which, however, it has longer and narrower leaves. Fort Miller, on the banks of 

 St. Joaquin river, August. 



HOSACKIA Heermannii, nova species. H. decumbens, var. glabriuscula? Hook, and 

 Arn. in Torr. & Gray's Fl. "Vol. i. p. 324. Suffrutex sat regulariter ramulosus, oin- 

 nino puberulus, li-2-pedalis. Ramuli in axillis umbelliferis oriundi internodiis 

 foliorum fere longitudine. Folia imparipinnata, foliolis 3-5 alternantibus, rhomboi- 

 deo-ovatis acutis mucronulatis pubescentibus, stipulis minutis rhomboideis lanugine 

 alba celatis, in quoque fere axillo umbellam gerentia. Umbellarum pedunculi rachidis 

 folii fere longitudine, 2-4-6-flori foliolumque solitare ferentes. Flores subsessiles. 

 Calyx campanulato-tubulosus pubescens, laciniis acutissimis. Corolla parva flava, 

 petalis gracilibus obtusis apice fusco-purpurascentibus. Leguraen pubescens, pen- 

 dulum, incurvum, rostro subrefracto subulato apice uncinate vixque dimidia totius 

 leguminis longitudine. Semina 1-2. Ab H. decumbente distinguitur forma ramo- 

 siore ac pubescentia densiore, foliis mucronulatis, stipulis haud spinosis, umbellarum 

 pedunculis multo brevioribus, flore minori apice purpurascenti leguminibusque ecari- 

 natis. 



Suffruticose, pretty regularly branching, softly pubescent throughout, l?-2 feet high; 

 branchlets, with internodes scarcely as long as the leaves, arising in umbelliferous axils. 

 Leaves impari-pinnate. Leaflets 3—5 rhombic ovate, acute, mucronulate, mostly alter- 

 nate. Stipules minute, rhombic, tomentose ; almost every axil bearing a stipitate um- 

 bel shorter than the leaf, 2-4-6-flowered with an oval bract in it. Flowers small, sub- 

 sessile, yellow with purplish tips. Calyx tubulate-campanulate. Legumen 1-2 

 seeded, pubescent, pendulous, incurved, with a subulate uncinate and somewhat re- 

 fracted rostrum. Differs from H. decumbens by being more branched and pubescent, by 

 mucronate leaves, stipules not spinose, peduncles of the umbels considerably shorter, 

 smaller flowers with purpurascent tips, and by legumes not carinate and mostly 

 one-seeded. 



ONAGRACE^E. 



(ENOTHERA Lindleyi, variety with light yellow petals and a violet spot above 

 the middle. Capsules linear, attenuate at each end. Fort Miller, July. 



CAPRIFOLIACEtE. 



SAMBUCUS velutina, nova species. Frutex 5-6-pedalis, exceptis foliorum su- 

 periori superficie glaberrima floribusque velutino-tomentosus. Foliola 5-7 ovato-lan- 

 ceolata, basi obliqua semisubcordata in lateralibus, acuta, argute serrulata, dentium 

 apice subscarioso, supra nitida et in sicco minute corrugata. Corymbus parvus
