Marantaceae

(Family)

Overview

[ Back to top ]

Herbs perennial, rhizomatous. Aerial stems present or absent. Leaves distichous, usually large; petiole sheathing at base, apex with a swollen pulvinus; leaf blade pinnately veined, lateral veins parallel, slightly S-shaped. Inflorescences terminal or axillary, borne on leafy shoots or occasionally on separate, leafless shoots from rhizomes, compound, headlike, spicate, or diffuse and much branched, bracteate; bracts each subtending a pair of flowers or a cincinus of paired flowers. Flowers bisexual, asymmetric, paired or rarely borne singly. Sepals 3, free. Corolla lobes 3, often slightly unequal, basally connate into a tube. Staminodes and stamen in 2 whorls: outer whorl with 1 or 2 petaloid staminodes, rarely absent; inner whorl with 1 hooded (cucullate) staminode enclosing terminal portion of pistil at anthesis and bearing a lateral appendage (trigger), 1 thickened and fleshy (callose) staminode, and 1 fertile stamen narrowly petaloid laterally; anther 1-loculed. Ovary inferior, 3-loculed, 1--3 locules fertile; ovules 1 per locule. Style cylindric, adnate to inside of corolla and staminode tube, free portion curved after explosive forward movement (tripping) when released Seeds 1--3, hard, usually arillate.from hooded staminode; stigma scoop-shaped or blunted and 3-cleft. Fruit a capsule, loculicidal, rarely indehiscent or berrylike.

Thirty-one genera and ca. 525 species: pantropical but ca. 80% in America, absent from Australia; four genera (one introduced) and eight species (two endemic, one introduced) in China.[1]

Calathea

Calathea is a genus of plants belonging to the family Marantaceae. There are several dozen species in this genus. Native to the tropical Americas, many of the species are popular as pot plants due to their decorative leaves and, in some species, colorful inflorescences. They are commonly called calatheas or (like their relatives) prayer plants. Several cultivars, e.g. Calathea cv. 'Silver Plate', have been bred. [more]

Phrynium

Rhizomes creeping. Basal leaves 1 or more; cauline leaf 1 or absent; leaf sheath and petiole long. Inflorescences borne basally or above an elongate internode on leafy shoots, subtended by a cauline leaf or a reduced, bladeless sheath, compound, capitate, often with additional spikes borne in axils of basal bracts of initially produced spike and later additional ones in basal bracts of secondary spikes, often in a very compact, congested group of few to many small spikes; bracts spirally arranged, often shredding into fibers after anthesis, at least at apex. Flower pairs 2 to many per bract. Sepals usually longer than corolla tube, membranous. Corolla tube proximally solid, distally hollow; lobes 3, oblong, subequal. Outer staminodes 2, obovate, staminode tube longer than corolla tube; callose staminode wholly callose, not petaloid at apex. Style curved after tripping; stigma enlarged, blunted. Fruit globose to ellipsoid, dehiscent, often late dehiscent; pericarp hard. Seeds 1--3; aril membranous.[2] [more]

Phyllodes

In , the petiole is the small stalk attaching the leaf blade to the stem. The petiole usually has the same internal structure as the stem. Outgrowths appearing on each side of the petiole are called stipules. Leaves lacking a petiole are called sessile, or clasping when they partly surround the stem. Clasping leaves of the Poaceae have an extra structure called the ligule. Petiolate leaves are ones where the petiole connects to the leaf before its apex. [more]

Stachyphrynium

Rhizomes creeping. Basal leaves 1 or more; cauline leaves absent. Inflorescences borne terminally on leafy shoots or on separate, leafless shoots arising directly from rhizomes, spikelike, ellipsoid or spindle-shaped to subcylindric, usually laterally compressed; bracts distichous, usually herbaceous. Flower pairs 1--5 per bract. Sepals less than 1/2 as long as corolla tube, usually much shorter, membranous. Corolla proximally ± solid, distally hollow; lobes 3, oblong, subequal. Outer staminodes 2, obovate; callose staminode wholly callose, not petaloid at apex. Ovary often 2-loculed by abortion. Style cylindric, curved after tripping; stigma enlarged, blunted. Fruit ellipsoid, dehiscent. Seeds usually 2; aril reflexed, 2-lobed.[3] [more]

Thalia

Plants aquatic, upright, often dying back to rhizome in winter [dry season], 1--3.5 m. Rhizome not evidently enlarged or specialized for starch storage. Stems unbranched below inflorescence; leaves all basal or rarely with single cauline leaf borne above elongate (0.7--2.5 m) internode. Leaves homotropic; sheath not auriculate, spongy, containing prominent air spaces; blade plain green, ovate to elliptic. Inflorescences branched, branches short and upright to elongate and arching; rachis internodes conspicuously zigzagged; bracts deciduous, both bracts and prophylls falling with flower if fruit not set, leaving proximal portion of rachis bare, each bract subtending 1 flower pair, herbaceous to leathery; prophylls not evidently keeled, membranous; secondary bracts absent; bracteoles absent. Flowers self-fertilizing [outcrossing], pale to dark purple (corolla and staminodes) ; sepals persistent in fruit, 0.5--3 mm, membranous; corolla tube 1--6 mm, corolla lobes subequal to strongly unequal; outer staminode 1, petal-like, showy; callose staminode mainly fleshy, narrow apical rim petal-like; cucullate staminode with 2 appendages, subterminal, finger-like; stylar movement helical when tripped; styles with 1 appendage, elongate, straplike. Fruits capsules, 1-seeded, nearly globose to ellipsoid, pericarp thin, indehiscent. Seeds dark brown, nearly globose or ellipsoid, smooth; perisperm canals 2, curved; aril reduced. x = 6.[4] [more]
