Family Orobanchaceae

Herbs annual , biennial, or perennial parasites, without chlorophyll. Stems unbranched or sometimes branched. Leaves scalelike, spirally or subimbricately arranged. Inflorescences racemose, spicate , or subcapitate , rarely 1-flowered; bract 1, usually similar to leaves; bractlets 2, adnate to base of calyx or pedicel. Flowers bisexual , subsessile or pedicelled. Calyx tubular, cupular, or campanulate , (3 or) 4-6-lobed, 2-6-parted, 6-toothed, or spathelike, sometimes absent or of 3 free sepals. Corolla bilabiate, usually curved , sometimes tubular-campanulate or funnelform with 5 subequal lobes ; upper lip entire, emarginate , or 2-lobed; lower lip 3-lobed. Stamens 4, didynamous , inserted at base of corolla tube ; filaments slender; anthers 2-celled, dehiscing longitudinally, sometimes 1 cell fertile and another sterile or reduced to spur. Pistil 2- or 3-carpellate; ovary superior; placentas 2-4 or 6(-10), parietal or sometimes axile at ovary base; ovules 2-4 or numerous , anatropous . Style long; stigma inflated , discoid , peltate, or 2-4-lobed. Capsule usually dehiscing loculicidally by 2 or 3(or 4) valves . Seeds minute, testa pitted or reticulate .

About 15 genera and 150 species: North Temperate regions , less represented in Africa, America, Asia, and Australia; nine genera and 42 species (nine endemic) in China.[1]

Genus Pedicularis

Herbs perennial or annual , rarely biennial, hemiparasitic. Leaves alternate, opposite, or whorled , usually pinnatifid to 1- or 2-pinnatisect, rarely entire or dentate . Lower leaves usually long petiolate ; upper leaves often ± sessile. Inflorescences terminal or flowers axillary ; bracts usually leaflike. Calyx tubular to campanulate , often ± bilabiate, usually deeply cleft anteriorly, (2--) 5-lobed. Corolla purple, red, yellow, or white, strongly bilabiate; upper lip (galea) hooded , enclosing anthers , laterally compressed , rounded or truncate , or terminating in teeth or in a beak ; lower lip 3-lobed, usually spreading , external to upper lip in bud. Stamens 4, didynamous ; filaments glabrous or pubescent ; anthers mucronate or not. Stigma capitate. Capsule moderately compressed or not, loculicidal. Seeds numerous , reticulate or costate .

About 600 species: best represented in the mountains of SW China and widespread in the frigid and alpine zones of the northern hemisphere; 352 species (271 endemic) occur in China.

From the limited available data, the species of Pedicularis in China are pollinated by bumblebees gathering nectar and/or pollen on nectariferous non-beaked species, and pollen only, by scraping or vibrating,on beaked species including those with long corolla tubes (Macior, L. W. 1988. Plant Species Biol. 3: 61--66.; Macior, L. W. & S. K . Sood. 1991. Plant Species Biol. 6: 75--81.; Macior, L. W., pers. comm. ).

The rank of series has been traditionally used in Pedicularis since the time of Prain's work (Ann. Bot. Gard. (Calcutta) 3: 1--196. 1890). Sections (and subgenera ) have also been used (e.g. , by Bunge in Walpers, Repert. Bot. Syst. 3: 409--433. 1844; Li, H. L. Proc. Acad. Nat. Sci. Philadelphia 101: 1--214. 1949; Yamazaki, T. 1988. A revision of the genus Pedicularis in Nepal. in: Ohba, H. & Malla, S.B. (eds.), The Himalayan Plants 1: 91--161, and others). [2]
