MR. HAEl'WEG'S JOUllNAL OF A MISSION TO CALIFORNIA. 217 



XXIII. — Journal of a Misswn to California in Search of 

 Plants. By Mr. Theodor Ilartweg, in the service of the 

 Horticultural Society, Part IV., continued from Vol. II., 

 p. 191. 



(Received June 6, 1848.) 



"With January the rains set in unusually severe ; the Salinas and 

 other rivers, which are fordable during ordinary seasons, have 

 now become impassable. 



The first indications of the returning spring I observed in the 

 flowering of Garrya elliptica, Berberis aquifolium, Ribes specio- 

 sum, R. malvaceum, Arctostapliylos, Nos. 158, 159, and 160; 

 Vaccinium, No. 157, a dwarf shrubby Prunus (No. 162), with 

 white pendulous flowers, and Ornithogalum, No. 163. 



When the weatlier permitted it, I continued my rambles on 

 foot in the mountains of Monterey, and discovered on the western 

 declivity, within two miles of the seashore, a species of Pine 

 which I had not found previously. The leaves are two in a 

 sheath, three to five inches long; cones in clusters of four to 

 seven, oval, three inches long by two broad, of a reddish brown 

 before they are perfectly ripe, then changing into light brown ; 

 scales pyramidal, terminating in an ash-grey sharp point. The 

 trees attain no great elevation, averaging twenty feet, rarely 

 thirty, with a stem of twelve inches in diameter ; they are con- 

 fined to half a square mile, and like P. insignis, by which they 

 are surrounded on all sides, thrive in coarsely decomposed 

 granite. This species, which appears to be new, I have named, 

 in compliment to Thomas Edgar, Esq., the Society's Treasurer, 

 Pinus Edgariana. 



In the same locality with the above Pine, I observed a Cypress 

 (Cupressus, No. 166) with smaller cones than C. macrocarpa, 

 of which it seems more than a variety, being a stunted shrub six 

 to ten feet high. 



Returning by a different route, through a thick brushwood of 

 Arctostaphylos and Ceanothus, I found on the steep acclivity, in 

 a shaded dell, a Rhododendron, without seeds or flowers, form- 

 ing a shrub five feet high, well beset with flower-buds, and 

 Castanea chrysophylla * in the same condition ; this evergreen 

 Chestnut forms a shrub three to eight feet high, of a pyramidal 

 shape, with persistent lanceolate leaves, green above, and of a 

 rich golden yellow below. From its situation, and habit in 

 general, it may be expected, if I am fortunate enough to intro- 

 duce it, to withstand the ordinary winters about the neighbour- 



* What was called so formerly is a different species of Castanea.
