Description

edit

Vegetative characteristics

edit

It is a bulbous, perennial,[3] terrestrial herb[4] with ovate,[5][6] tunicate, up to 7.5 cm wide bulbs bearing 5-7,[7] dark green,[8][9] oblong,[3] glabrous, petiolate[10][11] 20 cm long, and 5-7 cm wide leaves[11] with an acute or acuminate apex.[4] The leaves have a lattice-like venation.[11][6][3] The midrib of the leaf is prominent on the underside of the leaf.[11]

Generative characteristics

edit

The up to 60 cm long umbellate inflorescence,[7] which exceeds the leaves in its height,[6][7] bears up to seventeen blue-violet flowers lacking fragrance.[7] The cylindric scape is unstreaked and turns red towards the base.[11] The flowers have 6[12][13] 7 cm long,[7] lanceolate tepals[14] with an acute apex. The tepals are blue to violet towards the apex, but they are white at the base.[7] The flower has 6 stamens[4] with whitish anthers,[14] which are shorter than the tepals. The upper stamen is erect and the other five are pointing downwards.[11][7] The trilocular ovary is subglobose. The stigma is simple.[11] The ovoid or obovoid,[4] trivalvular capsule fruit[15] bears 1–3[7] rounded, dark brown,[8] large and fleshy seeds.[16] Within Griffinia subgenus Griffinia, it has the largest flowers.[2] Flowering occurs in the period of March through April. Up to five flowers may be open at the same time and they last for approximately one week.[7]

Reproduction

edit

Generative reproduction

edit

Flower and fruit formation in its natural habitat occurs in March to April. Infructescences with 1-7 fruits are formed.[10] Each pear-shaped fruit contains 1-3 seeds. Germination occurs within a period of 1-3 months and the seedlings reach maturity within 3-4 years.[10][7]

Vegetative reproduction

edit

Vegetative reproduction occurs through bulbils, which form clusters around the mother plant.[10]

Taxonomy

edit

This species was first described in 1817 as Amaryllis hyacinthina Ker Gawl. by John Bellenden Ker Gawler. Three years later he transferred it to Griffinia as Griffinia hyacinthina (Ker Gawl.) Ker Gawl.[1] It is the type species of its genus.[17]

Etymology

edit

The specific epithet hyacinthina means blue-coloured.[18] The flowers are hyacinthine blue.[11]

Habitat

edit

This species of Griffinia grows in a very specific habitat. It requires the warmth, deep shade and high humidity of the tropical rainforest where the floor is covered with large quantities of organic matter. Like related species, G. hyacinthina is endemic to Brazil. It is native to the south-eastern part of the country, specifically the Atlantic Forest.

Conservation

edit

This species is endangered.[4][10] It is threatened by extinction, due to habitat destruction.[10]

Cultivation

edit

It should be cultivated in well draining soils with a high proportion of organic material.[10] It is a slowly growing species.[19]
