Taxus baccata L. Taxaceae European Yew. Trees are feminine in Latin, so while Taxus has a masculine ending (-us), its specific name, baccata (meaning 'having fleshy berries' (Stearn, 1994)), agrees with it in gender by having a female ending ( -a). Distribution: Europe. Although regarded as poisonous since Theophrastus, Gerard and his school friends used to eat the red berries (they are technically called 'arils') without harm. Johnson clearly ate the fleshy arils and spat out the seed, which is as poisonous as the leaves. It is a source of taxol, an important chemotherapeutic agent for breast and other cancers. It was first extracted from the bark of T. brevifolia, the Pacific yew tree, in 1966. About 1,100 kg of bark produces 10 g of taxol, and 360,000 trees a year would have been required for the needs of the USA – an unsustainable amount. In 1990 a precursor of taxol was extracted from the needles of the European yew so saving the Pacific trees. It is now produced in fermentation tanks from cell cultures of Taxus. Curiously, there is a fungus, Nodulisporium sylviforme, which lives on the yew tree, that also produces taxol. Because taxol stops cell division, it is also used in the stents that are inserted to keep coronary arteries open. Here it inhibits – in a different way, but like anti-fouling paint on the bottom of ships – the overgrowth of endothelial cells that would otherwise eventually block the tube. The economic costs of anticancer drugs are significant. Paclitaxel ‘Taxol’ for breast cancer costs (2012) £246 every 3 weeks

Nepal; agriculture in the Khumbu, 1986. Pangboche (altitude 4200 metres), showing the tiny, walled terraced fields on which Sherpas cultivate their staple crops (potatoes, barley, wheat). Potatoes are rarely grown beyond 4000 metres but barley is grown at higher altitudes. Scattered juniper and birch trees share this terrain with sub-alpine grasses. Few people live permanently beyond this village amid the last scattered trees below the treeline.

Krsna enchants the natural and human worlds with his flute. Standing in the tribhangi or 'three bends' posture, Krsna plays the flute as enchanted gopis, cattle, and birds look on. A clump of trees act as a sheltering umbrella, the symbol of gods and kings in Indic iconography.
