 Border of Post-Oak woods, on the Colorado, Texas ; May. — I had endeavored, in 

 Plantce Lindheimeriance above cited, to distinguish Planchon's L. hudsonioides ; but 

 now, with the original specimens before me, I am unable in any wise to do so. Ber- 

 landier's plant is at most a state of L. multicaule. 



OXALIDACE^. 



74. OxALis dichondr,5;folia (sp. nov.) : cinereo-pubescens ; caulibus e basi cras- 

 sa sufFruticosa diffusis vel decumbentibus foliosis ; foliis unifoliolatis longe petiola- 

 tis ; foliolo rotundato cordato apice truncato-retuso sinu mucronati-cuspidato ; sti- 

 pulis setaceis ; pedunculis axillaribus solitariis unifloris ; sepalis e basi subcordata 

 lanceolatis corolla flava dimidio brevioribus ; filamentis glabris ; stylis pilosis ; ova- 

 rii loculis 2 - 3-ovulatis ; seminibus tuberculatis. — Turkey Creek to the prairies of 

 the San Felipe, and on the Rio Grande, Texas. Also gathered by Berlandier in 

 Southern Texas, and by Dr. Edwards, Dr. Gregg, &c., in Northern Mexico. — Stems 

 4 to 10 inches long, often rather ligneous near the thickened, woody root, or with a 

 woody creeping rhizoma. Leaves an inch or less in diameter, mostly shorter than 

 the petiole, usually strongly apiculate at the emarginate apex: the setiform stipules 

 3 or 4 lines long. Peduncles as long as the petiole, bibracteolate near the flower ; 

 the bractlets like the stipules. Petals nearly half an inch long. Capsule subglobose, 

 cinereous, Avith 2 or 3 strongly tuberculate-rugose seeds in each cell. — This very 

 curious species does not resemble any other with which I am acquainted. 



f O. VESPERTiLioNis, Tovr. 8f Gray, Fl. 1. p. 679. Hills of San Pedro River. 

 This is at once distinguished from O. violacea by the narrow and divaricate lobes of 

 the deeply two-cleft leaflets. No. 91 of PI. Fe^idleriana, which was so called, is 

 only O. violacea. 



X O. Wrightii (sp. nov.) : caulescens, trifoliolata, exstipulata ; caulibus e radice 

 crassa perpendiculari assurgentibus petiolis pedunculisque hirsutis ; foliolis glances- 

 centibus brevissime petiolulatis basi truncatis dilatatis profunde obcordato-bilobis hir- 

 to-ciliatis junioribus hirsutis, lobis late obovatis ; pedunculis solitariis unifloris raro 

 bifloris folio longioribus ; staminibus glabris edentulis ; stylis brevissimis hirtellis ; 

 capsula elongata canescente, loculis 9- 12-spermis. — Between Texas and New 

 Mexico: coll. of 1851. — Root simple and fusiform, perpendicular, 6 inches long or 

 more, lignescent but rather fleshy, reddish. From its summit spring a number of 

 slender, assurgent stems, wiry and slightly ligneous at the base, clothed, like all 

 other parts of the plant when young, with appressed hirsute hairs. Leaves of a 

 pale cinereous hue. Leaflets dilated, much broader than long, 3 or 4 lines wide, 

 somewhat truncate at the base, the very broad notch reaching beyond the middle, 

 so as to form two divergent, broadly obovate lobes. Fructiferous peduncle an inch 

 long, and bearing a pedicel (or rarely a pair of pedicels) of nearly the same length. 

 Sepals lanceolate-oblong, obtuse, not glandular, 2 lines long, about half the length 

 of the (apparently purple) petals. Stamens conspicuously monadelphous. Styles 

 much shorter than the ovary: stigmas truncate. Capsule from one half to two 

 thirds of an inch in length. Seeds strongly rugose.
