Indumentum

All species are subglabrous and possess small, sericeous or puberulous simple hairs only, which can be seen with high magnification only. These hairs occur on all young plant parts and are often early caducuous, which makes the plants seemingly glabrous with the exception of A. ovalis (Ridl.) Gage , A. subsessilis and A. trichogyna Airy Shaw , which often have a more dense covering. Places where hairs are more persistent are the branch tips, sepals, sometimes on or near brachyblasts or in the axils of leaves. In most species indumentum is occasion- ally found on the abaxial leaf blade with more hairs towards the blade base. If present, hairs on the main veins are mostly persistent.
