ON THE LAMINAKIACEAE OF HOKKAIDO

2. Kjellmaniella gen. nov. 
Plants of this genus have a blade furnished all over the 
marginal portions with closely set gyrate puckerings, of which the 
depressed portions are so identical with the protuberant ones in 
shape, that the pattern of the puckerings on the upper and on the 
lower surfaces show no marked difference between each other. 
The median fascia is plane and clearly defined from the marginal 
portions being elevated to one surface. The mucilage ducts are 
present in both stipe and blade. The holdfast consists of filamen- 
tous hapteres. 
There are two species from the region under study which 
should be placed in the present genus ; one is K. gyrata from 
Kushiro and Nemuro and the other is K. crassifolia from Oshima. 
While the latter is new to science, the former is the plant which 
Kjelt.man (1892) studied with the specimens collected in Hokkaido 
and preserved in the herbarium of the Academy of St. Petersburg. 
He recognized it as a new species of the genus Laminaria and named 
it Laminaria gyrata. Since the specimens he examined were dried 
incomplete ones, he could not observe depressed and protuberant 
gyrate puckerings on the blade surface but merely sporangial sori 
forming irregular gyrate markings, after which the species was 
named Laminaria gyrata. The sporangial sori in this species are 
always formed only in the depressed portions and thus naturally 
produce the beautiful gyrate pattern. These characteristics are 
considered to be enough to warrant the establishment of a new 
genus separate from the genus Laminaria. Here the author pro- 
poses to name it Kjellmaniella in honor of Kjeleman whose contri- 
butions to the knowledge of our Laminariaceous plants deserve 
our high appreciation.
