others with a filiform rhachis may occur on the same individual, whilst 

 Kamienski's other two varieties evidently represent only states of less vigorous 

 growth. 



10 TJ. foliosa (Linn. Sp. PL ed. ii. 26) ; an aquatic floating herb ; 

 stolons up to several yards long, l-l^ lin. thick, giving off at 

 intervals of 2 or more in. solitary or more often fascicled branches ; 

 branches spreading up to over 1 ft. long, densely or loosely; leafy 

 except towards the base ; leaves all of one kind or only diftering in 

 the presence or absence of bladders, alternate, up to 3 in long, 

 compound-pinnate, lowest pinna at or near the base, ultimate 

 segments capillary, sparsely and minutely setose, primary (rarely 

 also the secondary) midribs occasionally dilated and spongy ; bladders 

 very numerous on some leaves (in extreme cases most of the seg- 

 ments replaced by bladders), sparse or on others, subobliquely 

 globose, 1-^ lin. in diam., mouth truncate with a few long branched 

 delicate cilia ; raceme up to 12-flowered; peduncle rising from the 

 branch-fascicles, \ to over 1 ft. long, slender or sometimes milatecl; 

 bracts elliptic or ovate, obtuse or subacute, l^-H ^i"- ^^^S^ ^^^' 

 branous, adpressed to the pedicels, lowest 1-3 barren ; bracteoles U; 

 pedicels filiform, 2|-5 lin. long (in the African specimens), oblique y 

 erect during flowering, then gradually recurving and slightly 

 lengthening, not thickened upwards; sepals broad-ovate, connate 

 at the base, obtuse or subacute, 1^-2 lin. long, membranous, scarcely 

 enlarging after flowering ; corolla yellow, 5-8 lin. long ; upper Up 

 Totundate-ovate, 2-3 lin. long ; lower lip broad, suborbicular, sub- 

 emarginate, 4-5 lin. long, adpressed to, and as long as, the upper,

 long; anthers i lin. long, cells quite confluent; ovary globose, 

 style short but distinct ; upper lip of stigma 0, lower hp large, broaa

 very flat, -»-l| lin. in diam., with a narrow membranous wing au 

 round ; embryo slightly concave on the top with several obscure 

 leaf rudiments, discoid. DC. Prodr. viii. 6 ; Benj. in Mart. J^ t-

Also in Tropical Africn, Madagascar, and throughout Tropical America. 

 The number of seeds in each capsule and their size vary. The ^^^'^^^^^ 

 form was described by S. Hilaire {Voy. Distr. Diam. ii. 427) as U. o^o^P^ ^ ^ '^ 

 from Brazilian specimens. It seems to be the form prevalent in Africa, un ^ ' ^jg| 

 says that the American specimens have sometimes as many as 24 ®^^ r" ^gntly 

 I have never seen so many in the mature state. V. foliosa produces '. 'j .^j^^ 

 slender filiform shoots from the back of the stolons without definite mspos^^^^ 

 and bearing only scale-like minute leaves (aerial shoots of Goebel). A j
