14_30 Kew, England Rolfe, R. A., the orchid man, speaks of a genus of orchids which is a hybrid genus - a wild genus of natural hybrids! - Laelio - cattleya. He, also, showed me the other day what appeared to be round galls on a specimen of Amelanchier utahensis Koehne (?= A. alnifolia var.) but which were fruits affected by a fungus, Sphaeria Collinsii, Schweinitz. Very curious with tubular processes all over it. - Rolfe walks in a very erect mannner, thus, some people in Kew nickname him "Poker-back". - Rhamnus Purshiana and Californica. Went into the City today and saw Perredes. He had some interesting things to say about the above species. He planted the seeds and found that Purshiana kept its leaves the first two years! Also found that minor forms of Rhamnus |
14_31 Nov. 22, 1905. Californica (sand hill forms, depressed and twiggy as against forms of other places where the conditions are better) kept their characters in cult. - [therefore] these forms are constant. I pointed out that forms of Purshiana in the North Coast Ranges well south say in Mendocino and Sonoma are evergreen to which Perredes agreed. He admitted that there were forms which suggested gradual shading of one species into the other. True Purshiana he found on Big River Mendocino Co and no further southward. R. tomentalla, seedlings, show no tomentum on leaves first tow years or scarcely any! - Pringle, C. G. Coll. at Lakeport, Aug. 1882 |
