Description
Appearance and leaf
The funnel - or Zisternenbromelie Hohenbergiopsis guatemalensis grows as a perennial herbaceous plant epiphytic. It is a relatively large species with funnel diameters up to 1 meter, which reached inflorescence growth heights of 0.7 to 1 meter. In the leaf hoppers often collect large amounts of water.
The tough, parallel venation, wide - lineal, usually up to 60 cm long, green or red leaves have a sharp serrated leaf edge (ie, like almost all kinds of Bromelioideae armored) and end in an approximately 1 cm long spike tip. Saugschuppen are located both on the leaf surface as underside.
Inflorescence, flower and fruit
In relation to Hohenbergia types of inflorescence towers over the leaf hopper little. The thick, woolly hairy inflorescence stem is shorter than the rosette leaves. The imbricate on the inflorescence stem overlapping bracts ( bracts ) are pointed broadly elliptical and pungent. The handsome, relatively short -lasting, almost club-shaped, cylindrical, about 20 cm long inflorescence ( inflorescence ) is composed of tight peg-shaped, ellipsoidal, aged men part inflorescences and contains many flowers. The approximately 18 cm long bracts are acuminate. There are no flower stems available.
The radial symmetry, the threefold flowers have a length of about 1 cm. The three oval with a length of 4 to 8 mm sepals are fused into a short tube and tapered end. The three purple petals are above the ovary free. The petals have at their base, in contrast to the genus Hohenbergia and most species of the subfamily of Bromelioideae no scales ( ligule ). There are two circles, each with three stamens present. The stamens are fused into a tube, this is an exception within the family. The pollen grains are combined into a tetrad; at Hohenbergia the pollen grains are individually. The ovary is inferior.
The flowers formula is:
Are formed berries.
Dissemination
The home of Hohenbergiopsis guatemalensis ranges from southern Mexico to Guatemala. It thrives in the cloud forest at altitudes 800-2000 m. She was a long time only from the type location Tactic, known on the road to Tamaha in Alta Verapaz in Guatemala, where in 1997 grew about 30 plants.
System
This type was introduced in 1941 under the name Hohenbergia guatemalensis by Lyman Bradford Smith in Lilloa, 6, pp. 282 firstdescribed. The highly divergent from the other species of the genus Hohenbergia features made it necessary to outsource this kind handled and with Hohenbergiopsis guatemalensis a new genus Hohenbergiopsis. This was done by Lyman Bradford Smith and Robert William Read in Phytologia, 33 (7 ), 1976, pp. 440 The genus name refers to the genus Hohenbergiopsis Hohenbergia. The specific epithet guatemalensis refers to the long time single locality of its kind in Guatemala.
