 TJrbewoliner Australiens, einer Marsilea-ivvLoSxt, nebst Bemer-

 1862. 



Dr. Hanstein describes the structure of the fruit of a species 

 of Marsilea, called Nardoo by the aborigines of Australia. It is 

 eaten by the natives, and was used as food for some time by King, 

 the survivor of the late unfortunate Australian exploring expedi- 

 tion. The species appears to be new — so far, at least, as can be 

 judged from fruit alone. Some remarks upon other species of the 

 genus are also given. The paper is illustrated by a plate con- 

 taining a number of well-executed figures.

Z. V. B. Vol. xi. p. 345. 



Dr. Milde describes at length five species of Equiseta, some 

 of which have been previously shortly noticed by other authors. 

 At the end of the paper are some remarks upon the importance 

 of the position of the stomata in classifying Equiseta, and on the 

 assistance in distinguishing species which is afforded by the differ- 

 ences exhibited under the compound microscope by the siliceous 

 coverings of the furrows of the branches. Dr. Milde divides 

 Equiseta into " phaneropora " and " cryptopora," the former 

 having the stomata in the same plane with the epidermis, and the 

 latter having the stomata underneath the epidermis, which is 

 ruptured transversel3^ The cryptopora are again divided into 

 " monosticha" where the stomata are in a single row, and pleios-
