 Actinostrobus pyramidalis. Miq. (Ann. Bot. XXVII. 106. p. 321—345. 

 4 pl. 3 textfig. 1913.) 



Actinostrobus pyramidalis Miq. is a smal! tree (seldom above 

 10 ft high) confined to Western Australia. The principal results 

 of the author's investigations are as follows: 



About three nionths elapse between pollination and fertilization. 

 Each microsporophyl! usuall}^ bears three sporangia. The mature 

 pollen-grains are uninucleate. From 6 to 12 ovules are borne in each 

 female cone. A Single megaspore mother-cell is formed in the nu- 

 cellus, and no spongj^ tissue is organized. Archegonia are formed 

 from the alveoli, after the cutting off of some small cells at base and 

 apex, and are deep-seated, a group of 25 to 30 being found abutting 

 on the lower end of each pollen-tube, which reaches about half-way 

 down the prothallus. Large secretory cavities are found in the tissue 

 of the integument. alternating with the wings. The older cells of 

 the prothallus are generali}^ 2- to 4-nucleate. The male gametophyte
