Portea is a genus in the plant family Bromeliaceae, subfamily Bromelioideae. It is native to the Atlantic coast of Brazil.

Contents

The genus is named for Dr. Marius Porte, [1] a nineteenth-century French naturalist who died in 1866, in Manila, while on a specimen-collecting expedition for the French National Museum of Natural History. [2]

Characteristics

Portea is a small genus of New World plants, and according to the Bromeliad Binomial,[ clarification needed ] currently includes nine species. The bromeliads are endemic to the eastern Atlantic coast of Brazil, where the sea breezes, marine layer, adequate precipitation and year-round favorable temperatures can see these plants grow upwards of 5 feet (1.52 m) or taller, especially when blooms are accounted for.[ citation needed ]

They thrive in most lighting conditions, from bright shade to strong, indirect light as well as all-day sun or partial sun, being one of the bromeliad genera that does best in full sun. More light results in better leaf form, color; additionally, adequate lighting triggers repeat, annual flowering cycles, sometimes blooming twice in a year. The tall, profuse inflorescences are often dripping with nectar, and are frequented by many hummingbirds, sunbirds and other pollinators.[ citation needed ] The foliage of this genus often is quite attractive, if not simple in its lime-chartreuse green hue. Increased sunlight and slightly decreased moisture can give an appealing, “sun-stressed” reddish-bronze shade to the leaves, as can cooler autumn and winter temperatures. The length of the inflorescence is rather impressive, measuring nearly 3 feet (1 meter) long, eventually “drooping” slightly, from the weight of the flowers and berries (once pollinated), adding to the plant’s impressive stature as a whole.

As with many bromeliads, the leaves’ perimeters are lined with tiny, saw-like “teeth”, which, while not dangerously sharp—such as the spines of a Dyckia or Hechtia —, may cause an itchy reaction in the skin if contact is made. This is due to the natural presence of bromelain, an enzyme found among the Bromeliaceae and commonly used in digestive supplements. This enzyme is most prevalent, however, in pineapples (genus Ananas ), another type of bromeliad. [3]

<i>Catopsis berteroniana</i> Species of carnivorous plant

Catopsis berteroniana, commonly known as the powdery strap airplant or the lantern of the forest, is an epiphytic bromeliad thought to be a possible carnivorous plant, similar to Brocchinia reducta, although the evidence is equivocal. Its native range is from southern Florida to southern Brazil. It generally grows on the unshaded twigs of trees, and has been shown experimentally to trap more insects in its tank than other bromeliads of comparable size. There are several other species in the genus, none of which is believed to be carnivorous.
