Basic morphological characteristics and representative species of 9 common genera of Bromeliaceae

What are the common varieties of Bromeliaceae plants? Basic morphological characteristics and representative species of 9 common genera

Many members of the Bromeliaceae live perched on the branches of large trees, such as the species of the genus Tillandsia. The fruit of this genus splits open when ripe, and the seeds bearing a plume of hairs drift with the wind, and after landing in a suitable place they begin to sprout and grow. They mainlyuse the scales on their leaves to absorb water and nutrients，the main function of the roots is to anchor the plant. Home growers have described it as "having a real air of wandering." Tillandsia usneoides looks like the lichen Usnea; when cultivated it only needs to be hung in the air, and water and fertilizer supplied by misting, and it will grow very luxuriantly. It is the best representative of this genus. The genus Neoregelia is not grown mainly for its flowers; the main ornamental part is the brilliantly colored leaves at the center of the plant, and the more brightly lit the location, the more vivid the leaf color. The leaf bases of this type of bromeliad can accumulate water, and they are often called tank bromeliads; in their native habitat, small creatures such as frogs and insects often make their home there. When the Panama Canal was being dug, disease ran rampant, and in order to reduce mosquito breeding, this type of bromeliad was extensively eradicated. Neoregelia carolinae is a relatively common species in this genus. Neoregelia carolinae is a relatively common species in this genus.

Some species of Bromeliaceae can grow very tall. The cheerful genus Guzmania is a representative example. With a height of 60-90 cm and beautiful bracts rising layer upon layer, they wish people career success and steady advancement. The pineapple in the genus Ananas is the best-known species, and after Columbus brought it back to Europe from the West Indies in 1493, it became a widely loved fruit. Although the fruit of its cultivated variety, the variegated pineapple, is also edible, seeing the splendid appearance of its fruit and leaves, few people would have the heart to eat it.

(1) Genus Dyckia

The leaves are hard and spiny, thick and fleshy at the base, arranged in a rosette-forming tank. The inflorescence does not emerge from the tank but is borne in the leaf axils of the lower leaves. The fruit is a capsule, and the seeds are winged. Representative species include Dyckia brevifolia, Dyckia fosteriana, and Dyckia choristaminea.

(2) Genus Ananas

The leaves are linear, spiny, and spirally arranged into a tight tank. Stemless or with an extremely short stem. The ovary is inferior, and the fruit is a syncarp. At the top of the syncarp grows a crown-like tuft of leaves, called the crown. A representative species is Ananas bracteatus. Ananas bracteatus belongs to the genus Ananas and is a horticultural variety of the edible pineapple. The leaves are basal and rosette-forming, and the plant height is 50-80 cm. The leaves are green with yellow stripes along the margins and a reddish blush, sword-shaped, hard, and curved in an arch, with serrated leaf margins. The inflorescence extends from the tank, the flower stalk is upright and pale red, the flowers are purple, and the bracts are fused with the ovary to form a syncarp; at the top of the fruit is a small crown-like tuft of leaves - the crown.

(3) Genus Aechmea

Mainly epiphytes, distributed in Mexico and Argentina. The rosette leaves are leathery yet soft, numerous, spirally arranged into a tank, leathery, often with spots or stripes, and the leaf margins are spiny. The inflorescence is upright or branched, some varieties have clustered corollas, and the margins of the bracts and sepals are also spiny. The ovary is inferior, and the fruit is a berry. Representative species include Aechmea fasciata, Aechmea chantinii, and Aechmea recurvata.

(4) Genus Billbergia

Currently the main ones popular on the market belong to the genus Billbergia, with more than 60 species, mainly distributed in eastern Brazil, from South America to Mexico. The striking pendulous inflorescence is its most important characteristic; stemless, the leaves are spirally arranged into a tank, and the leaf margins are spiny. The inflorescence is racemose or spicate, and there are bracts on the flower stalk. The florets are tubular, and the petals curl back to expose the stamens and pistils. Representative species include Billbergia pyramidalis and Billbergia vittata.

(5) Genus Cryptanthus

The plant is short and small, almost stemless. The rosette leaf cluster spreads flat, forming a star shape. The leaf margins are wavy and undulating, the leaf surface has longitudinal or transverse markings, and the leaf margins have small serrations. The inflorescence is borne in the tank but does not extend beyond it. Representative species include Cryptanthus acaulis, Cryptanthus bivittatus, and Cryptanthus bromelioides.

(6) Genus Neoregelia

Distributed in Brazil, Peru, and eastern Colombia. The leaf color is richly varied, often with colorful spots or stripes, spirally arranged into a shallow and broad tank, the leaf margins are spiny, the leaf tips are rounded, and the leaf apex turns upward. The raceme inflorescence does not extend beyond the tank but sinks within it, and the florets are arranged on the same horizontal plane. Representative species include Neoregelia carolinae and Neoregelia concentrica.

(7) Genus Guzmania

Mostly epiphytic, distributed in the Andean rainforest, and also found in southern Florida, the West Indies, Brazil, and Central America. The leaves are smooth and soft, the leaf margins have no teeth or spines, and they form a water-storing tank. It has the most beautiful inflorescence among bromeliads; many bracts are spirally borne on the flower stalk, forming a star-shaped inflorescence, the florets are hidden among the bracts, and the petals are fused, usually orange, and can last for several months. A representative species is Guzmania lingulata.

(8) Genus Vriesea

Epiphytic bromeliads, distributed from the West Indies to Mexico and Argentina. Rosette leaves, the leaves smooth, entire, with transverse markings, forming a water-storing tank. The inflorescence is spicate, the bracts are arranged in two overlapping rows, the petals are separate, usually with a waxy sheen, and the flowers can remain open for several months. The ovary is superior, and the fruit is a capsule. Representative species include Vriesea splendens and Vriesea carinata.

(9) Genus Tillandsia

The leaves are entire and spineless, with well-developed absorbing scales. The inflorescence is spicate, and the bracts are arranged in two overlapping rows. The petals are fused. Representative species include Tillandsia cyanea and Tillandsia usneoides.
