Senegalia can be distinguished from other acacias by its spicate inflorescences and non-spinescent stipules.

Parry's grama is annual grass that grows tall, although sometimes to . Flowers are born in inflorescences which consist of three to seven spicate branches per culm. They are blue-violet at maturity.
|
|
The blades entire or more frequently dentate or crenate, pinnately or palmately veined. There are several types of inflorescence, terminal or axillary, frequently both, unisexual or androgynous. Male inflorescences spicate, densely flowered, with several flowers at each node subtended by a minute bract. Female inflorescences generally spicate, sometimes racemose or panicle-shaped, with 1–3(–5) flowers at each node, usually subtended by a large bract, increasing and foliaceous in the fruit, generally dentate or lobed; sometimes subtended by a small bract, entire or lobed, non accrescent in the fruit.
|
|
Plants are monoecious. The spicate inflorescences consist of inconspicuous flowers. Male flowers comprise 4-5 perianth segments and 4-5 stamens. Female flowers have 2 totally concrescent, three-lobed bracteoles which enclose the ovary, a perianth is missing.
|
|
There are six papery perianth segments, with the inner shorter than the outer. The anthers are oblong and apiculate and the ovaries are rudimentary. The female spikelets may be single or several. They are borne in spicate cymes subtended by a persistent spathe.
|
|
Spikelets within the inflorescence (flower cluster) are generally arranged on spicate racemes in pairs. A fertile, unstalked spikelet is subtended by a sterile, stalked spikelet. In species where awns are present they are found on the fertile, unstalked spikelet as an extension of the lemma.
|
|
The leaves are trifoliate. leaflets are papery, with a glabrous upper surface. Inflorescences are densely spicate-racemose or paniculate, and bracts are foliaceous or dry, persistent or deciduous. Pods are small and turn brown when ripening; they are dehiscent, generally with two shiny black seeds in the vessel.

Carex tricephala is a species in the genus Carex, family Cyperaceae. It is one of only about seven species in Carex sect. Scabrellae. Members of this section have leaf-like bracts, and small spicate inflorescences. Carex tricephala is native to Southeast Asia, reported from Cambodia, Indonesia, Laos, Myanmar, Thailand, Vietnam and the Chinese province of Yunnan.

Cyperus scariosus is a perennial slender herb, stem at base nodosely thickened and suddenly constricted into a wiry rhizome, sub solitary, triquetrous at top. Leaves long, often overlapping stem. Flowers borne in compound umbel, spikes loosely spicate of 3-8 spixelets. Seeds in the form of trigonous nuts, flowers and fruits almost throughout the year, but chiefly during rainy season.
|
|
The inflorescences consist of axillary or terminal spikes or spicate panicles, or axillary clusters of glomeruled flowers. The flowers are unisexual, some species are monoecious, others dioecious. Male flowers consist of 3-5 perianth lobes and 3-5 stamens. Female flowers are usually lacking a perianth, but are enclosed by 2 foliaceous bracteoles, and contain an ovary with a short style and 2 stigmas.

Because its height is about that of a human's shin, and because it has sharp, spiny leaves, this species has been given the common name "shindagger". The leaf rosettes are monocarpic. Its pale to bright yellow flowers are held on branches onto the stem. The flowers are spicate inflorescences, tubular in shape, and about 8 mm by 4 mm (0.31 in by 0.16 in) in size.
|
|
The inflorescence usually emerges within the leaf crown but emerges below in those with rudimentary crownshafts. Branched or spicate, it contains male and female flowers, both with three sepals and three petals. Of the bees, wasps, ants and flies observed visiting the male flowers, only the ants were also consistent visitors to the female flowers. The fruit may be spherical or egg-shaped, bilobed, spindle-shaped, or flat and five- pointed.

After flowering linear, straight seed pods form that resemble a string of beads. The chartaceous, pubescent pods dry to a brown colour and are in length. The brown seeds found within the pods are arranged longitudinally and have a length of . Acacia arafurica is distinguished from A. sublanata by its thicker and larger phyllodes, its longer peduncles, and its inflorescences arranged in the form of a spike (spicate).

Buddleja yunnanensis is a small to medium shrub, 0.5-4 m tall with 4-angled branchlets, pubescent at first, becoming glabrescent. Leaves are oppsite and the blade elliptic to narrowly ovate,up to 12 X 4.5 cm, with tomentose undersides and glabrous above. Inflorescences terminal and small, relatively few flowers, densely spicate, only up to 6 cm long. Corolla lilac, with the tube 9 mm long, the outside with dense stellate hairs.

Xerocladia is most closely related to Prosopis (Melissa A. Luckow, personal communication, March 29, 2013 ). They both have stipular spines, leaves with few pairs of pinnae, and 10 stamens. In contrast to Xerocladia, Prosopis usually has a spicate inflorescence instead of a capitulum, an elongate straight or spiral legume pod which is not winged. Prosopis also has more (18-30) leaflets per rachilla, and leaflets opposite or sub opposite rather than alternate.

The lowest basal leaf sheaths are densely hairy, or very rarely smooth. The leaf blades are typically 5–60 cm long, 2–14 mm wide and may be either hairy or smooth. Each inflorescence typically has six or seven spicate branches, each of which carries numerous florets. These spikelets are usually 2–4 mm long, where the lower glume is as long as the spikelet and the upper glumes are where the lemma is situated (covered with 1 mm long hairs).

Calycadenia spicata is a species of flowering plant in the daisy family known by the common name spiked western rosinweed. It is endemic to central California, where is a common grassland plant in the Central Valley and adjacent Sierra Nevada foothills from Butte County to Kern County.Calflora taxon report, University of California, Calycadenia spicata (E. Greene) E. Greene, spicate calycadenia, spiked western rosinweed Calycadenia spicata is an annual herb producing a hairy, glandular stem 20 to 60 centimeters (8-24 inches) tall.

Buddleja cuspidata is a shrub 3-4 m in height, with brown tomentose branchlets, obscurely quadrangular. The opposite, thinly - coriaceous leaves blades are ovate or elliptic, 9-20 cm long by 4-9 cm wide, acuminate at the apex, decurrent into the petiole, sparsely pubescent above, brown tomentose beneath; the margins serrate - dentate to crenate - dentate. The narrow yellow inflorescences are axillary and spicate, 3-15 cm long by 1-1.5 cm wide; the corollas 7.5-8.5 mm long. Buddleja cuspidata is considered closely allied to B. axillaris and B. sphaerocalyx.

Flowers. Short stemmed, usually unbranched, stoloniferous herb to 10-30 cm high, forming extensive dense carpets, leaves equitant, roots bright orange-red, some plants forming dwarf shrublets to 50 cm high on grey more or less erect stems. Leaves bright to dark green and shiny above concolorous, paler and dull beneath, polymorph, sessile, short and long petiolate leaves even on the same plant, lanceolate, smooth thin coriaceous, lamina to 15 cm long and 4 cm wide, leaf tip descending, gradually tapering into c. 1 cm mucro acuminate to caudate, mucro to 1 cm long, base cuneate. Pseudopetiole green, caniculate when short petiolate, furrowed on the upper side when long petiolate, gradually extend into a short sheathing base, clasping the stem for distinctly more than its circumference. Inflorescence smooth, green below towards purple near the top, terminal, erect, spicate, to 30 cm long, bracts, 2-4, lanceolate ligulate, green with purple base, to 50 mm × 4 mm, early caducous, distally decreasing in size, flowers clustered 5-7 cm near the top the spike.
