Contents

Dracaena aletriformis is commonly known as the large-leaved dragon tree. These plants are found in forest in the eastern areas of South Africa from Port Elizabeth to northern and eastern Limpopo. [2] They are also found in Eswatini, [2] but are most common in the coastal and dune forests of KwaZulu-Natal. [3]

Taxonomy

This plant has 8 synonyms. [1] In the APG III classification system, the genus Dracaena is placed in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae). [4] It has also been placed in the Agavaceae (now the subfamily Agavoideae) and the Dracaenaceae. Like many lilioid monocots, it was formerly placed in the family Liliaceae (lily family). [2]

Description

Single stemmed or branched (usually at the base). The leaves are large and strap-shaped in rosettes at the tips of the stem/s. The leaves are leathery, shiny, and dark green, with whitish margins. These plants may grow up to 4 metres (13 ft) tall. The flowers are produced on a much branched flowering head. The flowers are silvery-white and described as sweetly or strongly scented. [3] [2] The two-lobed berry-like fruit ripen to a reddish-orange colour.

Ecological significance

The flowers open from late afternoon to early morning and attract night-active pollinator moths. Birds eat the fruit; helping to remove the orange pulp which contains a growth inhibitor that otherwise slows germination of the seeds. [2] Snails and the larvae of the Bush Night Fighter butterfly, Artitropa erinnys , feed on the leaves. [2] [5] Birds and mice nest among the leaves of these plants. [3]

<span class="mw-page-title-main">Asparagales</span> Order of monocot flowering plants

Asparagales is an order of plants in modern classification systems such as the Angiosperm Phylogeny Group (APG) and the Angiosperm Phylogeny Web. The order takes its name from the type family Asparagaceae and is placed in the monocots amongst the lilioid monocots. The order has only recently been recognized in classification systems. It was first put forward by Huber in 1977 and later taken up in the Dahlgren system of 1985 and then the APG in 1998, 2003 and 2009. Before this, many of its families were assigned to the old order Liliales, a very large order containing almost all monocots with colorful tepals and lacking starch in their endosperm. DNA sequence analysis indicated that many of the taxa previously included in Liliales should actually be redistributed over three orders, Liliales, Asparagales, and Dioscoreales. The boundaries of the Asparagales and of its families have undergone a series of changes in recent years; future research may lead to further changes and ultimately greater stability. In the APG circumscription, Asparagales is the largest order of monocots with 14 families, 1,122 genera, and about 36,000 species.

<span class="mw-page-title-main">KwaZulu-Natal Dune Forest</span> Subtropical forest type from the coastal dunes of KwaZulu-Natal, South Afric

KwaZulu-Natal Dune Forest is a subtropical forest type that was once found almost continuously along the coastal dunes of KwaZulu-Natal, South Africa. This vegetation type develops in sheltered areas behind the littoral zone, where with some protection from the salt wind it may develop with canopies as tall as 30 m. It still exists in protected areas, but much has been degraded by human activity. Coastal dune forest covers approximately 1% of the land area of KwaZulu-Natal, and is a habitat type seriously threatened from human population pressure and development, particularly titanium mining.

<span class="mw-page-title-main">Families of Asparagales</span>

The Asparagales are an order of plants, and on this page the structure of the order is used according to the APG III system. The order takes its name from the family Asparagaceae and is placed in the monocots. The order is clearly circumscribed on the basis of DNA sequence analysis, but is difficult to define morphologically, since its members are structurally diverse. The APG III system is used in World Checklist of Selected Plant Families from the Royal Botanical Gardens at Kew. With this circumscription, the order consists of 14 families with approximately 1120 genera and 26000 species.
