a pronounced and conspicuous feature.* In B. rhizophora they | 
are often nearly as large апа аз long аз Ше branch itself, so that 
the branch appears laterally attached near its middle. In the 
Californian B. corticulans Setchell (Phyc. Bor.-Am. 626), a plant 
very different in size and habit, the corresponding rhizoids are 
much smaller than the branch and are commonly short and numer- 
ous. In a plant from farther north on the Pacific Coast, dis- 
tributed in the Phycotheca Boreali-Americana (по. 1028) ав” 
Bryopsis hypnoides, also different from В. rhizophora in size, habit, 
and mode of branching, the corresponding rhizoids are fewer and 
longer than in B. corticulans, but are also much smaller than the 
branches from which they spring and look like rhizoids rather 
than like downward continuations of the branches themselves. 
In the “Bryopsis Rosae," from the Falkland Islands, figured by 
Kützing (Tab. Phyc. 6: pl. 84. f. II), some of the ramuli have 
decurrent rhizoidal bases, but these ramuli have twice the diameter 
of those of the Peruvian plant; and whatever the relationship of 
the Peruvian plant to that figured by Kützing, it is rather manifest 
that the Bryopsis Rosae of Kützing is not the same as the original 
Bryopsis Rosae of Agardh and of Gaudichaud. | 
In the form and arrangement of the ultimate ramuli, Bryopsis 
rhizophora is rather suggestive of Kiitzing’s figure of B. adriatica 
(Tab. Рћус. 6: pl. 79. f. 116" ), but the form of the whole plant is 
very different, and Kiitzing’s figure shows conspicuous scars from 
deciduous gametangia which we have not noted in the Peruvian 
specimens. This figure of Kützing's is currently cited as belonging 
to Bryopsis cupressina Lamour.,f to the original figure of which 
the Peruvian plant bears little resemblance. 
In addition to its own gametangia, this Peruvian Bryopsis | 
exhibits what appear to be the sporangia of an endophyte, prob- 
ably a Chytridiaceous fungus. Тһе form of these sporangia is
