The alternate arranged leaves are divided into petiole and leaf blade. The above grooved petiole is 10 to 15 mm long. The simple, almost leathery leaf blade ovate - elliptical with a length of 8 to 13 cm and a width of 4 to 8 cm. Is pinnately with 8 to 13 lateral nerves on either side of the main nerve. The leaf margin is doubly serrate. The lower leaf surface is hairy at first woolly, later varying degrees covered with simple trichomes. The upper leaf surface is bare. The approximately 15 mm long stipules include the branch and early fall from where they leave a distinct leaf scar.

Inflorescences and flowers

Ticodendron incognitum is dioecious getrenntgeschlechtig ( diöziosch ) or polygamodiözisch. The inflorescences are simple or compound, hanging, 1.5 to 4 cm long kitten with bracts. One to three male flowers are close together and form a composite kitten. Female flowers appear singly in simple kitten. The unisexual flowers are small and reduced. Bracts are rudimentary in female flowers; in male flowers they are missing. In the male flowers eight to ten free, fertile stamens with 2 to 3 mm long stamens and with a length of about 2 mm oblong anthers are present. The female flowers are each about three ephemeral cover sheets. Two carpels to a inferior ovary grown. The two, rarely three free pen have long scars. Pollination is about the wind ( anemophily ).

Fruits

Those with a length of about 7 cm and a diameter of about 4 cm of asymmetric stone fruit is somewhat fleshy and contains a seed. The longitudinally ridged endocarp is very hard.

Occurrence

The distribution is purely neotropisch: from central Mexico to Guatemala, Costa Rica, Nicaragua, Honduras to southern Panama. Ticodendron incognitum thrives in the evergreen mountain cloud forest. It grows best at altitudes between 900 and 2300 meters. This species is found only in small populations or as single copies.

Trivial names in the home areas are " Jaúl macho ", " Jaúl nazareno ", " Duraznillo " or " candelillo morado ".

System

The genus Ticodendron 1989, f 1-6 erected incognitum by Jorge Gómez and Luis Diego Gómez Laurito in Annals of the Missouri Botanical Garden, 76 (4 ), pp. 1148-1151 with the first description of the species Ticodendron. The Ticodendraceae family was only in 1991, set up by Jorge Gómez and Luis Diego Gómez Laurito in Annals of the Missouri Botanical Garden, 78 ( 1), p 87. This species is most closely related to the Betulaceae.

Ticodendron derived from Tico, which in Costa Rica is a diminutive and dendron, the Greek word for tree, so directly translated would be the " tree ".

In the family Ticodendraceae Gómez -Laur. & LDGómez there is only one monotypic genus:

• Ticodendron Gómez -Laur. & L.D.Gómez with the only kind: Ticodendron incognitum Gómez -Laur. & L.D.Gómez
