The following paper was read by title : 



A LIST OF PLANTS COLLECTED BY MISS MAEY B. CROFT, 1884- 

 ^85, AT SAN DIEGO, TEXAS, NEAR THE HEADWATERS OF 

 THE RIO DULCE, BY N. L. BrITTON AND H. H. RUSBY. 



The species here enumerated were collected by Miss Croft 

 during the years 1884-1886 and sent to Dr. Rusby for deter- 

 mination. His absence in South America has prevented their 

 examination until the present time. 



RANUNCULACE^. 



19. Anemone decapetala, L., var. heterophylla (Nutt.) 

 {A. heterophylla, Nutt., mss.; Wood). We are unable to find 

 any characters which would entitle this plant to specific rank. 

 Indeed, our specimens show every gradation in leaf-form 

 from the linear lobes of the typical A. decapetala to the 

 nearly entire ones of the variety. A specimen collected by 

 Merrill, in Robertson Co., Texas,' has both forms on the same 

 plant. As here recognized, the variety extends east into Ala- 

 bama (Buckley) and occurs also in South America, Cuming's 

 specimens from Valparaiso in Herb. Torrey consisting of both 

 type and variety. 



BERBERIDAOE^. 



87. Berleris trifoUata, Moric. 



PAPAVERAOE^. 

 98. Argemone Mexicana, L. 



CRUCIFER^. 



88. Vesicaria Fendleri, Gray. 



90. Vesicaria lasiocarpa, Hook. 



93. Draba platycarpa, T. & G-. 



94. Sisijmhrium pinnatum (Ell.), Greene. {S. canescens, 

 Nutt.) 



91. Lejyidium intermedium, Gray. 



VIOLACE^.
