Homosporous, with sporangia borne singly and dehiscing by a single slit.

Warty fruits, 1 cm wide, often dehiscing on the tree.Leaves and fruits.
|

Anthers dehiscing via pores. Fruit fleshy, a small berry. The fruiting carpel indehiscent and baccate. Fruit enclosed in the fleshy receptacle, 1 seeded.
|
|
Capsules dehiscing only partway from apex to base, 30–100 × 2–4 mm, glandular-hirsute. Seeds light brown, 1.2–1.8 × 1–1.2 mm, finely ridged transversely.
|
|
The fruit is a thin walled elastic follicle dehiscing by a single longitudinal suture. There are several seeds per carpel, that are obovoid with a pair of basal-lateral expansions.
|
|
The androecial members are all equal. The androecium just presents two fertile stamens with sessile anthers dehiscing by longitudinal slits. The pollen is polysiphonous and its grains are three-celled and nonaperturate. The gynoecium (2–)4(–16) is superior, carpelled, and euapocarpous.
|
|
The anthers are oblong in shape and around in length, dehiscing longitudinally at maturity. The ovary is conical, bearing styles that are approximately long. The stigma is discoidal and somewhat dehiscent at maturity. Insect pollinators of the plant include flies, honeybees, and ants.
|
|
The conidia are thick-walled, globose to barrel-shaped, brown to black, and typically found with coarse surface ornamentation, dehiscing by schizolysis. Ramoconidia are absent. Colonies on MLA grow slowly and are dark in pigmentation. Synanamorphs are absent during its asexual reproduction stages.
|
|
Pistils are depressed globose or depressed trapezoidal in shape, 1-locular and with many ovules. Stamens consist of short filaments with thecae at the tip, dehiscing by a pore. Pollens squeezed out from the theca pore like a droplet. Fruits are berries with round to ellipsoidal shapes.
|
|
Fertile stamens 5 to 10 or numerous, rarely one. Filaments sometimes persistent, sometimes narrowed near the anthers. Anthers basifixed or slightly dorsifixed, usually dehiscing by one or two apical or subapical pores, sometimes latrorsely by longitudinal slits. In Medusagyne and Quiinoideae, an enlarged septum separates the thecae.

|
The tree bears its fruit, which are aromatic, cone-like, aggregate infructescenses, about 4 cm in length, in July and August. There are approximately 25 fruits of dehiscing capsules per infructescense. The fruit's seeds are exserted, and covered with bright networks of arils which dangle from threads. Seed germination is epigean.

|
Ovary glabrous; style 7–9 mm long, longer than the smaller stamens, cylindrical, glabrous, curved near apex, closely appressed to the larger stamen; stigma capitate. Fruits 0.8–1.5 cm in diameter, globose berries, greenish white when immature, translucent at maturity, drying light-brown to blackish, glabrous, the mesocarp watery and held under pressure, dehiscing explosively at maturity, normally between two calyx lobes.
|
|
Fruits capsular, small, 3-lobed, soon dehiscing septicidally into 3 bivalved cocci; generally surrounded by the accrescent female bract. Seeds small, ovoid or ellipsoid, usually carunculate, smooth or foveolate; endosperm present, whitish; the embryo straight; cotyledons broad and flat. Allomorphic female flowers present in some species, generally terminal (sometimes median or basal) in the inflorescences; ebracteate, long pedicellate or subsessile; calyx as in the normal female flowers; ovary and fruits 1-2 locular.

Two outlying restricted populations are known in the Cannabullen Falls and Mount Lewis areas. A. bidwillii has a limited distribution within Australia in part because of the drying out of Australia with loss of rainforest and poor seed dispersal. The remnant sites at the Bunya Mountains and Mount Lewis in Queensland have genetic diversity. The cones are large, soft-shelled and nutritious and fall intact to the ground beneath the tree before dehiscing.

