Blommetaks-familien ( Danish )

provided by wikipedia DA

Blommetaks-familien (Cephalotaxaceae) er en lille familie med tre slægter, der står Taks-familien nær. Den olivenagtige (eller altså: blommeagtige) frugt modner dog først efter to år.

Cephalotaxaceae

Cephalotaxus harringtonii

Cephalotaxaceae is a small grouping of conifers, that included one to three genera closely allied to Taxaceae. However, members of Cephalotaxaceae are now included in Taxaceae by botanists, instead of as a distinct family, based on phylogenetic evidence and close morphological similarities between them.[1][2][3][4][5] Included species were restricted to east Asia, except for two species of Torreya found in the southwest and southeast of the United States; fossil evidence shows a much wider prehistorical Northern Hemisphere distribution. The most notable differences between Taxaceae and Cephalotaxaceae concerned the cone aril, which fully encloses the seeds of Cephalotaxaceae, the longer maturation of Cephalotaxaceae seeds and the larger size of the mature seeds.

When considered as a distinct family, members of Cephalotaxaceae are much branched, small trees and shrubs. The leaves are evergreen, spirally arranged, often twisted at the base to appear biranked. They are linear to lanceolate, and have pale green or white stomatal bands on the undersides. The plants are monoecious, subdioecious, or dioecious. The male cones are 4–25 mm long, and shed pollen in the early spring. The female cones are reduced, with one to a few ovuliferous scales, and one seed on each ovuliferous scale. As the seed matures, the ovuliferous scale develops into a fleshy aril fully enclosing the seed. The mature aril is thin, green, purple or red, soft and resinous. Each ovuliferous scale remains discrete, so the cone develops into a short stem with one to a few berry-like seeds. They are probably eaten by birds or other animals which then disperse the hard seed undamaged in their droppings, but seed dispersal mechanisms in the family are not yet well researched.

Cephalotaxaceae ( Spanish; Castilian )

provided by wikipedia ES

Cephalotaxaceae, son una familia del Orden Pinales. Esta pequeña familia de coníferas, con alrededor de 20 especies, se encuentra relacionada con la familia Taxaceae, e incluidas en esa familia por algunos botánicos. Están restringidas al este de Asia, excepto en lo que se refiere a dos especies de Torreya que se encuentran en el suroeste y sudeste de los Estados Unidos; la evidencia fósil muestra una distribución mucho más amplia en el Hemisferio norte prehistórico. Las diferencias entre las dos familias son las siguientes:

* Hasta 25 mm en Austrotaxus

Se trata de arbustos o pequeños árboles con muchas ramas. Las hojas son perennes, dispuestas en espiral, a menudo retorcidas en la base para aparecer en dos filas. Son lineales a lanceoladas, y tienen bandas estomatales de color verde claro o blancas por el envés. Las plantas son monoicas, subdioicas o dioicas. Los estróbilos masculinos tienen 4-25 mm de largo, y lanzan el polen a principios de la primavera. Los conos femeninos son reducidos, con una a unas pocas escamas ovulíferas, y una semilla en cada escama ovulífera. Conforme la semilla madura, la escama ovulífera se desarrolla en un arilo carnoso que rodea por completo a la semilla. El arilo maduro es delgado, verde, púrpura o rojo, suave y resinoso. Cada escama ovulífera permanece discreto, de manera que el cono se desarrolla como una rama corta con una a varias semillas de bayas. Son probablemente comidas por las aves y otros animales que luego dispersan la semilla dura sin lesionar en sus deposiciones, pero los mecanismos de dispersión de semillas en la familia no están todavía bien investigados.

Peajugapuulised ( Estonian )

provided by wikipedia ET

Peajugapuulised (Cephalotaxaceae) on igihaljaste okaspuude sugukond okaspuulaadsete seltsist.

Peajugapuuliste sugukonda kuulub kolm perekonda ja umbes 20 liiki. Mõnikord arvatakse peajugapuulised jugapuuliste sugukonda.

Sugukonda kuuluvad tugevalt hargnevad väikesekasvulised puud ja põõsad, mis kasvavad valdavalt Ida-Aasias; üksnes kaht pähkeljugapuu liiki on leitud ka Põhja-Ameerikast.
