111. Hoffmanseggia oxycarpa Hcuth. Western Texas, collected in l!^8R. This 



seems to be a very nue npecies, having been reported only by Wrhjht from 

 Texas in 1851, aud by the botanists of the Mcx. Bound. Surv. from extreme 

 western Texas. 



112. Hoffmanseggia atricta Beuth. Corpus Christi (Nuocos couuty) and Chenate 



Mountains (I'rcsidio county). 



113. Parkiusoiiia aculeata 1j. Hidalgo (Hidalgo county). 



114. Parkinsonia Torreyaiia Watson. Hidalgo (Hidalgo county). The finding of 



this species along the lower Kio Grande was unexpected, as it has heretofore 

 seemed restricted to southern aud westerji Arizona aud contiguous Califor- 

 nia. Its representative in the Rio Grande Valley is 1'. Jloridu Watson, aud 

 they were thought to be as distiuct in range as in characters, although the 

 western type was for a time confused with that of the Kio Grande. Nealley's 

 specimens, however, collected in both ll()wcr and fruit, show the character- 

 istic iulioresccnco, the thick-edged pod with its double groove, and the leaf- 

 lets of r. Toireyuna. It is possible that the two forms should not be con- 

 sidered distinct species. 



115. Cassia bauhiiiioides Gray. Koma (Starr county). 



116. Cassia nictitans Jj. Chenate Mountains (Presidio county). 



117. Cassia procumbeiis L. I'eua (iJuval couuty). This is a variable tropical- 



American species, lirst found in Texas by Jierlaiidier (no, 2427), and after- 

 ward by the Alex. Bound, Siirv. lierlaudier's specimen is larger than the 

 typo. Nealley's specimens conform better in size, but have the decidedly 

 larger stipules aud Howers of the lierlandier specimen. In a species so 

 widely extended and variable such variation counts for little, 



118. Cassia pumilio Gray. Chenate Mountains (Presidio county). 



119. Desmanthus depressus Huuib. & Bonpi. iSaute Maria (Cameron county). 



This species is abundant enough in sontlun-n Florida and the West Indies, also 

 from northern Mexico southward, but has only occasionally been collected in 

 Texas. The present collection indicates that it grows in abundance in Cam- 

 eron county, the most southern coast county of Texas. 



120. Desmanthus reticulatus Uenth. Corpus Christi (Nueces couuty) aud Pena 



(Duval county). 



121. Mimosa Berlandieri Gray. Brazos Santiago. This rare species seeuis to 



have been collected heretofote only by Schott, along the lower liio Grande 

 in Texas, and by. Berlandier (no. 3146) near Matamoras, on the Mexican side 

 of the river. Both of these discoveries were reported in Bot. Mex. Bound. 

 Survey (185i)). Nealley's station, from wliich he has brought conside- 

 rable material, is just north of the mouth of the Rio Grande, 



122. Mimosa biuucifera Bentb. Southwestern 'i'exas. Collected in 1887. 



123. Mimosa dysocarpa Boutli. liimpia canon (Presidio county). This species 



was collected by Chas. U'liyht in his New Mexican collection of 1851, and by 

 Emora in the Mexican Boundary Survey. Since then, it was collected iu 

 1874 in Arizona by liuthrock, aud by Fritujle in bis Chihuahua collections. 

 Witli the present collection in western Texas we have the range of this 

 species extimdiug throughout northern Mexico and adjacent parts of the 

 United States. 



124. Mimosa Lindheimeri Gray. Itoma (Starr couuty).
