Styles are lessnumerous than in the latter, and are distinguished by their shorterlength, absence of hairs and the smoothness of the epidermal cooked products it is not usually evident that the styles arisefrom a depression in the drupelet. The seeds are larger than in theraspberries, but in histological structure are very similar. Theyare, however, distinguished from the latter by the thicker innerendocarp and by the fact that the cells of the outer epidermis of the. Fig. 14.—Blackberry style and stigma. X 32. spermoderm are about half the diameter of those of the innerepidermis; whereas, in the raspberry the reverse is true. In black-berry preserves, unlike that made from raspberries, hairs are few orentirely absent; but tissues of the receptacle, notably the vascularelements, are present. Compared with the strawberry, the bundles are shorter, but morestrongly developed, with larger and more numerous vessels. Elon-gated epidermal cells and crystal clusters are also distinguishable. THE RED CURRANT (Ribes rubrum L.). Both the red and white garden varieties of currant are derivedfrom the European species, R. rubruni. Three varieties, grown inthe Experiment Station garden, have been examined by the writer;Fays Prolific, a red variety with berries often 1-25 centimeters indiameter, Versaillaise, a smaller berried red variety, and the whitegrape. All of these have the same microscopic structure. Macroscopic Structure.
