Description
Family Urticaceae
Herbs, subshrubs
, or shrubs
, rarely trees
, very rarely climbing
, stems often fibrous
, sometimes succulent. sometimes armed
with stinging
hairs
; epidermal cells
of leaves, sometimes stems, perianths mostly with prominent
cystoliths
punctiform
to linear
; Leaves alternate or opposite, stipules present, rarely absent; leaf blade
simple
. Inflorescences cymose
, paniculate
, racemose, spicate
, or cluster-capitate, usually formed from glomerules
, sometimes crowded on common enlarged cuplike or discoid
receptacle, rarely reduced into a single flower. Flowers unisexual
(plants
monoecious or dioecious), rarely bisexual
in partial flowers; actinomorphic
, very small, (1-) 4- or 5-merous, rarely perianth absent in female flowers. Calyx absent. Perianth lobes imbricate or valvate
. Male flowers: stamens as many as and opposite to perianth lobes, filaments
inflexed
in bud; anthers
2-locular, opening lengthwise, rudimentary
ovary often present. Female flowers: perianth lobes free
or connate
, usually enlarged in fruit and persistent
, occasionally absent; staminodes scarious
, opposite to the perianth lobes, or absent. Ovary rudimentary in male flowers, sessile or shortly stipitate
, free or adnate
to the perianth; 1-locular, ovule solitary, erect
from the base
; style simple, or absent; stigma diverse
, capitate, penicillate-capitate (brushlike), subulate
, filiform
, ligulate
, or peltate. Fruit usually a dry achene, sometimes a fleshy
drupe, often enclosed by the persistent perianth. Seed solitary, endosperm usually present; embryo straight; cotyledons ovate
elliptical
or orbicular
.
About 47 genera and 1300 species: most numerous
in wet tropical regions
, extending into temperate regions
; 25 genera and 341 species (163 endemic, one introduced
) in China.
Plants in this family
have numerous uses. The stem fiber of some genera and species is of high quality and used to make cloth, fishing nets
, and ropes and for some industrial materials
. In central and southern China,
Boehmeria nivea is widely cultivated for ramie fiber and Girardinia diversifolia subsp.
triloba is widely cultivated for red huo ma fiber. Boiled young shoots
of Girardinia, Laportea, and Urtica are eaten as vegetables. Some species are used in local Chinese medicine. Pellionia repens, Pilea cadierei, P. microphylla, and P. peperomioides, among other species, are widely cultivated as ornamentals
in China and elsewhere. Some genera, such as Elatostema, Pellionia, and Pilea, occur frequently in shady, moist habitats
of subtropical
forests
and become dominant elements
of the forest floor vegetation. Plants of the first five genera belong to tribe
Urticeae, which is usually characterized by the distinctive stinging hairs.[1]
Genus Urtica
Herbs, annual
or perennial
, with stinging
and nonstinging hairs
on same plant. Stems simple
or branched, erect
, ascending
, or sprawling
. Leaves opposite; stipules present. Leaf blades
elliptic
, lanceolate, ovate
, or orbiculate, margins
dentate
to serrate; cystoliths
rounded
or ± elongate
. Inflorescences axillary
, lax
, of cymes arranged in racemes
or panicles. Flowers unisexual
, staminate
and pistillate
flowers in loose
to tight clusters
in separate inflorescences or intermixed in same inflorescence on same or different plants
; bracts narrowly triangular to lanceolate, lacking hooked
hairs. Staminate flowers
: tepals 4, distinct
, equal; stamens 4; pistillode
cuplike. Pistillate flowers: tepals 4, distinct, inner 2 equal to achene, outer 2 smaller, without hooked hairs; staminodes absent; style absent; stigma tufted
, persistent
or deciduous. Achenes sessile, laterally compressed
, ovoid
or deltoid, loosely enclosed by inner tepals. x
= 12, 13.
Species 45: nearly worldwide.[2]
Physical Description
Species Urtica dioica
Herbs, perennial , rhizomatous , 5-30 dm. Stems simple or branched, erect or sprawling . Leaf blades elliptic , lanceolate, or narrowly to broadly ovate , 6-20 × 2-13 cm, base rounded to cordate, margins coarsely serrate, sometimes doubly serrate, apex acute or acuminate; cystoliths rounded. Inflorescences paniculate , pedunculate , elongate . Flowers unisexual , staminate and pistillate on same or different plants , staminate ascending, the pistillate lax or recurved. Pistillate flowers: outer tepals linear to narrowly spatulate or lanceolate, 0.8-1.2 mm, inner tepals ovate to broadly ovate, 1.4-1.8 × 1.1-1.3 mm. Achenes ovoid to broadly ovoid, 1-1.3(-1.4) × 0.7-0.9 mm. [source]
