Comparative anatomical and histochemical studies were made on some physiological species of hemp (Cannabis sativa L.), as shown in Table I. On the other hand, spodograms of hemp and tobacco leaves (Fig. 5) were examined, and the result obtained was follows : 1) Foliage leaves, bracts on inflorescence of female plant, and bractlets on each flower of material No. (1) (Minami-oshihara No. 1), which is typically cultivated in Japan, were examined. Four types of hair, such as bristle, glandular, disk-shaped glandular, and downy hair, are characteristic, especially the disk-shaped glandular hair of type-2 and 3 have very peculiar shape and other features (Table II, Fig. 1). Examination was also made for histochemical color reactions of the organs including oleo-resin (Table III). 2) Internal characters of material No. (2) (wild species from Hokkaido area), No. (4) (wild sp. from Kyusyu area), and No. (5) (American cannabis) are practically similar to No. (1), but those of material No. (3) (wild sp. from Kanto area) and No. (6) (Ganjah) are different. 3) It was confirmed that even if the materials of Cannabis sativa L. are burnt to ash, it is easy to discriminate them from tobacco leaves by the presence of bristle hairs and also rosette aggregates of calicium oxalate in the former spodogram (Fig. 5, 1∼5).
