preceding species ; the flowers smaller, apparently white or yellowish. 

 The bristly hairs on the forming fruit ai'e rather few, much longer 

 than the ovary, and all confined to its base. The floral leaves, in sim- 

 ple pairs, often show minute intei-posed stipules. 



Kellogia galioides, Torr. in Bot. S. Pacif. Ex. Exped. coll. 

 N. W. Amer. Phsenog. t. 4. — This interesting plant, which, we be- 

 lieve, was discovered in the northern part of California, has now been 

 collected by Dr. Brewer [and more recently by Dr. Torrey himself], 

 in the foot-hills of the Sierra. It is, as it were, an Asperula with 

 opposite leaves and scarious interposed stipules. 



Mach^ranthera (Hesperastrum ; ligulse steriles) Shastensis : 

 nana, e caudice perenni multicaulis, tomentuloso-canescens ; caulibus 

 1 - 2-cephalis ; foliis integerrimis obtusis, infei'ioribus spathulatis sub- 

 trinervatis, superioribus oblongis subamplexantibus ; involucri cam- 

 panulati squamis lanceolato-linearibus ssepius acutis, extimis apice 

 herbaceis, interioribus tenuioribus inappendiculatis ; ligulis "roseo-viola- 

 ceis " ? — Northern California, on Mount Shasta, at the height of 9,000 

 feet. Very little of this was found. It is a dwarf alpine plant (3 to 

 6 inches high, the lower leaves less than an inch long, the upper cau- 

 line successively smaller), with the aspect, styles, and generally the 

 character of 3Iachceranthera, except the perennial root and completely 

 neutral rays, or o? Aster, excepting the last-named particular. As it 

 has neither the peculiar appendages to the style nor to the anthers of 

 Lessingia and Corethrogyne, I cannot refer it to the latter genus, but 

 on the whole conclude to append it to Machceranihera. The ovaries 

 are scarcely compressed. Involucre 3 or 4 lines in diameter. 



Aster Bloomeri : depressus, casspitoso-diffusus ; ramis foliosis 

 apice monocephalis ; foliis parvis (3-6 lin. longis) oblongo-linearibus 

 imisve lineari-spathulatis sessilibus uninerviis aveniis hispidulo-scabris 

 et ciliolatis ; involucri hemisphasrici squamis subtriserialibus lineari- 

 lanceolatis acuminatis dorso vel apice herbaceis minute granuloso- 

 glandulosis laxiusculis ; ligulis pallide violaceis ? — On high slopes of 

 Mount Davidson, near Virginia City, Nevada, H. G. Bloomer. A pe- 

 culiar little species, to be ranked, perliap-^, with the Ericoidei, but not 

 obviou-ly related to any other. Stems tufted from a somewhat ligne- 

 ous caudex, tlie branches very leafy nearly to the heads ; the leaves 

 uniform. Heads about 4 lines in diameter, exclusive of the rays. 

 Appendages of the style subulate. Achenia pubescent. Pappus soft.
