Summary Using the method of protoplast fusing, attempts were made to isolate hybrids between a normal green, nicotinic acid deficient female (nic 2 ) and a pale green, glucose deficient male (pal 2 ) of the liverwort Sphaerocarpos donnellii Aust . Th

Sphaerocarpos donnellii Aust. develops a substrate-specific morphology when grown under sterile conditions on the same medium for a period of 10 months. Media containing monosaccharides gave an increase in total chlorophyll content, and increase in g

Allen (I9I7) found eight chromosomes in both male and female plants of Sphaerocarpos Donnellii. One of the chromosomes (X) in the female is much larger than any of the other seven and corresponds to a very small chromosome (Y) in th e male. During th

The studies here reported were made on two aberrant forms of Sphcaerocarpos Donnellii Aust. which were first observed by Dr. C. E. Allen in his cultures which have been growing under greenhouse conditions since early in I9I6. Clones may be kept growi

From crosses of the mutant strains 402, 404 or 444xwild-type of Sphaerocarpos donnellii about 104000 tetrads with 4 sporelings, and about 20 000 tetrads with 3 sporelings were analyzed. No tetrad was found in which non-reciprocal segregation was indu

Summary Spores of the liverwort Sphaerocarpos donnellii Aust. were x-irradiated. Among 9557 plants five nutritionally deficient mutants could be identified. Three of them grew when supplemented with nicotinic acid. Crossing experiments demonstrated t

— In polarotropism of the chloronema of the fern Dryopteris filix-mas (L.) Schott and of the germ tube of the liverwort Sphaerocarpos donnellii Aust. a phytochrome action in blue and u.v. was presumed[1, 2]. In the present paper this assumption was
