Like most monocots, orchids generally have simple leaves with parallel veins, although some Vanilloideae have reticulate venation. Leaves may be ovate, lanceolate, or orbiculate, and very variable in size on the individual plant. Their characteristics are often diagnostic. They are normally alternate on the stem, often folded lengthwise along the centre ("plicate"), and have no stipules.
|
|
The hybrid is generally intermediate in appearance between its parent species. Raised ribs line the inner edge of the peristome and end with elongated teeth. These are more prominent than those found in N. rajah and smaller than those of N. villosa. The peristome is coarse and expanded at the margin (but not scalloped like that of N. rajah), the lid orbiculate or reniform and almost flat.
|
|
The tiny seeds are explosively expelled. Plants acaulescent or nearly so. The stems, if any, are very short and covered with persistent petiole bases. Leaves are often very numerous and crowded. Stipules persistent; petiole 8–25 cm. Leaf blade long-petiolate, oblong-ovate, deltate- ovate, or orbiculate, entire or deeply pinnately or almost palmately lobed, 6-20 × 7–22 cm, sparsely scabrous or pubescent.

In the wild, there is a great deal of variety in flower colour. Like other irises, it has 2 pairs of petals, 3 large sepals (outer petals), known as the 'falls' and 3 inner, smaller petals (or tepals), known as the 'standards'. The falls are orbiculate (or circular) or pendulum shaped, with a maroon or reddish, signal patch, and red, or brown veining. They also have brown spots.

These are more prominent than those found in N. rajah and smaller than those of N. villosa. The peristome is coarse and expanded at the margin (but not scalloped like that of N. rajah), the lid orbiculate or reniform and almost flat. In general, pitchers are larger than those of N. villosa and the tendril joins the apex about below the leaf tip, a feature which is characteristic of N. rajah.Clarke, C.M. 2001.

Indo- Pacific sergeant or damselfish in Sea of Dibba, Fujairah, UAE Pomacentrids have an orbiculate to elongated body shape, which is often laterally compressed. They have interrupted or incomplete lateral lines and they usually have a single nostril on each side (some species of Chromis and Dascyllus have two on each side). They have small- to medium-sized ctenoid scales. They have one or two rows of teeth, which may be conical or spatulate.

The Dvorska house was given the okay to build Kursalón on April 18, 1837. Preparation to build the saloon started in 1837, and construction began in spring 1838. Some problems arose during construction; there was a wide orbiculate roof from which streams of water fell down when the weather was rainy. Inconveniently used wood was placed in such a way that planks stuck out and the saloon often needed repair by carpenter and cabinetmaker.

The orbiculate cardinalfish, chubby cardinal, or polka-dot cardinalfish (Sphaeramia orbicularis) is a species of Apogonidae (cardinalfishes). It grows to about 10 cm total length, and has a thin, dark vertical 'waistband' with scattered dark spots toward the tail. It is found in coastal areas throughout much of the Indo-Pacific, including off East Africa, Kiribati, the Ryukyu Islands, New Caledonia, Belau, and the eastern Caroline and Mariana Islands.Froese, R. and D. Pauly, Eds.

The inflorescence is open, brown, up to long with between 3 and 7 distant, distinct spikes per culm. Each spike is ovoid or ellipsoide, typically attenuate at the base and acute or rounded at the tip, with 15–40 lenticular perigynia. The perigynia are green to reddish brown, orbiculate to broadly ovate, and typically long and across (1.2–1.8 times as long as wide). Carex brevior flowers in mid-May and early June, fruiting in the early to mid summer.

Leaves of Acer chaneyi are simple in structure, with perfectly actinodromus vein structure and are widely ovate to orbiculate in shape. The leaves are deeply dissected, occasionally into three lobes but more typically into five. The upper lateral lobes are two thirds as long as the median lobe, and all the lateral lobes are elliptic in outline. The leaves have between five and eleven secondary veins which diverge from the basal region of the primary vein at angles ranging from 25° to 50°.

These are more prominent than those found in N. rajah and are clue as to the hybrid's parentage (N. villosa has highly developed peristome ribs). The peristome is coarse and expanded at the margin (but not scalloped like that of N. rajah), the lid orbiculate or reniformed and almost flat. In general, pitchers are larger than those of N. villosa and the tendril joins the apex about 1–2 cm below the leaf tip, a feature which is characteristic of N. rajah.Clarke 2001b, p. 19.

New caudexes are generated each year by the current years plant and the old caudex withers away in the fall and early spring of the next year. In early spring plants grow, producing glabrous or glandular leaves. both basal and cauline leaves are produced that have long petioles. Leaf blades are 1-4×-ternately compound with leaflets reniform or cordate to obovate or orbiculate in shape. The leaflets are 10–45 mm wide with lobed margins often crenate, and the undersides are normally glabrous or glandular.

Leaves of Acer smileyi are simple in structure, with perfectly actinodromus vein structure and are generally orbiculate to suborbiculate in shape. The leaves are five-lobed with the basal two lobes small while the upper lateral lobes are almost as long as the median lobe and all lobes being triangular in outline. The leaves have five primary veins and range between long by wide in overall dimensions. A. smileyi has small teeth while the lobes have a distinct and complex bracing of veins formed by the joining of two external secondary veins.

Species of violet are the host plant for larval S. mormonia. There is currently no evidence for a particular species of violet being preferred as a host plant, and S. mormonia has been observed feeding on many species of violet, including Viola dunce, Viola canadensis, Viola glabella, Viola nephrophylla, Viola orbiculate, and Viola renifolia. Violets flower before the peak flight season, meaning that its function as an adult nectar source is limited. Adult feeding also takes place at mud puddles, specifically by males and older females, and on nectar from Compositae plants.

There has been confusion surrounding N. stenophylla and N. fallax ever since the latter was first described. Nepenthes fallax matches N. stenophylla in most respects, except for the shape of the lid; the type specimen of N. fallax has an orbiculate lid, whereas that of N. stenophylla is narrow. However, the original description of N. stenophylla was based on a plant raised from seed in a greenhouse in England, and the narrow shape of the lid could be an aberrant characteristic resulting from artificial growing conditions. In his seminal monograph "The Nepenthaceae of the Netherlands Indies", B. H. Danser treated N. fallax as a heterotypic synonym of N. stenophylla.Danser, B.H. 1928.
