Crataegus laevigata

Monday, May 24th, 2010

Crataegus laevigata, known as the midland hawthorn, woodland hawthorn or mayflower, is a species of hawthorn native to western and central Europe, from Great Britain (where it is uncommon, and largely confined to the Midlands) and Spain east to the Czech Republic and Hungary.

It is a large shrub or small tree growing to 8 m (rarely to 12 m) tall, with a dense crown. The leaves are 2–6 cm long and 2–5 cm broad, with 2–3 shallow, forward-pointing lobes on each side of the leaf. The hermaphrodite flowers are produced in corymbs of 6–12, each flower with five white or pale pink petals and two or three styles, and are pollinated by midges. The fruit is a dark red pome 6–10 mm diameter, slightly broader than long, containing 2–3 nutlets.

It is distinguished from the related Common Hawthorn, C. monogyna, in the leaves being only shallowly lobed, with forward-pointing lobes, and in the flowers having more than one styles. However hybrids occur frequently.

Datura ceratocaula

Monday, May 24th, 2010

Datura ceratocaula is a species of Datura. It is weed-like in its natural habitat, but is grown in gardens and yards as an ornamental plant. The flower has a sweet smell. It is an annual plant that originally came from Mexico.

In its natural habitat Datura ceratocaula grows in shallow water or in a swamp. It has a hollow gray-green stalk between 12 and 36 in. long, with toothed, undulated ovate-lanceolate leaves that have hairs on the underside.

The plant’s broad, funnel-shaped flowers bloom from June to September. They are white with a blue cast on the outside and white to pink on the inside. The seed pods are not thorny like those of most Datura species, instead having the appearance of inverted eggs as they dangle from the plant. The plant’s stalks are curved like an animal’s horn (ceratocaulus = curved like a horn), and have less tendency to fork than other species of Datura.

All parts of Datura plants contain dangerous levels of poison and may be fatal if ingested by humans or other animals, including livestock and pets. In some places it is prohibited to buy, sell or cultivate Datura plants.

Datura ceratocaula’s toxicity is such that it can be transmitted up the food chain. A species of duck lives in the swamps and lagoons near Mazatlán. Their meat is said to be poisonous, and eating it has been known to produce symptoms of having been poisoned or drugged. This was long a mystery, but now it is known to be due to Datura poisoning. The ducks eat the leaves and seeds of Datura ceratocaula, and their flesh contains a toxic level of poison from this diet.

Desert Thorn-apple

Monday, May 24th, 2010

Datura discolor, also called the desert thorn-apple, is an herbaceous annual plant native to the Sonoran Desert of western North America, where it grows in sandy soils and washes. All parts of the plant contain a mix of alkaloids that are potentially lethal when enough is ingested. Deaths from careless recreational use of Daturas and related plants are frequently reported.

The species was first described in 1833. The term discolor, meaning “various colors,” refers to its upward-growing trumpet-shaped flowers, which are white in the bell, and pale to dark violet from the narrow part of the bell to the base. The plant itself is an upright or low-lying shrub that can grow to 4 1/2 feet tall. Its foliage is light green, and its stalks have conspicuous purple stripes. The ovate-shaped leaves can be whole or toothed..

Datura discolor has the largest flowers (up to 6 1/2 in. in diameter) of any Datura species, which makes it attractive for garden cultivation. The flowers open for only one night and wither the following day. Its seed capsule is thorny like most other Daturas, and can be up to 3 in. long and 2 1/2 in. in diameter. The species’ natural distribution area stretches from Mexico to the Southwestern U.S. and the Caribbean Islands. It is a sun-loving plant which does well underneath overhanging eaves that can protect its flowers from damage by rainfall.
