24. Baptisia Tex an a, the color of the corolla of which is not mentioned 

 in the singular specific character, is founded on a branch of either B. austral is 

 or leacantha, the two commonest of species. 



25. Cassia Texan a is C. cham&cristoides, Collad. (C. cinerea, Cham, and 

 Schlecht.) enumerated in the Botany of the Mex. Bound. Survey, p. 59. It 

 is No. 2427 and 2429 of Berlandier's collection. 



26. Hoopesia arborea, n. gen. and sp. is made up of a flowering speci- 

 men of Cercidium Texanum, Gray, a fruiting one of Acacia flexi caul is, Benth. , 

 and a sterile branchlet of Acacia rigidula, Benth. The character " semen re- 

 miformis " is, like the gender, an oversight. The above are the materials in 

 herb. Durand. Those of the herbarium of the Academy lack the Acacia rigi- 

 dula, and have only broken fragments of the Cercidium. 



27. Acacia Sabeana is Leucana retusa, Benth., in PL Wr. 1, p. 64 ; a 

 species not easy to mistake. 



28. Acacia Durandiana is A. Greggii, Gray, PI. Wright, 1 and 2 ; 

 Bot. Mex. Bound., &c. 



29. Acacia Nueciana is founded on a miserable fragment of Pithecolo- 

 bium brevi/blium, Benth., in PI. Wr., 1, p. 67. 



30. Mimosa calcarea is Strombocarpa (Prosopis, Benth.) cinerascens, Gray, 

 PI. Wr., 1, p. 61 ; Torr. Bot. Mex. Bound. Surv., p. 60 where it should have 

 mentioned that it is Berlandier's Nos. 2013 and 3143. 



31. Desmanthus pedunculatus is D. velutinus, Scheele, abundant in 

 all collections. 



32. Desmanthus rhombifolius is D. reticulatus, Benth., the characters 

 which distinguish the species quite omitted. 



33. Crataegus T e x a n a is C. tomentosa var. mollis, Gray, Man., and C. sub- 

 villosa, Schrader, not to mention other names. 



34. Gaura triangulata is G. tripetala, Cav. ; Gray, PI. Wr., 1, p. 72, 

 mixed with some G. coccinea. 



35. Oenothera Lampasana is just intermediate between Wright's No. 

 199, (E. Greggii var. pubescens, Gray, PL Wr., 1, p. 72, and his No. 1076, (E. 

 Hartwegi var. approaching Fendleri. So that, instead of a new species, a 

 farther reduction than I had indicated in PL Wr., 2, p. 58, &c. is indicated. 



36. Oenothera L e o n a. the glabrous calyx excepted, accords throughout 

 with (E. rhombipetala of the Flora of North America, and I presume with 

 Nuttall's plant, which I have not access to at present. What Mr. Durand 

 takes for (E. rhombipetala (Texas, Dr. Linsecom), also Lindheimer's No. 56 and 

 Berlandier's No. 1842, with the calyx hirsute with very long and spreading 

 hairs, the petals rhombic- ovate, but obtuse and erect pods, I take to be (E. 

 bifrons of Don and Hooker, probably quite distinct, although some forms are 

 questionable. 



37. Mentzelia petiolata is a not uncommon form of M. oligospermia, 

 Nutt. 



38. Saxifraga Tex an a: no specimen extant. 



39. Cymopterus macrorhizusis C. mentanus, Nutt., and the Texan 

 plant so named in PL FendL, p. 56 and PL Wright, 1, p. 79, the latter from 

 Austin, Mr. Buckley's own locality. I had recorded the fact that it agreed 

 very well with Nuttall's original specimens in the Hookerian herbarium. 



40. Eurytaenia m a c r o p h y 1 1 a, as it appears to me, is E. Texana with 

 1862.]
