NOTES ON THE FLORA OF CEYLON. 241 



cytinoides Wight in the 'Fl. Brit. India,' but this is very distinct 

 from the plant above described. It is not infrequent in the high 

 mountainous forests here, growing on the roots of Strohilanthes, and 

 I have had several opportunities of examining fresh specimens. I 

 am inclined to think Wight's genus a good one, and its reunion 

 with Christisonia by Sir J. Hooker to be uncalled for. The structure 

 of the anthers is very different in CamphelUa; they are strictly one- 

 celled, open by a terminal pore, and are quite free from one another 

 and without spores ; the style, too, is different, being hooked, 

 ovoid, and quite entire. The genera are, however, closely allied, 

 and their station away from one another in different natural orders, 

 as in the ' Gen. Plant.,'* is as clearly an extreme in the opposite 

 dh-ection. The structure of the ovary and placentas is quite the 

 same in both genera, truly one-celled in all I have examined, 

 except occasionally near the base. 



C. ThwaitesU, from its ebracteolate pedicels and large fleshy 

 placentas, is referable to Wight's genus OligophoUs, which is 

 generally regarded as not distinct from Christisonia ; but this also 

 requires further examination of fi'esh specimens, which I hope 

 I may get the opportunity of making. 



Christisonia bicolor Gardn., var. spectabilis. — C. spectabilis Thw. 

 ms, — Differs from var. ■pallidijiora Thw. (C. pallida Gardn.) in its 

 much larger size, the flowers reaching 3 in. in length, with a more 

 spreading limb, which is pure white, the tube being yellow and the 

 calyx pink ; the rhizome is much stouter. 



Hab. The Eaiuckles Hill, Kallebokka Vallev, Central Prov., 

 Sept. 1868. (C. P. 3983 in Herb. Perad.). A very beautiful 

 variety of this variable species, connected with the type through 

 forms of pallidi/lora. 



Scutellaria spicata Trim. — Stem stout, erect, densely covered 

 with short deflexed hairs ; leaves ovate or ovate-oblong, on hairy 

 petioles, cordate or subcordate at base, obtuse at apex, strongly 

 crenate, nearly glabrous above, densely velvety-hairy on the 

 prominent veins beneath ; flowers few, very shortly stalked or 

 subsessile, forming a terminal erect unbranched spicate inflorescence 

 3-4 in. long ; bracts broadly oval, longer than the pedicel, all 

 densely hairy, with spreading hairs; calyx longer than in other 

 Ceylon species, strongly pilose ; corolla very large, the tube wide, 

 hairy without, the segments very wide. 



Hab. By streams on Adam's Peak, at about 5500 ft. elevation, 

 March, 1883. This may perhaps be no more than a variety of the 

 common and variable ;S'. violacea ; but the very large wide -tubed 

 coralla (over ^ in. in length), large bracts and nearly sessile flowers 

 give it a very distinct look, and may be sufficient for specific 

 separation. I have not seen a specimen of S. robnsta Beuth. (DC. 

 Prod. xii. p. 418), also from Ceylon, which, from the description, 

 must come very near ; and is placed by Thwaites (Enum. p. 232j 

 under S. violacea. 



* Christisonia alhida Thw., referred to Cavipbellia in 'Gen. Plant.' ii. p. 967, 

 is rightly put back again into Christisonia in the 'Fl. Brit. India.'
