gioribus demum patentissimis ; foliis alternis angustissime linearibus 

 margine glandulis brevissime stipitatis seu dentiformibus creberrirae 

 ciliolatis ; glandulis stipularibus parvis ; sepalis oblongo-lanceolatis 

 acutis margine rariter vixve glanduloso-denticulatis ; petalis ut videtur 

 llavis calyce subduplo longioribus, ungue lato ima basi utrinque uniden- 

 tato intus appendice squamiformi parvo aucto ; sinubus inter stamina 

 nu Us ; antheris lineari-oblongis ; stylis 3 gracilibus ; stigmatibus mini- 

 mis. — California, near Clear Lake, May, 1872, H. N. Bolander. — 

 This is another trigynous Linum, related to L. spergulinutn and L. mi- 

 cranthum, with flowers not larger than those of the latter ; distin- 

 guished by the thickly set glandular ciliation of the leaves. A minute 

 pubescence appears on the lower part of most of the internodes. 



Dalea Hallii. Hcrbacea ; caulibus gracilibus e radice perenni 

 fusiformi decumbentibus laxe ramosis pube adpressa minuta cinereis ; 

 foliis pinnatim trifoliolatis glabratis ; foliolis linearibus acutis rariter 

 glandulosis petiolo haud complanato 2 — 3-plo longioribus ; spica sub- 

 sessili oblonga densiflora ; bracteis ovato-lanceolatis sericeo-pubescenti- 

 bus calycem haud superantibus ; calyce villoso, dentibus e basi lata 

 subulato-setaceis tubo subglandulifero longioribus ; corolla flava, alis 

 vexillum flabelliforme multo superantibus. — On limestone, Dallas, 

 in Northeastern Texas, Elihu Hall, 1873, no. 132. — This is nearly 

 related to D. trifoliolata Moricand, of Mexico, which is probably D. 

 prostrata Ortega ; but much more slender, brandling, with narrower 

 leaflets and petiole, smaller flowers, shorter bracts, and a minute close 

 pubescence except on the bracts and calyxes. 



Hosackia Torreyi. Molliter nunc sericeo-pubescens, inferne 

 glabella ; stipulis subulato-lanceolatis scariosis ; foliolis 7-10 obovatis 

 oblongo-ovatis vel fol. superiorum lanceolato-oblongis; pedunculis foli- 

 um superantibus ; umbella 3 -7 -flora bractea unifoliolata stipata ; calycis 

 villosi dentibus subulatis tubo requilongis ; vexillo saturate luteo, alis 

 c-arinaque albis. Sierra Nevada, California, along the shady banks of 

 streams, at the elevation of 4,000 feet and upwards ; common from 

 Clark's to the Yosemite Valley, where it has been collected by Bridges, 

 Torrey, Bolander, and by myself. — Var. Nevadensis : pube tenuiori ; 

 bractea 3-foliolata ; floribus minoribus. Near Donner Lake, Torrey. 

 On account of the very neat particolored flowers, this species would 

 be attractive in cultivation. I had at first (overlooking the stipules) 

 taken it for a small-flowered variety of H. grandiflora, and afterwards 

 supposed it might belong to the little-known H. oblongifolia Benth.
