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

 Plantce Lindheimeriana above citcd, to distinguish Planchon's I^. hudsonioidcs ; but 

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

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

 Southern Texas, and by Dr. Edwards, Dr. Grcgg, &c., in Northcrn Mexico. — Stems 

 4 to 10 inches long, oftcn rather ligneous ncar thc thickencd, "woody root, or with a 

 woody crceping rhizoma. Lcavcs an inch or less in diaraetcr, mostly shortcr than 

 the petiole, usually strongly apiculate at the emarginatc apcx: thc sctiform stipules 

 3 or 4 lines long. Peduncles as long as the petiole, bibractcolate ncar thc flowcr ; 

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

 cincreous, with 2 or 3 strongly tubcrculate-rugose seeds in each cell. — This very

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

 the deeply two-cleft leaflets. No. 91 of Pl. Fendleriance, which was so callcd, is 



only O. violacea. 



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

 crassa perpendiculari assurgentibus petiolis pedunculisque hirsutis ; foliolis glauces- 

 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 cdcntulis ; stylis brevissimis hirtclUs ; 

 capsuh^ elongata canescente, loculis 9- 12-spermis. — Between Tcxas and New 

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

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

 slender, assurgent stems, wiry and slightly ligncous 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) pctals. Stamcns 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.
