The stem is erect, solitary, unbranched and glabrous. The basal leaves are usually longer than inflorescence or rarely equal. They are fistular, glabrous, 15 to 20, up to 28 cm long, 1 to 1.5 mm wide. One cauline leaf, oblong-lanceolate, is cucullate and glabrous.

The capsule of the sporophyte is inclined, curved, bilaterally symmetric and about 1.5 mm. As for the calyptra, it is cucullate, smooth and about 2.5 mm. The spores are about 3-22 µm. Since it is a member of the Bryopsida class it also has arthrodontous peristome teeth which aid in spore dispersal.

The flower is bilateral in shape, with two large petal-like sepals on the sides, often called the "wings", and three smaller sepals behind. There are three petals in shades of reddish purple, yellow or white, which are joined at the bases. The lower of the three is the keel petal, which is "boat-shaped, cucullate [hood- like], or helmet-shaped". The keel petal may have a beak or a fringe on the tip.

Gills are distantly spaced The cap is white and small, with a diameter typically ranging from . Initially convex to cucullate (hood-shaped), it flattens during maturity, developing visible surface grooves that correspond to the gills underneath the cap; the surface may also be covered with glistening particles, remnants of the partial veil. The cap is pallid gray with a whitish margin when young, but soon becomes white overall. The flesh is membranous, fragile, and thin (less than 0.5 mm).

The tepals are very succulent, and fused together for 1/2 to 2/3 of their lower length. The free lobes of the tepals are also very succulent, curve inwards, are coloured green with hyaline margins, and somewhat cucullate. Thus the lowermost 1mm part of the flower forms a compact cone, and higher up this cone widens out into a bowl-like structure. The perfect flowers have five stamens, are weakly protandrous, fig-shaped, about 2 to 2.5 in length, 2.5 to 3mm in diameter, have a deeply divided perianth, and are somewhat round-shaped.

Hypericum terrae-firmae is a shrub or small tree, 1–2 m tall, erect, with branches strict, pseudo-dichotomous or lateral. The stems are orange-brown, 4-lined when young, soon terete, without corky wrinkles, the cortex is exfoliating in strips, the internodes are 4–6 mm long. The leaves are sessile, free from the base, spreading to subimbricate and tetrastichous, deciduous at the base without fading. The lamina are 16–30 mm long and 4–6 mm wide, narrowly oblong to narrowly elliptic, plane, not cucullate or carinate, concolorous, not or slightly glaucous and chartaceous to thinly coriaceous.

Kaikaia gaga is a darkish purple and red with two horns jutting out the top, which have been compared to shoulder pads. An excerpt from the Zootaxa paper detailing Kaikaia's appearance: > Kaikaia is particularly notable in having an assemblage of features more > characteristic of the Old World centrotine tribe Beaufortianini than > currently recognized New World centrotine tribes. Kaikaia lacks cucullate > setae of the mesothoracic femora, which are present in the Boocerini and to > some extent, the Platycentrini. The new genus also has an additional m-cu > crossvein in the forewing, as well as a frontoclypeal shape and overall > appearance similar to Platycentrus Stål.

Dicerandra modesta (Lamiaceae): Raise in rank for a disjunct perennial in a new coastal clade in Florida. J Bot Res Inst Texas 2:2 1163. The phylogenetics of this genus have been studied before; first by Robin Huck in 1987, who described Section Dicerandra, which includes all species with standard-lobed corollas and exserted stamens, and section Lecontea which includes D. odoratissima and D. radfordiana that have cucullate-lobed corolla species with inserted stamens. Subsequent studies by plant systematists at the University of Florida have confirmed these sections, in addition to discovering a potential chloroplast capture event in Dicerandra immaculata var savannarum.

Epipactis helleborine var. youngiana is a perennial herb that typically grows high. It differs from typical E. helleborine in having its basal leaf more than 1.2× as long as broad rather than 1.1× as long as broad, in the basal leaf being "flat, flaccid, unribbed, silky to [the] touch, margins undulate" ("cucullate, stiff, ribbed, coarse to [the] touch, margins not undulate" in E. helleborine), in its flowers – when coloured – being clear pink rather than dirty pink, in the rostellum being nearly as long as the anthers (less than half as long as the anthers in E. helleborine) and in having a shiny ovary with a few stiff hairs, rather than matt with soft hairs or hairless, as in E. helleborine.
