twenty new species of plants, among which 

 he TaQTit\ons)Rmmnculus mutabilis, Trillium 

 revolutum, Monarda pratensis, Eupatorium 

 serotinum, Silene fistulosa, Cactus mesocan- 

 tha, Hepatica parviflora, etc., none of which 

 he describes. The name Eupatorium ser- 

 otinum was used by Michaux in 1803. 

 Other proposed names which have not 

 found their way into synonymy are Genti- 

 ana glauea, Pedieulars [sic] villosa, Martynia 

 rotundifolia, Veronica connata, Zigadenus an- 

 gulosus. It is pointed out that Gentiana 

 amarelloides Michaux is not the same as G. 

 quinquefiora Linne, with which Pursh had 

 confused it. Among some plants received 

 'from some ladies,' three new ones are 

 mentioned: Lysimachia (Trydinia) glauea, 

 Gentiana azurea, and Trillium reflexum, th,e 

 latter ' differing from T. sessile, by its petio- 

 lated leaves, reflexed calyx and pale purple 

 petals.' Some new names for plants from 

 Missouri are Gnaphaliuvi nemocladum, Me- 

 lothria alba, Asplenium glaucum, A. falca- 

 turn, but which are also not described. 

 Melothria nigra Raf. ' is common near Nat- 

 chez.' And the following are recorded 

 from Kentucky presumably for the first 

 time: Pancratium liriosme Raf., Iris brevi- 

 caulus Raf., Ptelea trifoliata, Arenaria divari- 

 cata, Lohadium trifoliatum Raf. {Rhus aroma- 

 ticum Ait.), Triosteum minor, Nelumbium pen- 

 tapetalum, Agave virginiea. Iris eristata, etc. 

 In a postscript Rafinesque states that 

 a new genus, Geminaria, must be formed 

 for Phyllanihus Carolinianus Walter and 

 Michaux (called P. obovatus by Wildenow, 

 Persoon, Pursh, and JSTuttall). Signed C.

On the several species of the genus Clin- 

 tonia, addressed to Dr. Samuel L. Mitch- 

 ell, in a letter dated September 26, 1819 

 [pp. 42, 43. This is a review of the 

 genus. The author reverses his former 

 opinion that Dracena borealis Alton, and 

 Convallaria umbellulata Michaux are synony- 

 mous. Four species are recognized as fol- 



lows : "1. Sp. Clintonia nutans. Leaves 

 with ciliate margin, keel smooth: umbel 

 sub- corymbose, pedicels smooth naked nod- 

 ding unequal, perigone campauulate, sepals 

 oblong sessile subacute. — Dracena borealis 

 Ait. Wild. Pers. etc., flowers lerge [sic] 

 yellowish inodorous. New York to Canada 

 on mountains. Var. 1. Prolifera. Corymb 

 proliferous. — Var. 2. Fascicularis, flowers in 

 separate fascicles. 3. Obovata. Leaves 

 nearly obovate. 4. Dasistema, scape pubes- 

 cent. 5. Maerostema. Scape longer than 

 the leaves. Var. 6. Uniflora, etc." 



"2. Sp. Clintonia podanisia. Leaves with 

 ciliate margin, keel smooth ; scape pubes- 

 cent longer than the leaves ; umbel erect, 

 pedicels unequal pubescent naked, the 

 longest erect, the others incurved : perigone 

 semi-campanulate, sepals oblong, sessile, 

 acute. — Discovered in July, 1819, on the 

 Laurel ridge in Pennsylvania. Flowers 

 pretty large whitish, inodorous. Var. 1. 

 Biflora, with only 2 flowers, the shortest 

 v^ith incurved pedicel, leaves narrow, semi- 

 cuneate. Var. 2. Glabrata. Scape smooth. 

 Var. 3. Faseicidaris. 2 umbels, the second 

 lateral, each vrith 3 or 4 flowers. Var. 4. 

 Phyllostema. One small lanceolate and acute 

 leaf on the scape. " 



"3. S. Clintonia parviflora. Leaves with 

 pilose margin and keel, scape pubescent, 

 equal to the leaves ; umbel creet [sic] * 5-8 

 flore, pedicels equal, naked pubescent erect, 

 perigone semi-rotate, sepals semi-onguicu- 

 lated [sic] , claws erect, disk oboval obtuse. 

 Discovered in July, 1819, on the top of the 

 Allegheny Mountains in Maryland. Flow- 

 ers small, perfectly white, nearly inodorous. 

 Var. 1. Plicata. Leaves folded falcated. 

 Var. 2. Abortiva. Some abortive sessile 

 flowers in the umbel." 



" 4. S2). Cintonia [sic] odorata. Leaves 

 oblong-oval, with ciliate margin and keel ; 

 scape pubescent, umbel erect, pedicels brac- 

 teated. — Convallaria umbellulata Mx. Pers., 



* Erect ?
