garden out ot coniact w ith o hei- individuals. Tliis sub- 

 ject, however, requin.s more gene; aland accurate exami- 

 nation. The three i^enera proposed are thus far exclu- 

 sively confined to Noi th America. 



161. SANGLISORBA. L, (Great Burnet.) 



Calix 2-le.aved, inferior, resembling bractes. 

 Corolla 4-rJt ft, superior. Capsule^ between the 

 calix and corolla, 2 seeded. 



Herbaceous; leaves unequally pinnate, stipules growing 

 to the base of the petiole flowers capitate terminal. 



Species. 1. 6'. ccmcidensis. 2. media. Probably a mere 

 variety of No. 1. Of this genus there are but 2 other spe- 

 cies, 1 in Europe and the other in Algiers (Africa.)
