Botanical name:Digera muricataFamily:Amaranthaceae (Amaranth family)
Synonyms: Achyranthes alternifolia, Chamissoa muricata, Digera arvensis

False Amaranth is an annual herb, growing to 20-70 cm tall. It can be seen growing wild in waste areas. Stems are simple or branched from the base, nearly hairless. Alternately arranged leaves, 1-9 cm long and 0.2-5 cm broad, are narrowly linear to broadly ovate. Leaf stalks are long, up to 5 cm, base is narrowed, and the tip pointed. Flowers are borne on slender spike-like racemes, which can be as large as 30 cm long. The racemes are on a stalk that can be up to 14 cm long. Flowers are hairless, white mixed with pink to carmine or red, usually becoming greenish-white in fruit. Fruit subglobose, slightly compressed, 2-2.5 mm, bluntly ribbed along each side, surmounted by a thick rim. In India, the young leaves and shoots of False Amaranth are made into curries, or the entire plant is boiled and seasoned. Flowering: August-September.

Abstract

Weeds are considered as a source of new viruses and reservoirs of economically important viruses but are often neglected during diversity studies. Here, we report the complete nucleotide sequences and phylogenetic analyses of the components of a begomovirus disease complex associated with yellow vein disease of Digera arvensis. a common weed. The begomovirus associated with the disease showed 98% nucleotide sequence identity with Cotton leaf curl Rajasthan virus. Two species of betasatellite were identified. The first betasatellite species was an isolate of Ageratum yellow leaf curl betasatellite. The second was a recombinant consisting for the most part of sequence derived from a Tobacco leaf curl betasatellite but with the satellite conserved region (SCR) and some sequence between the SCR and adenine-rich (A-rich) region derived from a Cotton leaf curl Multan betasatellite. The alphasatellite isolated from this weed was near identical to an isolate recently characterized from potato. The presence of multiple and recombinant betasatellites in D. arvensis indicates that weeds can be important sources of multiple begomovirus components that affect crop plants. Furthermore, the presence of a recombinant betasatellite suggested that weeds are likely vessels for recombination and evolution of components of begomovirus complexes.

Style 1.5–4 mm, the stigmas finally recurved. Lateral flowers much reduced (more so upwards and sometimes only single fertile flowers present in the upper part of the spike), modified into antler-shaped scales, the lateral lobes narrow to broad and wing-like in fruit. Fruit subglobose, ± verrucose, crowned by a thick circular rim or corona of short firm processes.

This grows as wild
AMARANTHACEAE-CHENOPODIACEAE WEEK: Digera muricata is a lone species worldwide in Digera genus (Amaranthaceae ). It occurs as a common weed, up to 50cm tall, with wheat here in Pantnagar.

As you have described it is a lone species from the genus Digera. Occurs as a weed all over the world. I read from the key:
It comes under the major group having alternate leaves. Next.
Fertile flowers subtended by sterile modified flowers which is not the case with other genera in this group. Can you elaborate on this? Is it visible in your pictures?
I may be able to learn something.

Help ID of following herb, photographed on 11July13.

Digera muricata. Amaranthaceae.

Kindly identify this weed found growing in an agricultural field near Tiruvanamalai, Tamil Nadu. Photographed end Jan 2014.

plant in the habit photo possibly a younger plant about 20 cm in height. older plants had much longer branches ending in inflorescences, as much as 30-40 cm. Digeria muricata of Amaranthaceae. is correct

an edible weed. thank you all for the identification.

Veronica arvensis page


Veronica arvensis L. - Corn Speedwell

Stems - Erect, decumbent, or sprawling, multiple from fibrous roots, to +/-15cm tall, herbaceous, hollow, villous.

Leaves - Opposite, petiolate below, sessile above, broadly ovate to triangular above, to +/-1cm long, 1cm broad, crenate-serrate, pubescent.

Inflorescence - Terminal bracteate raceme to +/-5cm long. Bracts foliaceous and giving the flowers a single axillary look. Flowers sessile or on petioles to -1mm long.

Flowers - Corolla deep blue-purple, to 5mm broad. Petals 4, united at the base to form a short tube to .5mm long. Lobes of the corolla rounded. Stamens 2, erect, adnate at the base of the corolla tube. Filaments whitish, glabrous, to 1mm long. Anthers bluish and white. 3-.4mm long. Ovary superior, green, orbicular, compressed, pubescent on the margins. 5mm in diameter. Style whitish-green, -1mm long and glabrous. Calyx accrescent, deeply 4-lobed, glandular and simple hispid. Lobes oblong, typically unequal, green, rounded to subacute, to 2mm in flower (much longer in fruit). Calyx tube short, -1mm long.

Flowering - March - August.

Habitat - Open rocky woods, glades, waste ground, cultivated areas, fields, pastures, lawns, roadsides, railroads.

Origin - Native to Europe.

Other info. - This little introduced species can be found throughout Missouri. This is one of the earliest little plants to bloom in the spring. The earliest flowers tend to be smaller than the flowers that come later in the season. This is an easy species to ID in the field because of the small blue flowers, sessile leaves, and pubescent stems.
