Pinguicula filifolia, is a carnivorous species of plant found predominantly in western Cuba and some of the neighboring regions. It was discovered by Charles Wright in 1866. It is a tropical plant that uses sticky secretions on its leaves to catch small insects, pollen, and other plant debris to help supplement its own nutrition. [1] It thrives in swamp like white sand savannahs with high temperatures and humidity.

Contents

Distribution

Pinguicula filifolia covers a more broad ecological area than all other Pinguicula in the Archipelago. They range from the Pinar del Rio province in the island of Cuba to the island of Isla de la Juventud. These two areas are separated by the sea; plants grow near the coastlines and the swamp like white sand savannahs that they inhabit. P. filifolia appears only at low altitudes in part due to its affinity to coastal areas, but unlike some of the other Pinguicula species in the immediate area it does not appear in the higher elevations. [2] [3]

Habitat and ecology

Pinguicula filifolia grows in full sun to light shade [2] in a mild soil alkalinity ranging between 7.6 and 7.8. Filifolia thrives in wet soil and flourishes in white sand savannahs and warm temperatures around 30 degrees celsius. [4] The plant prefers high levels of humidity, up to 70%, and experiences much of its growth in the rainy seasons that last between May and November. In addition the plant must tolerate a dry season that lasts between November and April. They maintain a tropical growth rate and thrive near other endemic species due to the partial shade.

Threats

Pinguicula filifolia faces few threats due to its location being so coastal. However, some believe that if the area were to be farmed more heavily P. filifolia may face threats particularly in the Pinar del Rio colonies. [5]

Morphology

Pinguicula filifolia has leaves that are approximately 4–6 mm long and 1-1.5 mm in width with flat or sub-erect leaves while seedlings. These blades arise from rosettes that are 8–10 mm in diameter. A single rosette typically has 4-6 blades sprouting from it. [2]

As Pinguicula filifolia reaches a mature age leaf blades take an erect stance and are linear-filiform. This erect stance helps to avoid rot due to the swamp like nature of the white sand savannahs and also ensures that the plant can stay above water if minor flooding occurs to maintain efficient access to sunlight. Over time, while approaching maturity, the blades narrow to 0.5–1 mm in width and grow to a length of 80–150 mm. their new morphology is cuneate (wedge shaped) at the base of the leaves and becomes acute approaching the apex. [2] Being a carnivorous plant, the leaves are coated with both stalked glands, which secrete a sweet mucilage to attract potential prey, and sessile glands, which are both located on the adaxial surface. [2] During the plants prefoliation phase, the leaves roll up in a circinate fashion, where the tip of the plant curls inward which is believed by some to be used to ensure that its prey cannot escape once caught. [6]

Flowers and fruit

Flowers of Pinguicula filifolia, come in a range of colors; from white to yellow and from blue to purple. [7] [8] They begin to appear primarily in the summer between (July and August) but can flower all year long. Each flower contains 5 petals. [4]

It is one of the most widespread Pinguicula species, being found in mountainous regions from Iceland to the Himalayas. Native to cold climates, it is a temperate species, forming prostrate rosettes of green to red leaves and white flowers in the summer and a tight hibernaculum during a period of winter dormancy in the winter. Like all members of the genus, P. alpina uses mucilaginous glands covering the surface of its summer leaves to attract, trap, and digest arthropod prey.

<i>Pinguicula primuliflora</i> Species of plant

Pinguicula primuliflora, commonly known as the southern butterwort or primrose butterwort, is a species of carnivorous plant belonging to the genus Pinguicula. It is native to the southeastern United States. The typical variety forms a white flower in blooming. Like other butterworts, it has sticky adhesive leaves which attract, capture and digest arthropod prey in order to supply the plant with nutrients such as nitrogen not found in the nutrient poor, acidic soil that it grows in. Its name derives from the fact it is usually the first one to flower in the spring.

Pinguicula chuquisacensis is an insectivorous plant of the genus Pinguicula endemic to Bolivia, where it grows at an elevation of 2400m above sea level. P. chuquisacensis is restricted to the valley of Nuevo Mundo, on one cliff face northeast of Villa Serrano. The species only exists on acidic sandstone formations frequently veiled in fog, growing perennially in open areas. Plant is somewhat erect, with leaves flat upon the growing surface. Hibernacula are absent. The plant possesses 4-6 loblong to ovate-oblong leave, forming a rosette. Flowers small, at 13-15 mm long, including the spur. Plants flower in July, and fruit in November among remaining flowers. The authors have recommended that the species be classified as CR according to criteria B2a+b due to a small area of occupancy and potential and ongoing threats to areas near to and in the immediate area of the cliff side. Genetically, P. chuquisacensis is closest to P. involuta and P. calyptrata (respectively).

<i>Pinguicula orchidioides</i> Species of carnivorous plant

Pinguicula orchidioides is a perennial rosette-forming insectivorous herb native to Mexico and Guatemala. A species of butterwort, it forms summer rosettes of flat, succulent leaves up to 5 centimeters (2 in) long, which are covered in mucilaginous (sticky) glands that attract, trap, and digest arthropod prey. Nutrients derived from the prey are used to supplement the nutrient-poor substrate that the plant grows in. Uniquely among Pinguicula species from the Americas, p. orchidioides produces gemma-like basal buds which elongate into stolons and serve as a means of asexual reproduction. In the winter the plant forms a non-carnivorous rosette of small, fleshy leaves that conserves energy while food and moisture supplies are low. Single purple flowers appear between July and September on upright stalks up to 22 centimeters long.

<i>Drosera derbyensis</i> Species of carnivorous plant

Drosera derbyensis is a perennial carnivorous plant in the genus Drosera and is endemic to Western Australia. Its erect or semi-erect leaves are arranged in a rosette with one or more rosettes emerging from the root stock. The petioles are narrowly oblanceolate, 0.8–1.0 mm wide at the proximate end and 1.3–1.7 mm wide at the apex, narrowing to 0.5–0.7 mm at the laminar base. The petioles are frequently 35–45 mm long when the plant is in flower and are covered in white woolly non-dendritic hairs. The insect-trapping leaf lamina is orbicular and much shorter than the petioles at only 2–3 mm in diameter. The laminar adaxial surface is covered in insect-trapping glands. Each rosette produces 1–4 raceme inflorescences, which are 25–35 cm (10–14 in) long. Each inflorescence bears 30–50 white flowers, with flowering occurring from March to June. The upper portion of the scape and the abaxial surface of the sepals are covered with white woolly non-dendritic hairs. Its roots are fibrous. Drosera derbyensis grows in sandy soils in floodways or near rock outcrops from Derby to Beverley Springs in the Kimberley region.
