ness and coloration between the parents. — Comptonia asplenifolia, from Nova Scotia to Ten- 

 nessee, is strictly deciduous. Myrica Gale, a deciduous species, is distributed through north- 

 ern regions, while Myrica inodora is evergreen. Seedlings are here described for the first 

 time and their comparative morphology and that of the adult plants are traced. The author 

 finds that the characteristic root-tubercles are due to Actinomyces myricarum, first described 

 as the causal organism by himself. Exact phenological records have been kept, as to the 

 maturation of the floral parts and the period of blossoming in April and May. Other details 

 with a list of synonyms and a bibliography are given. — John W . Harshberger.

 Bot. Mag. Tokyo 33: 73-93. 1 pi., 2 fig. 1919. — Porphyra leucosticta var. siiborbiculata and 

 P. linearis are rock-inhabiting species abundant on the shores of Oshoro Cove near the Marine 

 Laboratory of the Hokkaido Imperial University. To study them the author had built a 

 sloping concrete block on a reef where the algae grew abundantly. The block was 4 feet high, 

 terraced 3 inches wide every foot, and inclined about 45°. The first spores were found in late 

 October attached to the block and to the 60 stones set into the terraces. Repeated towings 

 with fine nets failed to reveal any spores in the water. The development of these spores 

 into mature fronds was followed and the current account of carposporc formation confirmed. 

 In April following, fronds with mature carpospores were transferred to the laboratory and 

 cultivated in beakers. The water was kept at a temperature of 6-14°C. and the cultures 

 were carried on in a well-lighted room but not in direct light. The carpospores germinated 

 in the second week. In about 5 weeks mature branched filaments were produced. Certain
