Rhododendron

By the aid of the processes described Tunmann claims to have discovered the resinogenous layer in all the plants examined by him. In the course of his investigations he was able to determine various typical forms of the layer. These he divides into three principal types the rod-type (Viola Fraxinus, Alnus), the vacuola-type (Salvia.Hyssopus), and the mesh or grille-type (Rhododendron, Azalea).

Ironically, coffee does need relatively acidic soil, with pH between 5 and 6. Conifers and shmbs such as azaleas and rhododendrons thrive on soils with this acidity, as do tea, potatoes, rice, and rye. The vast majority of crop plants, including most vegetables, need soils just on the acidic side of neutral, pH between 6 and 7. Only a few crops—barley, sugar beets, cotton, and sugarcane—like soils on the mildly basic side, between pH 7 and 8, and only desert plants can cope with soils whose pH is greater than 8.

As the 21st century progresses, the bulk of e-mails will be meaningless. Already, many subject lines convey no meaning at all in order to avoid and trick spam filters that are designed to eliminate traditional spam. Thus, crazy, unpredictable subject lines like visual, rhododendron, purveyor, noodle are becoming common, although I wonder how many people really open these mails. If you do open them, the mails get even harder to decipher, and we see ...
