Mycorrhizae in Taxus baccata and Pinus wallichiana

The mycorrhizae of yew (Taxus buccuta) and blue pine (Pinus wallichiana) are described. The former is typically endotrophic and the latter ectotrophic. The ischolar_main systems and the mycorrhizae in blue pine (Pinus wullichiuna) and in yew (Tuxus baccata) were studied from plants growing in natural habitat in the temperate Himalayas (alt. 7,000-10,000 ft.) in Upper Bashahr division, Himachal Pradesh State. Chaudhuri (1945) mentioned the presence of endotrophic mycorrhizae in T. buccuta but no details of the ischolar_main system and the fungal infection in the ischolar_mains were given. Anvery and Khan (1959) have recorded mycorrhizae on blue pine but give no details.
