Morphology General

Annual herb, erect, procumbent, trailing or straggling up to 2 m in height, sometimes using associated vegetation for support; branches spreading or ascending, stems fleshy or herbaceous, light to dark green; all parts viscid-pubescent with eglandular and glandular hairs, denser on young vegetative and floral stems

Morphology Reproductive morphology Inflorescences

Inflorescences leaf-opposed to extra-axillary racemose simple or forked cymes, usually 5–12-flowered; flowers pendent, usually 5partite but often 6–10-partite in cultivars; peduncles 0.5–3.5 cm long in flower, 2–4.8 cm long in fruit; pedicels 4–15 mm long in flower, 1–1.6 cm long in fruit, articulated at or above the middle from where deflexed in flower and in fruit; axes pubescent with short appressed and long spreading glandular-headed hairs

Morphology Reproductive morphology Flowers Calyx

Calyx campanulate/stellate, divided almost to base, 3.5–11 mm long, densely pubescent externally; lobes narrowly triangular to lanceolate, 3–9 × 0.7–2 mm, acute, strongly reflexed in fruit when 7–14 × 1.5–2.8 mm

Morphology Reproductive morphology Flowers Corolla

Corolla yellow, with greenish basal star, stellate, 1.4–2.4 cm diameter, tube 0.5–1.3 mm long; lobes narrowly triangular to lanceolate, 5–9 × 1.3–3(–4) mm, glandular-pubescent externally, glabrous internally, strongly reflexed exposing androecium after anthesis

Morphology Reproductive morphology Flowers Androecium Stamens

Stamens equal; filaments flat, fused to each other forming a ring, 0.3–0.8 mm long, pubescent to glabrescent; anthers yellow, 5.5–7 × 0.6–1.3 mm, connivent to form a bottle-shaped cone 5–8 × 1.8–3.6 mm with sterile beak, dehiscing by lateral fissures from apex of fertile section

Morphology Reproductive morphology Flowers Gynoecium Ovary

Ovary usually bilocular but plurilocular with false septa in cultivated varieties, 1.3–1.6 × 1.8–2 mm, ridged, glabrous; style straight, 5.5–7.3 × 0.2–0.4 mm, hairy in lower part, usually included, occasionally exserted to 1 mm; stigma green, capitate, sometimes bilobed, 0.2–0.8 × 0.3–0.5 mm

Morphology Reproductive morphology Fruits

Fruit red, orange or yellow, globose, ovoid to pyriform berries, 1–10 cm diameter, often depressed or irregularly lobed, glabrous and smooth, pericarp thick, sweet-tasting

Morphology Reproductive morphology Seeds

Seeds usually > 100, yellow to light brown, elliptic-ovoid, 3–3.8 × 1.7–2.4 mm, flattened, verrucate, often covered with the remnants of strands of thickening appearing as pseudo-hairs, enclosed in mucilage; sclerotic granules absent.

Ecology

Widely cultivated, and a common to occasional escape on roadsides and in waste places, frequently near habitation; often naturalised on river banks, in marshy areas, woodland, forest areas and open places; spread by birds and baboons; 750–2000 m

Note

Commonly known as the Tomato, Golden- or Love-apple, this species is one of the most important global vegetables which is cultivated in most tropical and temperate countries, but which is now only known in cultivation. Over 500 cultivars have been bred resulting in enormous variations in fruit size, shape and colour. The small-fruited L. esculentum Mill. var . cerasiforme (Dunal) Alef., for example, is commonly known as the cherry tomato. The fruits are eaten raw or cooked, with commercial tomato sauce being made from the berry flesh, while the leaves are used as a vegetable. The species probably originated in Peru or Ecuador from where, in pre-Colombian times, it could have spread north as a weed (cf. Mansfeld, 2001). The considerable morphological diversity found in Mexico suggests that it was first domesticated there, and this may have been the source of the first tomatoes to reach Europe (cf. Heiser, 1969). It is widely grown thoughout Africa; in the floral area it is cultivated for home consumption, and for sale in both local markets and the cities. Nevertheless, African herbarium specimens of this species are rare even though the tomato is considered to be the most important vegetable crop in most West African countries (Rouamba in van den Berg et al. (eds), Solanaceae V: 245–250 (2001)). An extensive list of synonyms of this species – as Lycopersicon esculentum - is given in Mansfeld (2001) together with a bibliography of relevant references and in the more recent publication by Peralta et al. (2008). This species and related taxa contain steroidal glycoalkaloids, with the major component being α-tomatine.
