APPENDIX. 39i- 



Nutt. found by ifte in North Carolina, which is manifestly 

 different not as a mere variety from E. coccinea. 



63. Melampyrum "^brachiatum, L. v. Schw. 

 Although unfortunately the specimens before me do not 



admit of distinguishing a flower, (being badly dried and 

 black,) there can be little doubt from the whole habit and 

 peculiarity of the capsule, (greatly resembling that of M. 

 cristatum,) that this constitutes a distinct new species of 

 Melampyrum. 



Stem terete, somewhat scabrous, naked below, branch- 

 ing by long, naked, adscendent, opposite or whorled 

 • branches, which subdivide into trichotomous whorls, with 

 two opposite leaves in the axills. Leaves about an inch long, 

 1-2 lines wide, attenuated into a thin petiole, margin en- 

 tire, rugose and scabrous on both sides. Capsules on short 

 peduncles from the axills of the floral leaves, which become 

 more and more crowded into a kind of spike towards the 

 summit of the branches, without bracteas as far as I can 

 distinguish. Capsule obliquely bent downward, acute, 

 containing two large, cylindric, oblong, yellow seeds, in 

 each cell. Height of the whole plant 6-8 inches. 



64. Gerardia tenuifolia ? Pursh, p. 422. 



The leaves are rather too broad and scabrous, but it would 

 scarcely admit of being considered different. 



XIV. CLASS TETRADYNAMIA. 



^5. Draba arabis, Nuttall, II. p. 63. 



Draba arabirans, Mx. so labelled in the collection by 

 Mr. Nuttall, and certainly with propriety. It is not, how- 

 ever, the plant so called by Pursh, as Mr. Nuttall clearly 

 points out, and very correctly calls that Alyssum, denta- 

 tum, see Nuttall, Gen. II. p. 63. A rare plant.
