description: 2. Aloiampelos Klopper & Gideon F.Sm., gen. nov.   
 Diagnosis: Differs from Aloe L. in the following suite of characters: plants shrubby or climbing; leaves cauline dispersed, sheathing, separated by distinct internodes, unspotted; exudate absent or minimal; inflorescence usually simple; flowers cylindrical to slightly clavate or subventricose, sometimes slightly narrowed above the ovary, but lacking a pronounced constriction above a bulbous basal swelling; perianth segments ± connate.   
 Type: — Aloiampelos ciliaris (Haw.) Klopper & Gideon F.Sm.   
 Aloe series Macrifoliae Haworth (1825: 280). Aloe section Macrifoliae (Haw.) Glen & Hardy (2000: 92). Type:— Aloe ciliaris Haw. [= Aloiampelos ciliaris (Haw.) Klopper & Gideon F.Sm.].   
 Aloe series Striatulae Berger (1905: 47). Type:— Aloe ciliaris Haw. [= Aloiampelos ciliaris (Haw.) Klopper & Gideon F.Sm.].   
 Description:— Shrubby or climbing, herbaceous or sub-woody succulent perennials. Leaves spirally arranged, sheathing, separated by distinct internodes, linear-lanceolate, thin, flat, unspotted, margins dentate to denticulate, apex tapering; exudate absent or minimal, watery, clear to pale yellow, not strong smelling. Inflorescence a simple (seldom 1- or 2-branched) lateral panicle with lax to subdense cylindric, or dense capitate racemes. Pedicels not articulated. Flowers cylindric, slightly trigonous, sometimes subventricose or with a constriction in the middle; segments ± connate; yellow, orange, red or greenish. Stamens and style straight, included or exserted; filaments glabrous. Fruit a loculicidal capsule; seeds numerous.   
 Distribution:— Occurs in South Africa (mainly Western and Eastern Cape), with one species found on the Swaziland border.   
 Etymology: —From Aloe and the Greek word for a climbing plant, ampelos. This refers to the general climbing habit of the scrambling aloes.   
 Chromosome number:— 2n = 14, 4n = 28 and 6n = 42 (Brandham 1971).   
 Chemistry:— Roots usually containing chrysophanol and asphodeline, rarely aloechrysone; 1-methyl-8- hydroxyanthraquinone pathway lacking, hence the absence of aloesaponarin, aloesaponarin II, laccaic acid Dmethyl ester, aloesaponol I, aloesaponol II and isoeleutherol (Van Wyk et al. 1995). Leaf exudate absent or minimal, containing flavonoids as flavones (isovitexin), but lacking dihydroflavonols and flavanones (Viljoen et al. 1998). Included in chemotype A2 (flavones, anthrones and chromones) by Dagne et al. (2000).
