76. Eritrichium angustifolium, Torr. in Pacif. R. R. Rep. 5, p. 

 363. Accords with no. 500 of Coulter's Californian collection, which 

 is referred to this species by Dr. Torrey. No. 85 of a former collec- 

 tion of Xantus, made in the State of California, is a diiferent species, 

 near to or a variety of S. crassisepaliim, Torr. 



77. BuDDLEiA CROTONOiDES (sp. nov.) : tomento albido denso; 

 foliis e basi subcordata ovato-oblongis sen ovato-lanceolatis sensim acu- 

 minatis vel acutatis creberrime crenulatis, venis subtus prominulis reti- 

 culatis ; ramis teretibus ; panicula densa pyramidata ; capitulis flori- 

 busque tomentosis sessilibus ; corolla calycem vix superante. — Frutex. 

 Folia 3 - 4-pollicaria, dense ac moUiter tomentosa, tomento albo in cos- 

 ta venisque mox fulvello, venulis subtus conspicuis versus margines 

 Isete reticulatis. CoroUie sicut calyces extus dense tomentoste. — Re- 

 lated to B. Humholdtiana and B. cordata, but distinct in the woolliness, 

 the terete branches, &c. The tomentum probably falls with age from 

 the upper face of the leaves. 



78. EusTOMA EXALTATUM, Griseb. in DC. Prodr. 9, p. 51. 



79. QuAMOCLiT cocciNEA, Moench. 



80. Ipom^a (Pharbitis) Nil, Roth. 



81. Ipom^a sinuata, Ort. A form with the divisions of the leaves 

 nearly entire. 



82. Jacquemontia abutiloides, Benth. Bot. Voy. Sulph. p. 34. 



83. EVOLVULUS ALSINOIDES, Linn. 



84. SoLANUin EL^AGNiFOLiuM, Cav. Ic. t. 243 ; Dunal in DC. 

 Prodr. 13, p. 290. S. Hiridsianum, Benth. 1. c. 



85. Phtsalis glabra, Benth. Bot. Voy. Sulph. p. 39. But the 

 leaves are not thickish. 



86. Datura discolor, Bernh. ; DC. Prodr. 13, p. 541. D. Tho- 

 masii, Torr. in Pacif. R. R. Rep. 5, p. 362, & Bot. in Mex. Bound. 

 Surv. p. 155. Strafhonia Curassavica, &c., Herm. Par. Bot. p. 233, 

 cum ic. Cinereo-pubescens. Corolla quam D. Stramonii longior. 

 Capsula mox nutans, aculeis gracilibus aequalibus pubescentibus ultra- 

 pollicaribus horrida. — I have little doubt that this is the "West Indian 

 D. discolor, although the name is not appropriate to it. The plant of 

 Professor Thurber from Corralitas, mentioned by Dr. Torrey, is, I sup- 

 pose, D. quercifolia, H. B. K., which has also been collected by C. 

 Wright (no. 527) and others, on the Rio Grande in New Mexico. 

 This bears an erect fruit, the spines of which are unequal (the larger 

 an inch or more in length), compressed, and with dilated bases, gla- 

 brous or nearly so.
