The Tupelo family (Nyssaceae) are a family of plants within the order of the dogwood-like (Cornales). There is a disjoint area : in North America and in Southeast Asia .
description
Vegetative characteristics
The species of Nyssaceae are always woody plants and usually grow as evergreen trees or bushes .
The alternate leaves arranged on the branches are divided into a petiole and a leaf blade. The simple leaf blade is entire or toothed. Often domatia present. Stipules are missing.
Generative characteristics
The flowers are solitary or in racemose , cephalic or umbellate inflorescences .
The mostly unisexual flowers are usually radial symmetry to sometimes somewhat zygomorphic. There are usually two, rarely three bract circles, each with five bracts, which can all be the same to significantly different. In male and hermaphrodite flowers there are usually two or rarely three circles with usually five stamens each .
Systematics
The Nyssaceae family was established by Antoine-Laurent de Jussieu in Barthélemy Charles Joseph Dumortier . They are closely related to the dogwood family (Cornaceae), to which they are often assigned.
According to Angiosperm Phylogeny Group APG III, the species of the Nyssaceae family were incorporated into the Cornaceae family in a subfamily Nyssoideae Arnott : According to APG IV, however, it is again regarded as a separate family and contains the species of the earlier families Camptothecaceae, Davidiaceae and Mastixiaceae.
In the Nyssaceae family there are two to five genera with 15 to over 30 species:
-
Camptotheca Decne. : It contains only two or three species in China:
- Camptotheca acuminata Decne. : It occurs from Tibet to southern China.
- Camptotheca lowreyana S.Y.Li : It occurs in southern China.
- Camptotheca yunnanensis Dode : It occurs in China in Mengyang, Xishuangbanna and Yunnan. According to WCSP, Camptotheca yunnanensis is a synonym of Camptotheca acuminata .
-
Davidia Baillon , is sometimes run as a separate family Davidiaceae: It contains only one species:
- Handkerchief tree ( Davidia involucrata Baill. ): It occurs in central and southwestern China.
-
Diplopanax Hand.-Mazz. (Some authors also list it together with Mastixia as Mastixiaceae): It contains only two species:
- Diplopanax stachyanthus Hand .-- Mazz. : It occurs from southern China to northern Vietnam.
- Diplopanax vietnamensis Aver. & THNguyên : It occurs in Vietnam.
- Mastixia flower (some authors also list it together with Diplopanax as Mastixiaceae): The 20 or so species are distributed from southern China to tropical Asia.
- Tupelo trees ( Nyssa Gronov. Ex L. , Syn .: Agathisanthes flower , Ceratostachys flower , Daphniphyllopsis Kurz , Streblina Raf. , Tupelo Adans. ): Of the approximately seven species, three are from eastern Canada to the southern USA, one in Central America and three spread from the eastern Himalayas over China to western Malesia.
