86,. Azalea fragrans. Foliosiflore, leaves oblong-cuneate, bristly-ciliate,_ base 

 acute, end obtusely mucronate, glaucous beneath; umbels interfoliate, multiflore, 

 bracteate, bracteas scaly, ovate obtuse, concave, tube elongate, viscose pilose, 

 stamina and style twice as long as the corolla. — A beautiful shrub, three to four 

 feet high, growing on the mountains of Maryland and Virginia. Flowers large, 

 white, smelling like Caprifolium and blossoming in June. 



87. Oxalis montana. Stemless, creeping, caudex fibrose, petioles flaccid, foH- 

 oles thin, obcordate, dilatate, almost reniform, smooth, slightly ciliate, scape uni- 

 fiore equal to the leaves, styles and petals longer than the stamina, petals cune- 

 ate, emarginate. — This is the O. acetqseUa of Pursh, but not of Linneus. I found 

 it on the summit of the Catskill mountains in the state of New- York. Petals 

 white, veined with purple, base yellowish, blossoming in June. 



88. Delphidium { Delphinium J flexuosum. Nearly smooth, stem upright, sim- 

 ple, thick and flexuose, leaves on long petioles, palmated, divisions bifid, some- 

 what laciniate, lanceolate acute ; raceme thick ovate, flowers nodding, spur ad- 

 scendent, rather curved, as long as the corolla ; capsules quatemate. — A small 

 but fine species discovered on Turtle creek, near Pittsburgh. It rises only one 

 foot, it blossoms in May, flowers dark violet with a white palate, raceme often 

 with eight flowers. I have modified the name of Delphinium which was nearly 

 identical with Delphinus a genus of animals. 



89. Dentaria parvifolia. Root tuberose vermicular, stem slender, leaves trifoli- 

 tate, the radical ones with folioles petiolate, ovate, acute, serrate, laciniate, those 

 of the caulinar leaves sessile lanceolate, serrate or entire. — A small species, rising 

 only four to six inches. I found it on the beautiful banks of the Loyalhannah 

 creek in western Pennsylvania ; it blossoms in May , flowers of a pale rose colour, 

 stigma capitate, raceme slender, leaves small. 



90' SiUne miniata. Stem viscid, pubescent, striated, leaves oblong, acute, pu- 

 bescent, the radical ones petiolate, ciiiolate and slightly undulate ; flowers ter- 

 minal few, calix viscid, cylindrical-clavate, decangular, petals obtuse, bidentate, 

 capsule globose-clavate, unilocular — A fine perennial species, about a foot high, 

 leaves remote, flowers scarlet, like red lead and dazzling bright ; but fading in 

 drying. I have seen it sometimes with four petal, eight stamina, &c. It may be 

 probably necessary to re-establish the genus Atocion of Adanson, containing the 

 species of Silene with unilocular capsules, in which case this species may be called 

 Atocion miniatum.. 



91. Rumex sylvatica. Root tuberose, cylindrical, fusiform, stem angular, fur- 

 rowed, straight & simple, leaves petiolate, ovate, oblong, nearly entire, flat, acute 

 at both ends ; raceme elongate, naked and articulated, calix with the external se- 

 pals small, oblong, obtuse, internal ones or petals lacerated ovate, one granular, 

 grain spherical, very large. — Discovered in the woods of western Kentucky, blos- 

 soming in August ; stem hardly over one foot high, radical leaves small. 



92. Polygonum punctatum. Stem branched, leaves broad lanceolate, acumi- 

 nate, dotted beneath, petiolate, sheaths nervose mutic ; spikes dense, elongate, 

 bracteas ovate, acuminate, membranaceous, flowers geminate, nearly sessile ; ca- 

 lix unequally quinquefid, divisions obtuse, two larger, five stamina, two styles, 

 seeds obtuse lenticular. — It grows in western Kentucky and blossoms in August ; 

 flowers white, stem two or three feet high. The genus Polygonum, must soon be 

 divided, this then will form a genus or sub-genus, with the other species having 

 an unequal calyx, five stam. two St. and lenticular seed ; it might be called Chulu- 

 sium.. 



93. Polygonum serotinum. Shrubby, stem upright, striated, much branched; 

 branches angular, virgate ; leaves nearly sessile, ovate-oblong, acute, smooth; 

 sheaths split laterally, lacerated, membranaceous ; flowers axillary, fasciculate, 

 pedunculate, polygamous : calyx rhomboidal, unequally quinguefid, five stamina, 

 three sessile stigmas ; seed unequally triangular, conical, smooth, longer than the 

 calix. — A large species, discovered near Lexington in fields ; it forms a small 

 shrub two or three feet high, woody only at the base and blossoming in October. 

 It approximates to P. ramosissimum of Mx, & P. parvifolium- of Nuttall ; but not at 

 all to P. erectum of L. which Pursh has wrongly united with the former. Branches 

 nearly naked, leaves very small, flowers two to five together on peduncles as long 

 as them, green, tip rose coloured. This species will probably belong to the genus 

 Polygonella of Mx, which I have called Lyonella. It is polygamous by the abor- 

 tion of the stamina.
