OF ARTS AND SCIENCES : MAY 30, 1865. 621 



capsiila obovato-globosa, stipite (vix calycem superante) styloque bre- 

 vissimis ; seminibus liBvibus. — Nevada, near Carson City, Dr. C. L. 

 Anderson. The foliage nearly as in C. tenuifolia, but a more deli- 

 cate plant, only about a span high, the flowers and pods only half the 

 size, and the stipe much shorter than in any other species, not half a 

 line in length. Dr. Anderson also sends C. longipes, Torr., from Ne- 

 vada. 



LiNUM § Hesperolinon. Spec. 3 Californicse, annuae, trigynae, 

 capsulis 6-locellatis ; unguibus petalorum basi tri-appendiculatis. Styli 

 a basi liberi, stigmatibus parvis. Dentes inter stamina nulli. Sepala 

 ovato-lanceolata, herbacea, immarginata, vix uninervia. Floras brevi- 

 pedicellati. Folia angustissime linearia, subfiliformia, plerumque al- 

 terna. Caulis inferne simplex, strictus. 



LiNUM Californicum (Benth., PI. Hartw. p. 299) : glabrum ; 

 caule superne in cymam effusam repetito-dichotomam soluto ; glandulis 

 stipularibus geminis ; sepalis margine subglandulosis ; petalis albis 

 roseisve. — Dr. Torrey, in Bot. Mex. Boundary, first noticed the trigy- 

 nous character, which it shares with the following new Californian 

 species. All three exhibit three little teeth or auricles at the base of 

 the claw of the petals, one on each margin and one adnate to its inner 

 face. The coincidence of these characters invalidates the technical 

 distinction of the genus Reimoardtia, — in which, however, the teeth 

 or appendages of the petals according to Planchon (in Lond. Jour. 

 Bot. 7, p. 522), or two of the three according to Bentham and Hooker 

 (Gen. PI. p. 243), are dorsal. 



LiNUM congestum: glandulis stipularibus inconspicuis; caule foliis- 

 que fere glabris ; floribus in ramis brevibus suberectis capitato-glome- 

 ratis ; sepalis pubescentibus eglandulosis ; petalis roseo-purpureis ; 

 stigmatibus brevibus vix incrassatis. — Marin County, coll. H. N. Bo- 

 lander. Flowers about the size of those of L. Californicum. 



LmuM Breweri ( Gray in Proceed. Calif. Acad. 1. c.) ; glabrum ; 

 caule exili apice confertim paucifloro ; foliis raro oppositis ; glandulis 

 stipularibus conspicuis ; sepalis margine glandulosis ; petalis aureis ; 

 stigmatibus acutis. — Dry hills of the Monte Diablo range. Plant only 

 a span high, in flower ; the fruit not seen. 



There might seem to be a fourth species of the group, L. trisepa- 

 lum, of Kellogg, in Proceed. Acad. Calif. 3, p. 42, fig. 10. But his 

 plant is Helianthemum scoparium, Nutt. ! And his L. decurrens is 

 evidently L. perenne.
