durioneae造句

• "' Durioneae "'is a tribe within the subfamily Helicteroideae of the plant family Malvaceae s . l.
• Durioneae has traditionally been placed within the Bombacaceae because of the combination of monothecate anthers, smooth pollen, and tree habit.
• The most recent molecular evidence ( on which the most recent, well-supported circumscription of Durioneae is based ) therefore refutes Corner's Durian Theory.
• In this circumscritpion of Malvaceae, the family is divided into 9 subfamilies and Durioneae is placed into the subfamily Helicteroideae, along with some of the members of the traditional Helictereae.
• The authors of these studies hypothesize that monothecate anthers have most likely evolved convergently in Durioneae and in the Malvatheca clade ( comprising Malvaceae s . l . subfamilies Malvoideae and Bombacoideae ).
• However, in more recent circumscriptions of Durioneae, the tribe into which " Durio " and its sister taxa fall, fleshy arils and spiny fruits are derived within the clade.
• Durio is often included in Bombacaceae because of the presence of monothecate anthers, as opposed to the bithecate anthers common to the rest of the tribe Durioneae should actually be placed in the subfamily Helicteroideae of an expanded Malvaceae.
• Some scientists have hypothesized that the development of monothecate anthers and larger flowers ( compared to those of the remaining genera in Durioneae ) in the clade consisting of " Durio, Boschia ", and " Cullenia " was in conjunction with a transition from beetle pollination to vertebrate pollination.
