389 



or somewhat urn-shaped to short-tubular, with 5 usually spreading 

 lobes imbricated in the bud, and as many small scales or appendages 

 inserted in the tube below the stamens, or none. Ovary globular, 

 2-celled, 4-ovuled. Styles in ours distinct, persistent. Stigma glo- 

 bose. Capsule 1 to 4-seeded, ours indehiscent. The embryo is devoid 

 of cotyledons. The seed germinates on the ground and the twining 

 stems become parasitic by means of suckers which penetrate the bark 

 of the host. (Derivation doubtful.) 



Capsule pointed or conical; corolla-tube with fimbriate scales. 



Corolla-lobes % as long as the cylindrical tube 1. C. subinclusa. 



Corolla-lobes as long as the shallow-campanulate tube . . 2. C. saliiui. 

 Capsule depressed-gbobose. 



Flowers in dense globose clusters; scales present 3. C. arvensis. 



Flowers in loose cymes; scales none 4. C. Californica. 



1. C. subinclusa Dur. & Hilg. Stems commonly stout; flowers 

 1\ to 3 lines long, sessile or short-pediceled. at length in large dense 

 clusters \ to \\ in. thick; calyx-lobes overlapping, ovate-lanceolate, 

 about \ the length of the cylindrical corolla-tube; lobes of the corolla 

 ovate-lanceolate, minutely crenulate, scarcely more than \ the length 

 of the tube; anthers oblong or oval, nearly sessile; scales narrow, 

 fimbriate, opposite the stamens but reaching only to the middle of tin- 

 tube; styles slender, mostly longer than the ovary; ovary capped by 

 the withered corolla. 



Very common on Poison Oak and other shrubs and herbs, often 

 occurring on Salix and making thick tangles 1 to 2 ft. across. Calyx 

 sometimes reddish; lobes of the corolla mostly erect; tube sometimes 

 narrowed above. 



2. C. salina Engelm. Marsh Dodder. Stems slender; flowers 

 1£ lines long; calyx-lobes ovate-lanceolate, as long as the shallow- 

 campanulate tube of the corolla and as the corolla-lobes; these ovate, 

 denticulate, overlapping; filaments about as long as the oval anthers; 

 scales fringed, mostly shorter than the tube, sometimes much reduced 

 and on the base of the tube; styles equaling or shorter than the ovary; 

 capsule surrounded by the withered corolla, mostly 1-seeded. 



Very abundant on Salicornia and other saline herbs, entangling 

 them with its webs of thread-like stems, which in spring color the 

 salt marshes with small patches of golden color. Flowering July- 

 Sept 



3. C. arvensis Bey rich. Stems pale; flowers in dense globose 

 clusters h in. thick; calyx-lobes obtuse, broad; corolla 1 line long, 

 with acuminate lobes and short and broad tube, in age remaining at 

 base of capsule; scales deeply fringed. 



Alvarado Marshes, on Xanthium. 



4. C. Californica Choisy. Stems capillary; flowers small. 1 to U 

 lines long, in loose cymes; pedicels frequently much thickened below 

 the flower; calyx-lobes with short-attenuate spreading tips; corolla- 

 lobes lanceolate-subulate, equaling or longer than the campanulas 

 tube, mostly reflexed in anthesis"; scales none, sometimes repre- 

 sented by inverted arches or V-shaped thickenings alternating with
