REMARKS 



ON SOME OF THE PLANTS OF THE CATALOGUE. 



(1.) The Aster alatus described below, is the species generally referred 

 to the A. prenunlhoides, 'WiMdi. I subjoin the characters of Willdenow's 

 plant as given by Sprengel, and cannot help thinking that a slight exami- 

 nation will satisfy any one, that it is a distinct species : 



Aster alatus, stem angled, flexuous, glabrous below, pubescent above: 

 leaves ovate, slenderly acuminate, tapering to the petiole, sharp serrate, 

 scabrous above, glabrous and paler beneath, serratures sub-mucronate ; 

 upper leaves lanceolate sub-entire; petioles winged, clasping: scales of 

 the calyx linear, acutish, reflex-spreading at the apex. 



Inflorescence, a loose terminal corymbed panicle, peduncles about 

 1-flowered, bracted. Calyx sub-ovate, flowers large, rays numerous, 

 narrow, lilac purple; disk yellow, becoming brownish, receptacle flat, 

 naked, sub- alveolate ; seeds oblong, minutely pubescent; egret pilose, 

 hairs finely scabrous, root fibrous. Damp shady grounds, Ju. 12-24 i. 



Aster prenanthoides , Willd. stem branching, branches fastigiate, pilose : 

 leaves clasping, sub-cordate-lanceolate, serrate in the middle: scales of 

 the calyx lanceolate, elongated, lax. A. longifolia, Lk? 



(2.) The Euphorbia Eatonii of the catalogue, is the Fi. peplus of our 

 American botanists, but distinct from the European species, as a com- 

 parison of the following descriptions will show. I have suggested the 

 above name for our plant, in remembrance of an old and valued friend, 

 long since dead, T. Dwight Eaton, formerly of the Rensselaer Institute, 

 N. Y. an assiduous and enthusiastic student of nature. 



Euphorbia Ealonii, umbel 3-cleft, dichotomous: involucels, heart- 

 reniform, sessile : lower cauline leaves obovate, petiolate, sub-crenulate, 

 undulate; upper ones sessile, cordate and reniform, entire: fruit 3 

 smooth, ovoidal, 1-seeded capsules; arils cinereous pitted. 



Stem branching, floral leaves large, calycine involucre often 4-cleft 

 or lobed with lobes, bicuspidate. Sandy meadows, flowers light green. 

 May,©? 12-18 i. 



Euphorbia peplus Linn, umbels 3-cleft, rays dichotomous: bracts 

 ovate, involucral appendages, bi-cuspidate : leaves obovate, obtuse, very 

 entire, emarginate: capsules angled, keeled. 



(3.) Phlox revoluta, glabrous, stem erect, sub-simple : leaves sub- 

 sessile, scabrous and revolute on the margin, coriaceous, paler beneath; 

 lower ones lance-linear, acute at each end ; upper ones lanceolate, rounded 

 at the base: divisions of the corol obovate, slightly crenulate: divisions 

 of the calyx lanceolate, acute, unawned. 



Stem slightly scabrous at the top; corymb sub-fastigiate, few flowered : 

 pedicels sub-scabrous; divisions of the calyx half as long as the corol. 

 Easily distinguished from the other species of this region by its thick, 

 shining leaves. Damp woods, flowers light purple, June, X 12-18 i.
