Description
Slender erect perennial, sometimes climbing or scrambling. The leaves are often covered in silvery indumentum when young (less noticeable in shade growing specimens) Inflorescences dense at first but elongating up to 25 cm with more widely spaced flowers. Flowers greenish to silvey-white, often tinged with purple-red. Click here to view the original data object Citation:Hyde, M.A., Wursten, B.T. and Ballings, P. (2002-2012).

Stout perennial herb. Var. pubescens is a more robust plant with larger and more colourful flowers than var. sicula, a slender scrambling herb with silvery undersides to the undersurface of the young leaves.

Perennial herb (sometimes woody and somewhat suffrutescent), occasionally flowering in the first year, 0.2-2 m, stiffly erect to subscandent or straggling and ±prostrate, simple to much-branched, stems stout to very weak, distinctly to obscurely 4-angled, striate or sulcate, subglabrous to densely tomentose, the nodes ±shrunken when dry. Leaves elliptic, oblong or oval and acute or acuminate to almost round and very obtuse, gradually or abruptly narrowed below, (2-) 3-12 (-16) x 1.3-6 cm, indumentum varying from uniformly subglabrous through subglabrous above and densely appressed-canescent below to ± densely tomentose on both surfaces; petioles of main stem leaves 3-25 mm, shortening above and below. Inflorescences at first dense, finally elongating to (5-) 8-34 (-40) cm; peduncles (0.6-)1-6(-7.5) cm. Bracts lanceolate or narrowly deltoid-lanceolate, pale or brownish-membranous, 1.75-5 (-6) mm, glabrous. Bracteoles 1.5-4.5 (-6) mm, the basal wings 1/3-1/4 (-1/2) the length of the spine and adnate to it, typically tapering off above but not rarely rounded or truncate. Perianth whitish or pale green to red or purple, segments 5, 3-7 (-10) mm, the outer longest, narrowly lanceolate to lanceolate, very acute, with a distinct midrib and 2 obscure to distinct lateral nerves, narrowly or moderately pale-margined. Stamens 5, the filaments 1.5-4.5 (-6) mm, alternating with subquadrate pseudo-staminodes. Typically the apex of the latter curves slightly inwards as a narrow, crenate or entire, often very delicate flap, while from the dorsal surface arises a fimbriate-ciliate scale extending across the width of the pseudo-staminode; not rarely, however, this is reduced to a “stag’s-horn” process at the centre of the dorsal surface, or even becomes small and filiform-or else subapical or apical so that the pseudo-staminode appears simple (this mostly in small forms of var. sicula, which has not yet been found in Pakistan). Style slender, 1-4 (-6) mm. Capsule 1-3 (-5) mm. Seed filling the capsule, cylindrical, smooth.

Herbs perennial, 20-120 cm tall. Stem quadrangular, pubescent; nodes slightly inflated; branches opposite. Petiole 0.5-1.5 cm, somewhat hairy; leaf blade broadly obovate or elliptic-oblong, 1.5-7 × 0.4-4 mm, papery, both surfaces hairy, base cuneate or rounded, margin entire or undulate, apex obtuse, with a mucro. Spikes terminal, erect, reflexed after anthesis, 10-30 cm; rachis angular, stout, densely hairy. Bracts lanceolate, 3-4 mm, apex acuminate; bracteoles spiny, shiny, 2.5-4.5 mm, rigid, base 2-winged; wings 1.5-2 mm, membranous, margin entire. Tepals lanceolate, 3.5-5 mm, with a vein. Stamens 2.5-3.5 mm; pseudostaminodes truncate or crenate at apex, fimbriate and ciliate. Utricles ovoid, 2.5-3 mm. Seeds brown, ovoid, ca. 2 mm. Fl. Jun-Aug, fr. Oct. 2n = 42, 48, 84, 96.

Plants perennial or annual. Stems 0.4-2 m, pilose or puberulent. Leaf blades elliptic, ovate, or broadly ovate to orbiculate, obovate-orbiculate, or broadly rhombate, 1-20 × 2-6 cm, adpressed-pubescent abaxially and adaxially. Inflorescences to 30 cm; bracts mem-branous; bracteoles long-aristate, spinose; wings attached at sides and base. Flowers: tepals 4 or 5, length 3-7 mm; pseudostaminodes with margins fimbriate at apex, often with dorsal scale. Utricles ± cylindric, 2-4 mm, apex truncate or depressed.

How to identify this species

For a detailed description, refer to the General Morphology details above

If no maps are displayed below, it means the required data is absent. Click on "Edit with form" button on top of the page to add this information.

Pubmed Word cloud

This word cloud is obtained using the tool LigerCat by searching the Pubmed database. LigerCat builds the cloud from the most relevant Medical Subject Headings (MeSH) terms. Each term's relative size indicates how many times it appears in the PubMed search results. Click on a term to access the full LigerCat cloud, with live PubMed search capabilities. LigerCat has been developed for the Biology of Aging Project.

The page may take some time to load since LigerCat is searching the entire PubMed database and sending us the results in real time.

• If there is an error message below, it means that there is no retrievable information available on NCBI
  
• If the number of nucleotide sequences is less than 100, very little genomic work has been done on this species. A respectable number of nucleotide sequences is above 10000.
• Most of the nucleotide sequences may come from three sources:

1. Studies on single genes, where people try to sequence genes such as some specific dehydrogenases important,say, for tannin production
2. Sequences of Ribosomal Internal Transcribed Spacer, whose sequence is used for generating molecular phylogenetic trees to establish species relationships
3. Expressed Sequence Tags (ESTs) which can tell about which genes are present and expressed in the species at a particular time in the given tissue
