pears to be the S. volubilis, L. (119) ; there is also just the northern 

 Hypericum Oanadense, L. (218). 



A broad-leaved Stellaria (194) is perhaps a variety of the South 

 American S. cuspidata ; Drymaria cordata, Willd. (228) could not 

 fail to be in the collection ; but a less familiar plant accords with Gli- 

 nus Camhessedii of Fenzl, and no less vpith G. parvijlorus of Wallich 

 (271). 



The 'Malvacese of the collection are some common species of Sida, 

 viz. *S'. urens, L. (297), paniculata (203), carpinifolia (220), rhombi- 

 folia (296), and Elliottii, Torr. & Gray (176) ; Ifalvaviscus arhoreus, 

 Cav. (289) ; Malvastrum tricuspidatum, Gray (290, 291) ; Anoda has- 

 tata, Cav. (331); Ahutilon (Wissadula) periplocifolium, Don (151), a 

 form with narrow and tapering leaves, and slightly and bluntly pointed 

 carpels ; the " corolla flesh-color " according to the collector's memo- 

 randum ; also A. ( Wissadidd) mucronulatum (152), that is, Wissadida 

 mucronulata, Gray, Rel. Berland., mscr., & Torr. in Bot. Mex. Bound. 

 p. 39, the flowers of which are said to be " golden yellow." It is no. 

 3109 of Berlandier's collection, also from Tantoyuca. But if W. liirsu- 

 ta, rostrata, and other plants recently referred by Grisebach to A. peri- 

 plocifolium really belong to one species, it may well include the pres- 

 ent plant also, which is, perhaps, Sida hernandioides L'Her. There 

 is, finally, a true Ahutilon (161), the species undetermined for the want 

 of fruit, and the following : — 



Ahutilon notolophium (sp. nov.) : fruticosum ; foliis lato-cordatis acu- 

 minatis integerrimis supra puberulis subtus ramis calycibusque furfu- 

 raceo-tomentulosis saepius ferrugineis ; pedunculis axillaribus folium 

 subjequantibus et corymbosis ad apicem ramorum ; floribus magnis ; 

 calyce quinquangulato ; capsula (immatura hirsuta) polycocca, coccis 

 compressis truncatis muticis dorso toto alatis 4 — 5-spermis demum bi- 

 valvibus, ala bipartibili chartacea margine muricato-denticulata, denti- 

 bus fasciculo pilorum terminatis. — Hills at Tantoyuca, Mexico, Jan. 

 1831 ("flores lutei"), coll. Berlandier 743, 2163. — Leaves 3 to 6 

 inches in diameter. Peduncles 2 to 3 inches long, one-flowered. Ca- 

 lyx an inch long, apparently strongly 5-angled, or as if crested at the 

 base, 5-cleft. Petals an inch and a half long, broadly obovate, veiny. 

 Carpels more than 20, forming a depressed-globular umbilicate fruit of 

 an inch in diameter, separable at maturity, glabrous except on the 

 back ; the proper cell small (about 2 lines broad and 3 lines long), and 

 lunate, chartaceous, but the whole produced into a dilated crest or wing,
