Abstract: Subgenus Pseudolysimachium.Pubescent perennial herb.Shallow roots, white, ®ne and ®brous.Taproots 1.5 mm diameter, light brown, sparsely branched, but roots mostly adventitious, often into cracks and crevices of fragmented rocks.Rhizomes/ stolons somewhat woody, shortly creeping and rooted or long and thick, less than 10 cm deep, arising above or below ground level.Stock shortly creeping, hard, almost woody.Stems erect, woody near base, ascending or spreading, e.g.near scrub edge or at cli edges hanging down before ascending at or in the spike.Stems to 30 cm in ssp.spicata [in ssp.hybrida 60±85(À100) cm], stout, more or less densely hairy and glandular, rarely glabrous.Leaves decussate, 15±80 Â 2±30 mm, lower ovate or oval crenate, sometimes doubly crenate, becoming linearlanceolate, crenate-serrate or upper leaves sometimes entire or sessile.Petioles 0±30 mm.Lowest leaves of ssp.spicata 15±30 Â 8±12 mm, crenate-serrate only at widest part (nearly middle), gradually narrowed into petiole; in ssp.hybrida lowest leaves 20±40 Â 10±20 mm, usually crenate-serrate along most of the margin, widest below the middle and abruptly narrowed into the petiole.In¯orescence a many-¯owered terminal spike-like raceme.Mostly single, occasionally with up to 10 or more lateral in¯orescences in ssp.hybrida, usually smaller than main in¯orescence, arising from axils of stem leaves; rarely the spike itself splits.Pedicels very short, 0.5 mm.Bracts 1±3 Â 1±1.5 mm, broadly lanceolate, one per ¯ower.Sepals 4, occasionally 5, 1±2.5 Â 2±6 mm, lanceolate to triangular acute, glandular hairy, plus *Abbreviated references are used for standard works; see Journal of Ecology (1975), 63, 335±344.Nomenclature of vascular plants follows Flora Europaea and Stace (1997) and for British species.
