Telfairia ( German )

provided by wikipedia DE

Telfairia ist eine Pflanzengattung innerhalb der Familie der Kürbisgewächse (Cucurbitaceae). Die nur drei Arten kommen im tropischen Afrika vor. Zwei Arten werden regional als Nahrungspflanzen angebaut.

Beschreibung

Illustration von Telfairia occidentalis

Vegetative Merkmale

Telfairia-Arten wachsen als Lianen, die bis zur 30 Meter lang werden können. Sie besitzen drei- bis siebenfach fußförmig geteilte Blätter und zweiteilige Ranken.

Generative Merkmale

Telfairia-Arten sind zweihäusig getrenntgeschlechtig (diözisch). Vorblätter fehlen. Die Blüten sind relativ groß und purpurfarben.

Viele männlichen Blüten stehen in einem traubigen Blütenstand zusammen. Die Blütenröhre ist kurz und breit, die Kelchlappen gezähnt. Die fünf Kronblätter sind frei und mit langen Fäden ausgefranst. Sie besitzen fünf oder drei Staubblätter. Bei fünf sind alle bithekisch; bei drei besitzen zwei Staubblätter vier Theken und eines zwei Theken. Die Staubblätter sind nicht verbunden und setzen an der Blütenröhre an. Die Theken sind gerade oder leicht gebogen.

Die weiblichen Blüten stehen einzeln. Ihre Blütenhülle gleicht den männlichen. Der Fruchtknoten ist gerippt. Die zahlreichen Samenanlagen stehen horizontal. Die Narbe ist dreilappig.

Die relativ große, fleischige, gerippte Frucht öffnet sich mit zehn längsverlaufenden Klappen und enthält viele Samen. Die Samen sind relativ groß, breit-oval bis fast rund im Umriss, und flach. Sie sind in eine faserige Endokarp-Hülle gebettet.

Systematik

Die Gattung Telfairia wurde 1827 durch William Jackson Hooker in Botanical Magazine, 54, Tafel 2751–2752 aufgestellt. Der Gattungsname Telfairia ehrt den irischen Arzt und Botaniker Charles Telfair (1778–1833).[1]

Bei C. Jeffrey 2005 und Kocyan et al. 2007 wird die Gattung Telfairia zur Tribus Joliffieae in der Unterfamilie Cucurbitoideae innerhalb der Familie Cucurbitaceae gestellt. In der auf morphologischen Merkmalen basierenden Systematik von C. Jeffrey 2005 bildet die Gattung Telfairia zusammen mit Odosicyos die Subtribus Telfairiinae. Bei Kocyan et al. 2007 zeigen DNA-Sequenz-Analysen die Gattung Telfairia innerhalb der paraphyletischen Tribus Joliffeae als Schwestertaxon der Klade (Ampelosicyos + Tricyclandra + Odosicyos).[2]

In die Gattung werden drei Arten gestellt:

Mkweme ( Swahili )

provided by wikipedia emerging languages

Mikweme ni mimea ya jenasi Telfairia katika familia Cucurbitaceae. Ina umbo la kamba na kutambaa juu ya miti yenye shina kubwa. Matawi yake yanafikia urefu wa mita 30.

Matunda yake ni makubwa sana; yale ya mkweme mashariki yanaweza kufikia kg 15. Mbegu huitwa kweme na hutumika kama chakula na kwa kutengeneza mafuta. 25% ni protini na 55% ni mafuta, hivyo zinafaa sana kama chakula bora, kwa mfano kwa akina mama baada ya kujifungua.

Asili yake ni Afrika.

Telfairia

provided by wikipedia EN

Telfairia is a small genus of flowering plants in the squash family which are native to Africa. They include Telfairia occidentalis, the fluted pumpkin, which is an important vegetable in Nigeria and other African nations. It is also known as the oyster nut, a common name it shares with its relative Telfairia pedata. These are woody and herbaceous dioecious vines which bear squashlike fruits that contain large, nutritious oily seeds. The third species is Telfairia batesii which is very rare and not cultivated.

These vines grow quickly to lengths of 30 meters or more, using tendrils to scale trees. T. pedata is grown as an ornamental plant for its attractive foliage. The seeds of T. occidentalis and T. pedata are over 25% protein and 55% oil, making them a good source of nutrition. They are used as a traditional food source for nursing mothers; the seed flour is fermented to make baby food; and the leaves and shoots, especially of T. occidentalis, are eaten as vegetables.[1]

One recent concern has been the impact of telfairia mosaic virus, which, along with other problems, is a threat to the already low genetic diversity of plants of this genus.

Species:

The genus was named for Irish naturalist Charles Telfair (1778–1833).
