ANEMIA. 



AN'BURY, or Ainbury, popularly club- 

 root or fingers-and-toes, is a disease peculiar 

 to the Brassicaceae. It consists in the for- 

 mation of galls or warts, often of large size, 

 on the lower part of the steins and the 

 roots. It has been attributed to various 

 causes : in some instances, the larvae of a 

 weevil have been found within the galls, to 

 which their origin might fairly be attribu- 

 ted. The Aphidae have also been supposed 

 to produce these tumours ; this Buckton de- 

 nies. The later researches of Woronin have 

 traced this disease to the agency of an ally 

 of the Myxomycetes, called Plasmodiophora 

 BrassictB.

ANCHOEEL'LA, Ouvier. A genus of 

 Crustacea, of the order Siphonostoma. 



Char. Body short, produced in front into 

 a kind of neck, which is transversely rugose ; 

 arms two, furnished with a sucker or adhe- 

 sive disk at the end, and confluent through- 

 out their length. 



Two British species 



A. uncinata (PI. 19. fig. 7), milk-white ; 

 found on the gills and gill-covers of the cod, 

 haddock, and whiting ; length about 1-2". 



A. rugosa, found on a species of cod; 

 length about 1-3". 



The above characters refer to the female.

Char. That of an Enterodelous Bodo, with 

 a nioveable setaceous foot.

A. duodenalis=Dochmit(s duod. 



A. dysenterica (PI. 53. fig. 4) is of doubt- 

 ful position. It is about 1-100" in length ; 

 curved and transparent in front, yellow and 

 opake behind, and expanded at the base. It 

 is firmly attached to the mucous membrane 

 in large numbers ; and occurs in the dejec- 

 tions of diarrhoea and dysentery in hot cli- 

 mates.

Char. Ovate or elongate, free or adherent ; 

 flagellum single, trailing at the end, vibra- 

 tile elsewhere ; a nucleus and vesicle present. 



A. sigmoides, among decaying Fiicus, 

 Jersey ; length 1-5000".

the peculiar mode of splitting of the fruit, 

 somewhat analogous to that which is found 

 in Jungermannia, the urn-shaped capsule 

 dividing perpendicularly when ripe into 

 four or eight valves, which usually remain 

 attached together at their points '(figs. 10 

 and 1 1) . But the capsules always differ from 

 those of Jungermannia in the presence of a 

 columella. The cells of the leaves are pa- 

 renchymatous, with their walls thickened, 

 and somewhat papillose on the surface. The 

 calyptra at first covers the capsule entirely, 

 then splits off as a mitre-shaped or bell- 

 shaped cup. The archegonia and antheridia 

 are either on the same or distinct plants, 

 and the latter terminal on distinct branches. 

 The few British species are natives of rocky, 

 usually alpine 



districts, and 

 belong to the 

 genus Andrcea. 

 In Acrochis- 

 ma, an antarc- 

 tic genus, the 

 sporange splits 

 only part of 

 the way down.
