Pl. Aegypt. 23–24 ( October 1840) [basionym].   Description. A holoparasitic (achlorophyllous), glabrous herb, with a stout stem, swollen at the base. Plant robust, 30–130 cm, stem dirty-white or grey, 15–40 mmin diameter. Lower scales dense, constricted, entire, triangular, yellowish-white, grey or dark grey, 5–10 × 5–10 mm. Middle and upper scales and floral bracts triangular-lanceolate, entire, scarious and variably, often markedly serrate along the margins, dirty-white to grey, 7–15 × 15–30 mm. Inflorescence a dense, many-flowered spike, 20–100 cmlong, 4–15 cmin diameter. Floral bracts about as long as calyx or somewhat longer. Floral bracteoles 2, linear or lanceolate, obtuse, 2–6 × 10–20 mm, white to grey, scarious and serrate along the margin, attached to the calyx base and equal or slightly shorter than calyx. Calyx tubular-campanulate, dirty-white to grey, 10–22 mm. Calyx lobes 5, equal or subequal with one slightly shorter lobe, oblong-rounded, entire, scarious and serrate at the margin. The upper lobe shorter than the rest by up to 3 mm. Corolla infundibuliform, pentamerous, 35–45 mm. Corolla tube bright yellow, with two shallow, yellow folds inside. Corolla tube arched beneath the middle. Inner tube more or less short-pubescent around the filament bases and glabrous elsewhere. Limb usually bright yellow, sometimes slightly tinged crimson (especially conspicuous in bud), 15–30 mmin diameter. Corolla lobes 5, rounded, equal or the upper ones slightly smaller than the other 3, usually wider than long. Stamens 4, inserted at the base of the tube, included. Filaments 20–25 mm, densely pubescent at the base and weakly, very short-pubescent or glabrous above. Anthers 3 × 5 mm, densely lanuginose, rounded-elliptic to apiculate. Ovary ovate, 4–5 × 10–12 mm, white or yellowish-white with a yellow ring at base, dark brown when dry. Capsules ovoid-globose, 12–20 × 15–20 mm, dehiscent with 2 (- 3–4) valves. Fl. January-April.   Habitat and prevalence. Wadis in the desert. Along the Rift Valley from the southern JordanRiver to Eilat, in the eastern and southern Judean desert, and the central and southern Negev desert. Fairly common in its habitat.    Host. Mostly  Tamarixssp. from  T. nilotica(Erenb.) Bunge.group and  Atriplex halimusL. Probablyother desert shrubs, especially in the Amaranthaceae.   Notes. see  C. tinctoria.  C. tubulosacan be found in mixed populations with either  C. laxifloraor  C. violacea, and there is evidence of hybridization with the latter.   Specimens examined.   Israel• (Palestine), Lower Jordan Valley, plain of Jerico,  27.
