This interesting plant offers points of contact with ee genera Avrainvillea, Udotea, 
and bgiks (Bull. Torrey Club 32: 569), but is perhaps most at home in Udorea, 
where Mu urray (7. c.) has doubtfully placed it. But we find n oe for supposing 
with Murray that this ‘form’? is an “ imperfect state.” In color and general habit 
it has most in common with Avrainvillea, but it is corticated ; a general character of 
the cortex, ho owever, is rather different from that of any other de scribed species of

Udotea See abi and without the ultimate lateral nodular excrescen ircegularly 
cristate-pectinate coherent branchlets of that species. In the nature os the cortex it 
closely resembles Cladocephalus scoparius; in fact, the species stands in much the sam 
relation to Cladocephalus that Udotea sae hath ata does to Penicillus, Udotea coe 
tinata being a Penicillus except in having a flabellum instead of a capitulum.
