Description

Eucomis grimshawii is a short summer-growing bulbous plant, up to 8–10 cm (3–4 in) tall. The bulb is ovoid, about 3 cm (1 18 in) across, with a pale brown outer tunic. The bulb produces four or five leaves, 9–12 cm (3 124 12 in) long and 4–6 cm (1 122 14 in) wide, with flat or slightly undulate margins. The inflorescence is a dense raceme 3–5 cm (1 14–2 in) long, with a variable number of flowers. The flowering stem (scape) is shaded dark maroon or magenta on the lower half, with similarly coloured marks on the upper half. Individual flowers are slightly sweetly scented, with greenish white tepals up to 5 mm (316 in) long. The upper flowers have up to 1 mm (132 in) long pedicels, the lower ones are sessile. The inflorescence is topped by a head or "coma" of 9–16 bracts 15–35 mm (581 38 in) long. The ovary has three locules. The seeds are dull blackish brown. [2]

Taxonomy

Eucomis grimshawii was first described in 2010 by Graham Duncan and Ben Zonneveld, [1] and named after J. Grimshaw who first discovered it in 2002, in the southern Drakensberg, south of Lesotho. E. grimshawii is one of the group of smaller summer-growing diploid species of Eucomis . [2]

E. grimshawii most closely resembles Eucomis schijffii , but is shorter, and has greenish white, sweet-scented flowers rather than dark purple flowers with an unpleasant smell, and pale green rather than glaucous leaves. Both species have dull sculptured seeds rather than smooth glossy ones. [2]

Distribution and habitat

Eucomis grimshawii was found in the Eastern Cape province of South Africa in the Drakensberg Mountains, south of Lesotho, at an altitude of around 2,700 m (8,858 ft). It grows in rich soil, on shady, seasonally wet, south-facing grassy slopes and in boggy conditions. [2]

<i>Eucomis comosa</i> Species of flowering plant

Eucomis comosa, the pineapple flower, pineapple lily or wine eucomis, is a species of flowering plant in the asparagus family Asparagaceae. A deciduous bulbous perennial used as an ornamental plant, it is endemic to South Africa. The white to purple flowers appear in summer and are arranged in a spike (raceme), topped by a "head" of green leaflike bracts.

<i>Eucomis</i> Genus of flowering plants

Eucomis is a genus of flowering plants in the family Asparagaceae, subfamily Scilloideae, native to southern Africa. Most species of this genus are commonly referred to as pineapple flowers or pineapple lilies. They are bulbous perennials with basal rosettes of leaves and stout stems covered in star-shaped flowers with a tuft of green bracts at the top, superficially resembling a pineapple – hence the common names.

<i>Eucomis autumnalis</i> Species of flowering plant

Eucomis autumnalis, the autumn pineapple flower, or autumn pineapple lily, is a species of flowering plant in the family Asparagaceae, subfamily Scilloideae, native to Malawi, Zimbabwe and southern Africa. It is a mid to late summer flowering deciduous bulbous perennial. The flower stem reaches about 40 cm (16 in), rising from a basal rosette of wavy-edged leaves. The green, yellow or white flowers are arranged in a spike (raceme), topped by a "head" of green leaflike bracts. It is grown as an ornamental garden plant and can also be used as a cut flower.

<i>Eucomis vandermerwei</i> Species of flowering plant

Eucomis vandermerwei is a South African bulbous perennial flowering plant, a member of the asparagus family, and like other members of Eucomis is commonly known as pineapple lily for its superficial resemblance to that plant, although not closely related to it. This species is one of the smallest in the genus, and is native to a high-rainfall region of western Mpumalanga in South Africa. The dense rosette of leaves, either prostrate or ascending, is heavily blotched with purple, and the leaf-edges are markedly crisped or wavy. The star-shaped burgundy flowers appear in midsummer, and are borne on a spike (raceme) topped by a "head" of leafy bracts.

<i>Leucospermum muirii</i> The Albertinia pincushion is a shrub in the family Proteaceae from the Western Cape of South Africa

Leucospermum muirii is a rounded, upright, evergreen shrub of about 1½ m (5 ft) high, with a single trunk at its base, that is assigned to the Proteaceae. The flowering branches are 2–3 mm (0.079–0.118 in) thick and are initially grey due to a covering of fine crinkly hairs, which are soon lost. The very narrow spade-shaped leaves of about 5 cm (2 in) long and ¾ cm (0.3 in) wide carry three to seven teeth, and also quickly lose their soft layer of hairs. Its smallish globe-shaped flower heads of 2–3 cm (0.8–1.2 in) in diameter occur with one to four together, each on a stalk of 1–2 cm (0.4–0.8 in) long. It has pale to greenish yellow flowers, becoming orange with age, with some long hairs near their tips, from which straight styles stick out. This gives the flower head the likeness of a pincushion. It flowers from July till October and is pollinated by birds. It is called Albertinia pincushion in English and bloukoolhout in Afrikaans. It is an endemic species that can only be found near Albertinia in the very south of the Western Cape province of South Africa.

<i>Leucospermum royenifolium</i> The eastern pincushion is a shrub in the family Proteaceae from the Western and Eastern Cape of South Africa

Leucospermum royenifolium is an evergreen, spreading or somewhat upturning shrub of up to ½ m high and 1–3 m (3–10 ft) in diameter from the family Proteaceae. It has patent elliptic, eventually hairless leaves. The flower heads are globe-shaped, 1–2 cm (0.4–0.8 in) in diameter, and contain initially whitish, later pinkish, sweetly scented flowers. From the center of the flowers emerge almost straight styles that jointly give the impression of a pincushion. It is called eastern pincushion in English. It can be found flowering between July and December. It occurs in the Western Cape and Eastern Cape provinces of South Africa.

<i>Leucospermum pedunculatum</i> The white-trailing pincushion is a shrub in the family Proteaceae from the Western Cape of South Africa

Leucospermum pedunculatum is an evergreen, low shrub of 15–30 cm (½–1 ft) high spreading from a single stern upright stem, from the family Proteaceae. The powdered or hairless line-shaped to somewhat sickle-shaped leaves are 3–6 cm (1.2–2.4 in) long and 2–5 mm (0.08–0.20 in) wide. The stalked, individually set flower heads are globe-shaped, 2½−3 cm in diameter consist of initially white to pale cream flowers that eventually turn carmine. From the center of the flowers emerge straight styles that jointly give the impression of a pincushion. It is called white-trailing pincushion in English. It flowers from August to January, peaking in September. It is an endemic species that is restricted to a narrow strip on the south coast of the Western Cape province of South Africa.

<i>Leucospermum arenarium</i> Species of srub in the family Proteaceae from the Western Cape province of South Africa

Leucospermum arenarium is a lax, evergreen shrub, with arching and drooping branches, that has been assigned to the family Proteaceae. It has loosely spaced, upright, greyish, narrowly egg-shaped to line-shaped leaves, mostly without teeth and flattened globe-shaped flower heads of 5–7 cm across, consisting of mostly creamy, seldom yellow flowers, that curve in the bud to the center of the head. From the center of the flowers emerge curved styles that jointly give the impression of a pincushion. The common name in English is Redelinghuys pincushion. It only occurs in a very small area in the Western Cape province of South Africa. It flowers between July and October. Unlike in related species the flowers are pollinated by hairy-footed gerbils and striped field mice.
