Castilleja
(named in honour of D. Castillejo, a botanist of Cadiz). ORD. Scrophularineae. Herbaceous, rarely suffruticose plants. Flowers axillary, solitary or terminal, and spicate; corolla tubular, compressed, bilabiate. Leaves alternate, entire, trifid or multifid; bracts large and coloured. These are very ornamental plants, but, with one or two exceptions, are rarely seen in cultivation. All are probably more or less parasitic in habit, and this accounts for the difficulty generally experienced in preventing the plants from being altogether lost. All succeed in a peat soil, with a little leaf mould and sand, but some do better in good loam. Hardy and half hardy species may be increased by seeds.
