Mr. Ch. C. Babington on some species of Cuscuta. 3 



more than one species included under the name of C. Epithymum, 

 My plant inhabits heathy places, growing upon Erica j blex, Sa- 

 rothamnus, &c. 



2. C. Trifolii (Bab.) ; fiorum glomerulis bracteatis sessilibus, calyce 

 infundibuliformi tubum corollae subsequante : segmentis lanceolatis, 

 interstitiis coroncc saccatis : lobis dimidium tuhi infundibuliformis 

 corollce suhaquantibus apice rotundatis fimbriatis convergentibus 

 hasi distantibus, stigniatibus filiformibus, (Plate I. fig, 3.) 



C. Trifolii, Bab. in Phytol. (Feb. 1843), i. 467 ; Ann. Nat. Hist. xiii. 

 252; Eng. Bot. Suppl. ined. t. 2898. 



C. Epithymum, /3. trifolii, Bab. Man. Brit. Bot. 302. 



C. minor, /3. Trifolii, Choisy in DcCand. Prod. ix. 453. 



Calyx funnel-shaped, rather thick, about as long as the tube of 

 the corolla, cream-coloured, but occasionally tinged with red ; 

 segments lanceolate, about as long as their tube. Tube of the 

 corolla rather irregularly funnel-shaped, about equal in length 

 to the lanceolate-attenuate spreading segments of the limb. An- 

 thers cordate-ovate with a minute apiculus. Corona with saccate 

 interstices below ; its processes about half as long as the tube of 

 the coi'olla, narrow, rounded, fimbriated and converging at the 

 end, narrowed below, separated from each other by broad inter- 

 spaces rounded at the bottom. Between each process the mem- 

 brane projects towards the centre of the flower so as to form a 

 cup-like space between it and the corolla. Germen truncate, nar- 

 rowed below, elevated upon a longish stalk. Styles iilifoi'm, 

 seated upon small sunken tubercles. Stigmas simple. 



A comparison of the above description and character with those 

 which precede them will, I think, prove conclusively that C. Tri- 

 folii is a really distinct species from C. Epithymum. It can 

 scarcely be necessary to call attention to the saccate corona and 

 the difference in the proportions and shape of the other parts of 

 the flower. 



The natural place for this plant is upon clover [Trifolium pra- 

 tense) J but it can live upon many other herbaceous plants. 



3. C. approwimata (Bab.) ; florum glomerulis bracteatis sessilibus, 

 calyce campanulato carnoso quam tubum corollse paulo breviori : 

 segmentis latis truncatis apiculatisque vel rhomboidalibus, corona 

 adpressa : lobis latis adpressis tubo corollce cylindrico paululum bre- 

 vioribus bifidis segmentis diver gentibus apice fimbria tis basi approxi- 

 matis, stigmatibus filiformibus. (Plate I. fig. 1.) 

 C. approximata, Bab. in Ann. Nat, Hist. (April 1844), xiii. 253. 



Calyx bell-shaped, fleshy, rather shorter than the tube of the 

 corolla, green, tinged with purple at the edge ; segments broad, 

 transverse, truncate and apiculate or rhomboidal, usually shorter 

 than their tube. Tube of the corolla cylindrical, longer than the
