1- Introduction to the Subfamily Amaryllidoideae
1.1- Overview The family Amaryllidaceae has threesubfamilies: 1- Subfamily Agapanthoideae- previously the Agapanthaceae family with a single genus. 2- Subfamily Allioideae- previously the Alliaceae family with around 20 genera. 3- Subfamily Amaryllidoideae- previously the Amaryllidaceae family with about sixty genera. Amaryllidoideae is a subfamily of monocotflowering plants in the familyAmaryllidaceae, orderAsparagales. The most recent APG classification, APG III, takes a broad view of the Amaryllidaceae, which then has three subfamilies, one of which is Amaryllidoideae (the old family Amaryllidaceae), and the others are Allioideae (the old family Alliaceae) and Agapanthoideae (the old family Agapanthaceae). The subfamily consists of about sixty genera, with over eight hundred species, and a worldwide distribution. The Amaryllidoideae are herbaceous, perennialflowering plants, usually with bulbs (some are rhizomatous). Their fleshy leaves are arranged in two vertical columns, and their flowers are large.
The subfamily Amaryllidoideae are then further divided into 15 tribes as follows: 2.1- Tribe Amaryllideae + Overview Tribe Amaryllideae Dumortier. is a member of the subfamily Amaryllidoideae in the family Amaryllidaceae. Much of the tribe's generic diversity is confined to South Africa (Snijman and Linder, 1996). A few of the genera extend outside of South Africa proper, but only Crinum, with seeds well suited to oceanic dispersal (Koshimizu, 1930), ranges through Asia, Australia, and America.
+ Subtribes and Genera Snijman and Linder's (1996)phylogenetic analysis of the tribe based on morphological, floral and seed anatomical, and cytological data resulted in recognition of two monophyletic subtribes: 1- Subtribe Crininae: Genera: 1- Ammocharis, 2- Boophone, 3- Crinum, 4- Cybistetes 2- Subtribe Amaryllidinae: Genera: 1- Amaryllis, 2- Nerine, 3- Brunsvigia, 4- Crossyne, 5- Hessea, 6- Strumaria, and 7- Carpolyza).
