What kind of begonias are there?
With the aim of clarifying their systematic position and generic circumscription, morphological and anatomical studies were carried out on 18 species of Alstroemeria and 11 species of Bomarea. Light microscopy (LM) and scanning (SEM) and transmission (TEM) electron microscopy were used to study the morphology of mature seeds and pollen. Observations on the most distinctive characters are discussed and compared with other data available for Alstroemeriaceae.
Morphology of subterranean organs, pollen exine, adaptive dehiscence of capsules, seed dispersal, seed coat and karyotype characteristics (such as basic chromosome number and symmetry) support the view that these genera are related but should have independent generic status. Results indicate that Alstroemeriaceae comprises three genera: Alstroemeria (including Schickendantzia and Taltalia), Bomarea and Leontochir.

Leaves evenly dispersed on an elongated stem or crowded at its upper end, or on short stems as a rosette near to the ground. Leaves simple, entire, parallel- or arched-veined, thin or somewhat fleshy, generally twisted at the base and leaf blade becoming half or totally inverted (resupinate) (except Bomarea subgen.
Wichurea, some Alstroemeria and Schickendantzia spp. ), in the flowering stems of Alstroemeria often reduced to sessile bracts. Inflorescence terminal, 2- to manyflowered, lax or dense, bracteate, umbel-like, simple or branched, or flowers solitary.
Bracts leaflike or reduced, at the base of the inflorescence a pseudowhorl of bracts. Flowers bisexual, actinomorphic or zygomorphic, epigynous. Tepals 3 + 3, petaloid, free, the 2 whorls similar or conspicuously different, the inner ones often basally narrowed into a canaliculate, nectariferous claw.
Stamens 3 + 3, free, anthers pseudobasifixed, ± sagittate, dithecal, tetrasporangiate, latrorse, opening by 2 longitudinal slits; filaments filiform, erect or curved. Ovary inferior, turbinate, syncarpous, 3-carpellate, unilocular with parietal placentae ( Leontochir, Schickendantzia) or trilocular with axile placentae (other genera); septal sectaries absent; style filiform, at the base triangled, apically with 3 stigmatic branches. Tepals, stamens and style caducous, except in Leontochir.
Ovules usually many, in 2 rows, anatropous, bitegmic, tenuinucellate. Fruit a usually dehiscent, dry, leathery, or somewhat fleshy capsule, loculicidal, 3-valved, in Alstroemeria mostly explosive, rarely fruit berrylike and indehiscent. Seeds ± globose, brown, with or without a red sarcotesta.
