have no definite form; if any 1. are produced, they are very fugacious. 

 This is the most montane of our species. 



P. Gardtieri, Harv. in Thw. Enum. 223 (C. P. 2989) grows with 

 P. olivacetan at Ramboda and Pundalu-oya in Oct. and Nov. No 

 flowers have been seen, the whole plant consisting merely of a stout 

 simple cylindrical erect stem, \-\\ inch long, crowned with a tuft of very 

 numerous filiform green i-nerved leaves, red at the base. It is probably, 

 as Thwaites suggests, an early stage of P. oHvaceum^ or perhaps an 

 abnormal vondition. {Dicrcua apicata^ Tul., from the Nilgiris, seems to 

 be nearly the same, and is considered to be a state of P. dichotoniiis of 

 those mountains. It is well figured by Warming (1. c. vii. 4, ff. 18-25), 

 who also shows a 'thallus' (with flowers), but allows that he has never 

 been able to trace an actual connexion between this and the tufts, though 

 the latter are always found alongside it.) 



5. P. metzgrerioides, Trim. n. sp. [Plate LXXVI.] 

 Frond creeping, flat, ribbon-like, adpressed to surface of 

 subjacent rock, about ^^ in. wide, rather zigzag, dichotomously 

 branched, hard-fleshy, bright light green ; 1. few, \-\ in., linear- 

 spathulate, obtuse, very delicate, in little tufts of 2-4 at edge 

 of frond; fl. sessile, distant, bracts 3 or 4 thick, obtuse, spathe 

 curved irregularly, lobed at mouth, enclosing ov. ; stam. i, fil. 

 very long, 3 times length of ov., much exserted beyond spathe, 

 thick, flat, anth. triangular, cells divergent at base, staminodes 

 as long as ov. very slender ; ov. nearly globose, styles linear, 

 long, exserted, spreading; fruit not seen. 



On rocks in rivers, at present found only at Hakinda on the Mahaweli 

 below Peradeniya, where it was first collected in 1891 with the other 

 species. Fl. Feb. 



This should perhaps form a distinct genus, differing from Podostcino7t 

 in its solitary stamen. If so, it may take the name Mavalia from the 

 name, Mahawdli, of the river where it and all our species of the family 

 are found. The Brazilian genera Oserya and Devillea are also mon- 

 androus, but quite unlike this in vegetative organs. 



CVIL— NEPENTHACE^. 



Semi-shrubby, climbing by prehensile petioles, 1. alt., without 

 stip., petiole dilated at end into large pitchers with the blade 

 forming a hinged lid; fl. numerous, small, regular, dioecious, 

 in large panicles ; perianth with 4 deep segm. ; stam. about 8, 

 monadelphous, forming a central column, anth. extrorse ; ov. 

 superior, 4-celled, with numerous ovules on the septa, stigma 

 sessile, large, lobed ; fruit a capsule, splitting loculicidally into
