Aesculus pavia

Red Buckeye (Aesculus pavia )

The Real Pavie or Red Buckeye (Aesculus pavia ) is a native North American representative of the horse chestnut (Aesculus ).

Features

The Real Pavie is a shrub or tree 1-4, rarely to 12 m Height. The trunk diameter is 20, rarely up to 50 cm. The bark is brown -gray to light gray and smooth. The branches are reddish brown. The buds are trimmed, broadly ovate, an inch long and have around - pointed scales.

The leaves consist of 5 or 7 palmately arranged leaflets. The petiole is 3-17 cm long, glabrous or hairy. The leaves are 6-17 cm long, 3-6 cm wide, oblong, ovate, narrowly elliptic, lanceolate or verkehrtlanzettlich. You are membranous to slightly leathery, nerves are sunk deep at the top. The blade end is tapered acuminate until suddenly, the leaf base is tapered or pointed. The leaf margin is irregularly cut or notched - sawn, entire at the base of the leaf. The top is bald with scattered hairs on the main veins, the underside is bare hairy to dense, dull to shiny dark green with reddish center and side fins. The sub-petioles are 1-19 mm long.

The inflorescence is elongated and 10 to 25 cm long. The flowers are red, often yellowish- red, also pure yellow at the westernmost populations in Central Texas. The nails of the petals are yellow and maroon in the heyday. The flower stalk is 5-12 mm long, usually very slender, short haired and drüsenlos. The calyx is 8-18 mm long, tubular and bell-shaped or Roehrig, shaggy hairy with scattered stalked glands. The five sepals are rounded, glandular - hairy and unequal in size. The crown is glandular - pubescent, the margin glandular. The upper petals are 25-40 mm long, the nail 19 to 23 mm and shaggy, the nail small, oblong- ovate to almost circular. The lateral petals are 20-31 mm long, the nail 10 to 17 mm that is about the same length as the calyx, and shaggy; the plate is oblong- ovate. The 6 to 8 stamens are 23 to 36 mm long, the stamens are hairy shaggy on the bottom half. The anthers are smooth with few hairs at base and apex, very sparsely glandular at the tip and base of the loculi. The stamps are shaggy with the exception of the scar, the pen is the same length as the stamens or protrudes 2-4 mm above the upper petals.

The capsule fruit is approximately spherical to egg-shaped and has a diameter of 3.5 to 6 cm. The pericarp is smooth, light pitting and light brown. The 1-3, rarely 4-6 seeds 2 to 3 cm in diameter, are dark chestnut brown to light yellow-brown and have a bright navel.

Dissemination and locations

The Real Pavie is mainly due to the coastal plains on the Atlantic and Gulf of Mexico from North Carolina south to Florida, west to the Balcones Escarpment in south-central Texas ( Uvalde and Edwards County) ago. In the north of the area to Arkansas, West Tennessee enough in alluvium of the Mississippi to Southeast Missouri and Southern Illinois.

It grows in pine forests, pine - deciduous mixed forests, oak - hickory forests and clearings. Most commonly it grows along river banks, on current benches on -drained soil, but also grows well on shallow, poorly drained Schwemmflächen of rivers and streams, also on the edge of swamps and marshes. It is locally common and is in the territory of the dominant understory shrubs.

System

The Real Pavie is placed in the section within the genus Aesculus Pavia. She is a very variable species and has been divided in the past in several ways. In the absence of discontinuities in the variability of this species were discarded. A part of the variability is due to the introgression of other species of the section, such as the yellow color on the crown introgression of Aesculus sylvatica and Aesculus glabra.

The Real Pavie is a parent species often planted as ornamental tree in Central Europe hybrids meat Red Horse Chestnut ( Aesculus × carnea).
