mamiia fumariaefolia. Sweet, was. collected near Saltillo, with smaller Unil 
flowers, (l^r inch in diameter,) and'near Rinconada, with larger ones, (3 jus pi 
inches in diameter;) an interesting plant, the eastern representative of the % sen 
Californian Eschscholtzia , but perennial, with a small torus, a different .ers.

I cannot omit to introduce here a beautiful shrub discovered on the Hasty 
rocks about Agua Nueva and Buena Vista by Dr. Gregg. Depending jt can 
upon Don’s characters of Cowania as correct, I must consider this plant ra of 
as the type of a new genus, which I have great pleasure to dedicate to itlps. 
indefatigable discoverer, my friend Dr. Josiah Gregg, whose name has 
already been frequently mentioned in these pages. 51 Greggia rupestris g Tt L 
is a lovely; sweet-scented shrub, with flowers resembling roses in shape 
and color, so that Dr. Gregg was induced to name it the “ Cliff rose.” Up 0n 
North and northeast of Monterey we reach the lower country, and with Tie m , 
it a different vegetation ; here is the home of the shrubby JGzssieae (Par- m b( 
kinsonia , Gasp area, etc.,) and Mimoseae; Sophora, Diospyros , some spe-j^ 
oies of Rhus and Rhamnus are common here, as well as a climbing yet-» :r j cau 
low-flowered Hiraea , while another erect red-flowered species grows on >m 
the table-lands near Parras. One of the most beautiful shrubs of that 
district is Leucophyllum texanum, Benth., with its whitish tomentose^ 
leaves and sweetscented blue flowers. It is common from San Antonio, 
in Texas, to Monclova, and from Cerralbo to Camargo, but is not seen 
on the table-lands.
