E. Falklands, teste Hooker. 
Disrris. Recorded from all parts of the world, but many records require 
verification. 
Most of Hooker’s material is referable to B. Розе, and І am doubtful if 
any specimen ean be identified with В. plumosa of Europe.

This species, which occurs so plentifully in the Falkland Islands and 
Magellan districts, was described by the elder Agardh in 1822, and, though 
closely allied to B. plumosa of Europe, it is usually regarded as a distinct 
species. The plant differs from ВБ. plumosa in its larger size and more 
robust habit, but it is possible, as the authors remark in * Flora Antarctica,’ 
that it may be only “a large state of that very sportive species" (vol. ii. 
р. 492). They record, however, both species. А good series of spirit or 
formalin materialis necessary if species of this genus are to be dealt with 
critically. Till the point can be definitely settled it is advisable to adhere 
to the old view. Part of the original gathering is to be found at Kew. It 
was collected by Gaudichaud about 1820, and was named after Rose de 
Freycinet, the heroic wife of the commander of the ‘Uranie’ expedition 
(see Oliver, '09, р. 210).

New to the Falklands, This plant has in the past been wrongly united with 
C. adherens, and is presented thus in De Toni’s ‘Sylloge.’ It resembles that 
species in habit, but differs in structure and also in geographical distribution. 
It is, on the whole, a rarer plant, and, with the exception of Hariot’s (’89) 
record which may possibly concern C. adherens, has not been previously 
recorded from this region. A specimen from Kerguelen also exists, being 
collected during the ‘Challenger’ expedition and found un-named in the 
Kew Herbarium. The utricles of C. difforme measure 1 mm. by 150-200 
(rarely 300) and are much longer and larger than those of C. adherens, 
as was pointed out by Kützing (Tab. Phyc. vi. fig. 99) and later by 
Askenasy & Bornet.
