Subtribe 2. PECTIDANAE. Heads radiate, rarely discoid. Involucre 
without calyculum; bracts in a single series, usually glandular-dotted, usually 
carinate at least at the base. Disk-corollas with a short tube, gradually 
passing into the elongate-funnelform or rarely trumpet-shaped throat. Leaves 
simple, sessile, often more or less clasping, in all (except in one species of Pectis 
and in Hydropectis) bristly-ciliate at least towards the base, the bristles rarely 
being inserted at the ends of small teeth. Style-branches of the hermaphrodite 
flowers short, oblong, obtuse. 
Heads radiate; achenes linear; leaves usually conspicuously glandular-dotted; 
land-plants. 21. PEcTIS. 
Heads discoid; achenes elongate-clavate, tapering downwards into a stipe-like 
base; leaves sparingly if at all glandular-dotted; water-plants. 22. HypROPECTIS.

Rather low, branching, mostly aromatic or strong-scented, annual or perennial herbs. 
Leaves opposite, glandular-dotted, mostly entire, usually with several pairs of marginal 
bristles near the base, or rarely along the whole margins. Heads usually small, solitary or 
cymose, radiate. Involucre from cylindric or oblong to campanulate or turbinate; bracts 
3-12, free, in a single series, without calyculum, usually glandular-dotted, rounded-carinate 
at least below, usually gibbous at the base, and partly surrounding the ray-achenes. Re- 
ceptacle naked. Ray-flowers few, pistillate and fertile, usually of the same number as the 
bracts; ligules yellow or tinged with red or purple. Disk-flowers rather few, hermaphrodite 
and fertile; corollas yellow; tube usually short, gradually passing into the narrowly funnel- 
form or trumpet-shaped throat; limb 5-lobed, often somewhat bilabiate. Anthers entire and 
obtuse at the base. Style hispidulous, the short branches obtuse and without appendages. 
Achenes linear, terete or somewhat angled, pubescent or glabrate. Pappus various, of few or 
many squamellae, awns, or bristles, or rarely reduced to a mere crown. 
Type species, Pectis ciliaris L.