Five carpels are joined, forming the spokes of a wheel some 30 cm in diameter. They are woody and densely studded with hard, blunt spines, dehiscing on one side to reveal large (25 mm long), black seeds, which are rich in oil and, after roasting, are a valuable food source. Stinging hairs, common in the Malvaceae, coat the interior of the carpels and these may irritate skin and eyes. The carpels have a superficial resemblance to the Northern Hemisphere Chestnut.

The pods contain many seeds small flattened seeds that are winged at both ends. It is similar to Cercidiphyllum japonicum, but can be distinguished by a combination of the following characteristics: C. magnificum is a smaller tree that typically has only a single main trunk (vs. large, canopy-forming, with multiple trunks); the leaves are more deeply crenated; the follicles have partially dehisce, with slightly recurved tips (vs. follicles fully dehiscing and strongly recurving tips); grows at a higher elevation, rarely co-occurring with C. japonicum.

The calyx usually has four or five lobes; the corolla tubular, two-lipped or five-lobed; stamens number either two or four, arranged in pairs and inserted on the corolla, and the ovary is superior and bicarpellated, with axile placentation. The fruit is a two-celled capsule, dehiscing somewhat explosively. In most species, the seeds are attached to a small, hooked stalk (a modified funiculus called a jaculator or a retinaculum) that ejects them from the capsule. This trait is shared by all members of the clade Acanthoideae.

The sexual stage of N. vriesii consists of a whitish tumble-weed like fruiting body which is approximately 1 mm in diameter and a central cluster of asci containing ascospores. The hyphae which consist of exterior fruiting bodies, are characteristically rough-walled with septal constrictions. The lens shaped ascopores are brown in color and range in size from 2-3 μm. Like other members in the family Onygenacae, N. vriesii produces rhexolytically dehiscing conidia which can be either teardrop shaped or club-shaped, and form directly on the sides of the hyphae.

They were erect or arched, dichotomized (forked) occasionally, and had adventitious roots arising directly from prostrate stems. As in Asteroxylon the vascular bundle in the stems was an exarch actinostele, with a star-shaped arrangement of tracheids of a primitive annular or helical type (so-called G-type). Leaves were unbranched strap-shaped microphylls (4 cm long in B. longifolia) with a single prominent vascular thread, arranged spirally on the stem. The sporangia were borne in the axils of the leaves, broader than long, dehiscing by a transversely-orientated slit.

Fevillea cordifolia, also known as javillo and antidote caccoon, is a climbing vine of up to 20 m of the family Cucurbitaceae and occurring in South and Central America in Bolivia, Brasil, Colombia, Costa Rica, Ecuador, Nicaragua, Panama, Peru and Venezuela.Smithsonian Tropical Research Institute This dioecious species produces a globose, green fruit some 12 cm in diameter, dehiscing along a line about 2 cm from its base.Encyclopedia of Life Its leaves are 8-16 by 5.5–12 cm, entire, ovate-triangular or with 3-5 lobes, with axillary tendrils. Lax panicles are 10–15 cm long.

Calochortus) and may be united into a tube. Nectar is produced in perigonal nectaries at the base of the tepals. ; Androecium : Six stamens in two trimerous whorls, with free filaments, usually epiphyllous (fused to tepals) and diplostemonous (outer whorl of stamens opposite outer tepals and the inner whorl opposite inner tepals), although Scoliopus has three stamens opposite the outer tepals. The attachment of the anthers to the filaments may be either peltate (to the surface) or pseudo-basifixed (surrounding the filament tip, but not adnate, that is not fused) and dehisce longitudinally and are extrorse (dehiscing away from center).

Typically the lifespan of a single Strobilanthes callosa bloom lasts between 15 and 20 days and its mass blooming usually extends from mid-August to September-end. After the mass flowering, the shrub is covered with fruits which are dry by the next year. With the coming of the monsoon and the first rains in the next year, the dried fruits absorb moisture and burst open with a pop, the hillsides where Strobilanthes callosa grows are filled with these loud popping sounds of dried seed pods bursting open somewhat explosively dehiscing their seeds for dispersal and soon new plants germinate taking root in the wet forest floor.
