lajara ; September. (638, Chili piquin " ; 639 ; 640 ; 642, " Mi- 

 rasol.") 



SoLANUM NIGRUM, Linn. Rio Blanco; June. (11.) — "Mora"; 

 the fruit is used in the treatment of erysipelas and sores generally. 



SoLANUM TORVDM, Swartz, — probably a form; no prickles seen. 

 A shrubby plant, with white flowers. Barranca, in shade. (lOG.) 



SoLANUM REFRACTUM, Hook. & Am. Bot. Beech. 304. " With 

 long stems hanging upon other plants ; leaves upon the ends of the 

 branches very different from those below," being pinnatifid, some 

 deeply so, while many of the lower are entire. It evidently climbs by 

 means of the short refracted prickles. Calyx often 6-8-toothed ; 

 white corolla-lobes and stamens 5 to 8 ; fruit globose, an inch and a 

 half in diameter or more. Barranca. (108.) — S. hicorne^ and var. 

 angusti folium, Dunal in DC. Prodr. 13. 232, are evidently forms of 

 this. 



SoLANUM PiLiFERUM, Benth. PI. Hartw. 68. Doubtless also S. 

 Andrieuxii, Dunal, 1. c. 165. Rio Blanco, in shaded ravines; July. 

 (186.) — "Flowers open only at night, the corolla either light or 

 dark drab with some brown lines ; fruit egg-shaped, greenish yellow, 

 with an apple-like odor and pleasant taste. It is much eaten, is sold 

 in the markets, and a preserve is made of it." 



SoLANUM Teqdilense, Gray, n. sp. Leptostemonum, crebiter 

 ochraceo-tomentosum ; caule (toto herbaceo ?) valido aculeis subulato- 

 acicularibus rectis (lin. 3-4 longis) crebris horrido ; foliis ovalibus 

 pinnatifido-dentatis vel sinuatis basi cordulatis utrinque subcequaliter 

 pannosis, majoribus 10-18-pollioaribus, costa venisque primariis parce 

 aculeatis ; pedunculis unifloris siibfasciculatis petiolo brevi baud longi- 

 oribus raox recurvatis ; calyce 5-fido inermi (lobis ovatis obtusis) cum 

 corolla 5-partita (lobis ovato-lanceolatis subsemipollicaribus intus 

 albis) extus creberrime pannoso-tomentoso ; bacca globosa rubra pilis 

 stellatis subpungentibus tecta calyce vix accreto stipata. — Tequila, 

 along rocks and fences among the hills. (424.) A remarkable spe- 

 cies, of the type of S. scabridum, which I do not find described. 



SoLANUM ? Probably a very narrow-leaved variety of S. 



Jamesii, Torr., or of ^S*. append! cidatum, Schlecht. Rio Blanco, near a 

 small stream; September. (611.) — " Flowers white ; tubers white, 

 firm, and nutty in flavor." 



SoLANUM CALLiCARPE^FOLiUM, Linn. Guadalajara, on hillsides ; 

 September. (625.) 



NicOTiANA PLUMBAGINIFOLIA, Viv. Barranca, in the shade of 

 rocks. (110.)
