Whole plant yellow. Stem 3-6 in. long, thick, obtusely angled. Scales in. 

 Flowers 8-12 ; pedicels -f in., angular, thick ; bracteoles below the middle about 

 | in. long, acute, veined, toothed at the tip. Calyx f in. long. Corolla 1 in. long, 

 funnel-shaped ; lobes rounded, quite entire. Placentas in Wight's drawing of 

 Campb. cytinoides nearly meeting in the axis of the ovary, the flat opposed faces with- 

 out ovules. Gardner described C. unicolor from a drawing of which I have seen no 

 copy. Except in the subexserted anthers and obtusely 5-lobed calyx, I do not see how 

 it differs by his description from C. neilgherrica. A drawing sent by Thwaites of 

 the plant he refers to C. unicolor has acute calyx-teeth. In Wight's Campb. 

 aurantiaca (referred here by Clarke) the corolla is represented as hairy on both 

 surfaces, as are the filament and style ; and the anthers are exserted ovate acute, and 

 2-celled. In his Campb. cytinoides the anthers are also exserted ovate and acute, but 

 1-celled. I find the corolla in Wight's specimens to be either perfectly glabrous or 

 pubescent, and the anthers to be ovoid acute 1-celled. 



8. C. tricolor, Gardn. in Cole. Journ. Nat. Hist. viii. 153; quite 

 glabrous, stem slender few-fld., scales few ovate acute, calyx 5-angled 

 narrow, lobes acute, corolla with the upper lip blood-red, lower rose- 

 coloured, throat yellow, filaments glabrous. Thwaites JSnum. 222. 



CEYLON; Central Province, alt. 3-4000 ft.,parasitical on Acanthacece, Gardner, &c. 



Stems more slender than in any of the preceding, 2-4 in. high. Scales about | in. 

 Calyx | in. long. Corolla 2| in. long, lobes denticulate. Stigma with the large lobe 

 orbicular. Placentas 2 -partite, cordate in section, covered all over with ovules. A 

 coloured figure apparently of this species in Jerdon's collection of drawings represents 

 the corolla as 3 in. long, with a violet upper lip, and pale rose lower one ; the calyx 

 pedicels and bracts are red-brown. 



VAR. grandijlora ; corolla larger pale rose-coloured. C. grandiflora, Gardn. I. c. 

 155; Thwaites I.e. 221. Ceylon; Adam's Peak, alt. 5000 ft., Gardner. Gardner 

 gives no other characters but greater size and a uniform rose colour of the flower, 

 whereby to distinguish this from C. tricolor; for that of the sterile cell of the 

 anther being ascending (and not deflexed) is, as Thwaites' (who suggests grandiflora 

 being a variety), a fallacious one. 



9. C. albida, Thwaites mss. ; sparsely pubescent, stem very short, scales 

 very obtuse, flowers crowded very shortly pedicelled, calyx 2-bracteolate, 

 lobes rounded, filaments very short, anthers all unequally 2-celled, cells 

 oblong parallel. Campbellia albida, Benth. in Gen. PI. ii. 967. 



CEYLON ; near Hankalla, alt. 6000 ft., Thivaites. 



Stem 1-2 in., from an elongate warted rhizoma like that of C. bicolor, very stout. 

 Scales i in., obovate, tip rounded. Flowers crowded, much smaller than in any of 

 the other species. Calyx % in. long, pubescent, lobes very short, erose. Corolla 

 1 in., pubescent externally. Anther-cells acute below. Ovary completely 2-celled ; 

 stigma very small, clavate.
