as bracts, and the only species heretofore recognized as an annual ; 

 M. unduluta, with its larger forms (often confused with the foregoing), 

 the leaves of which are seldom at all undulate, and the bracts are more 

 rigid or foliaceous and less blunt ; and the following, which is most 

 like M. Douglasii on one hand and M. undidata on the other. 



MoNARDELLA Brewehi : annua, hurailis, puberula ; foliis oblongis 

 vel spathulatis penninerviis petiolatis ; involucri bracteis latissirae ova- 

 tis subulato-acuminatis plerisque tenuibus 5— 7-nervatis vel quintupli — 

 septuplinerviis calyces tubulosos baud superantibus ; dentibus calycis 

 obtusiusculis ; corolla rosea longius exserta. — Corall Hollow on the 

 dry eastern side of the Californian Coast range south of Monte Diablo, 

 Brewer. Scantily collected, apparently a very distinct species : the 

 specimens little over a span in height. Calyxes merely soft-pubescent ; 

 the teefh rather broad, wholly pointless. Nerves of the involucral 

 bracts about 5 from the base, and one or even two pairs from tlie mid- 

 nerve near the base, converging to the pointed apex. Corolla 3 or 4 

 lines longer than the calyx. — The two perennial and more or less 

 sufFruticose species are found in California, M. odoratissima only in 

 the mountains, M. villosa in the low country and farther south, and 

 under several forms : among them the var. leptosiphon, Torr., passes 

 into var. ylabella {31. Shellonii, Torr. in Durand, PI. Pratten. ?) which 

 has smaller leaves and heads, no villosity at all, and scarcely any 

 pubescence. 



PoGOGYNE (Hedeomoides, stam. fert. 2) serpylloides {Hede- 

 oma .^ serpylloides, Torr. Bot. Whippl.) : pusilla ; foliis spathulatis vel 

 . obovatis ; verticillastris paucifloris s«pe distantibus ; dentibus calycis 

 bracteisque nudiusculis parce hirsuto-ciliatis, 2 superioribus paullo 

 longioribus corollam adgequantibus ; filamentis 2 sterilibus rudimento 

 antherae capitatis ; stylo superne parcissime hispido ; stigmatis lobis 

 ina^qualibus. — Martinez, J. M. Bigelow. Oaklands, Marsh's Ranch 

 near Monte Diablo, Arroyo Grande, San Juan near Monterey, &c., 

 Brewer, Bolander. Plant from 2 to 5 inches high, exhales a strong 

 scent of Pennyroyal. Corolla blue or purple-violet, very small. 

 Flowers in some specimens sparse in the manner of Hedeoma, in many 

 of the older ones numerous and interrupted-spicate as in Pogogyne. 

 Calyx deeply cleft, not bearded in the throat. If it were so, the plant 

 would manifestly belong to Hedeoma. But it is a clear congener and 

 very near relative of Pogoggue zizyphoroides, Benth. (sparingly col- 

 lected in flower by Mr. Bolander, with larger and roundish leaves).
