Stace 4:
C. x luteus Lam. (C. x stellaris Haw., C. angustifolius Weston x C. flavus Weston) - Yellow Crocus.
Corm-covering becoming fibrous; leaves mostly 1-4mm wide; perianth bright yellow more or less uniformly or with brownish suffusion or stripes outside and on tube, with yellow, glabrous or hairy throat; (2n=10, 14). Neophyte-naturalised; much grown in gardens, naturalised as for C. neapolitanus; throughout Britain North to East Sutherland, Isle of Man, County Londonderry, County Wexford; garden origin. Many garden and most or perhaps all naturalised plants (to which description refers) are apparently this hybrid; the commonest garden plant (C. 'Dutch Yellow') are of this parentage. Whether pure C. flavus (2n=8) or C. angustifolius (2n=12) occur in the wild in British Isles is uncertain.
Key:
- Corm with covering splitting vertically, not horizontally, becoming fibrous or reticulated; ground colour of flowers yellow to deep yellow
- Perianth-lobes suffused or striped purplish-brown on outside, or if uniformly yellow then leaves 1-4mm wide
