Vegetative characteristics
Alloplectus species grow as epiphytic subshrubs . The mostly climbing stems have a round to square cross-section.
The opposite arranged leaves are divided into a petiole and a leaf blade. The simple leaf blades are elliptical to ovate with smooth or serrated edges.
Generative characteristics
The flowers are individually in the leaf axils up to three together in zymous inflorescences. There are cover sheets.
The hermaphrodite flowers are five-fold and zygomorphic with a double flower envelope . The five almost free, hairy sepals are green to colored with a smooth to serrate edge. The five yellow or red petals are fused tubular or plate-shaped. The four stamens are more or less connected. The nectar gland is usually bilobed. The upper ovary is hairy.
The two-lobed, fleshy capsule fruits are surrounded by the calyx and contain many tiny seeds.
Locations
The Alloplectus species grow at altitudes of (rarely 500 to) mostly 2000 to 3500 meters.
Systematics and distribution
The genus Alloplectus was established by Carl Friedrich Philipp von Martius .
For a long time, alloplectus was a collecting pot of not closely related species, so it was not monophyletic . According to the revision by JL Clark (Clark 2005, 2006 and Clark et al. 2006), the genus Alloplectus s. st. only five species left. The other of the previously around 140 species are now classified, for example, in the genera Crantzia , Glossoloma and Drymonia .
The Alloplectus species are distributed from Costa Rica to the Colombian Andes , in northern Ecuador and Peru .
- Alloplectus aquatilis C.V.Morton : It occurs in Colombia in the province of Cundinamarca and in Venezuela in the provinces of Mérida and Táchira .
- Alloplectus hispidus (Kunth) Mart. ( Syn . : Besleria hispida Kunth , Columnea humboldtiana Kuntze ): It occurs in Colombia in the departments of Antioquia , Cauca , Chocó , Cundinamarca, El Valle , Huila , Magdalena , Meta , Nariño , Quindío , Risaralda , Tolima and Valle del Cauca , in Ecuador in the provinces of Azuay , Loja , Napo , Tunguragua , Tungurahua , Zamora , in Peru in the province of Piura and in Venezuela in the provinces of Aragua , Falcon , Táchira and Yaracuy .
- Alloplectus inflatus J.L.Clark & LESkog : It occurs in Colombia in the departments [Boyacá], Caldas , Cauca, Cundinamarca, Meta and Tolima.
- Alloplectus tessmannii Mansf. : It occurs in Peru in the provinces of Amazonas , Huánuco , Loreto and San Martín .
- Alloplectus weirii (Kuntze) Wiehler (Syn .: Columnea weirii Kuntze , Alloplectus lindenii (Kuntze) Wiehler nom. Illeg., Columnea lindenii Kuntze nom. Illeg. Non Brongn. Ex Lem. , Columnea schlimii Kuntze nom. Nud. Pro syn. Non (Planch.) Kuntze , Crantzia lindenii (Kuntze) Fritsch nom. Illeg., Crantzia weirii (Kuntze) Fritsch ): It comes in Costa Rica , in Bolivia in the province of La Paz , in Colombia in the departments Antioquia, Boyaca , Boyacá , Caldas, Caquetá , Cundinamarca, Quindío , Santander , Tolima and Valle del Cauca, in Ecuador in the provinces: Morona-Santiago , Napo, Pastaza , Tungurahua and Zamora-Chinchipe and in Peru in the provinces of Cajamarca, Cuzco , Loreto and San Martín .
Presumably none of the five species from this genus is (to a new extent) in culture (Clark 2006).
