| Abstract: | Lannea alata (Engl.) Engl., Anacardiaceae, a tree or shrub of East Africa, has roots covered with dense wool-like hair. Cork cambium of the root produces a closely appressed cork from which the hairs (modified cork cells) arise. Cork cells and wooly hair are rich in sterol and carotin-oid-like compounds and have thick walls. It is suggested that the root wool plays a role in the soil-air, soil-water relations of Lannea alata and other plants. |
