but we have been able to study in the Kew Herbarium two s speci- 
ens of K. tasmanica named by Harvey himself, and collected in

specimen rébonabbae in form, consistency, and structure the plants 
sent to us by Mr. Lucas. Gunn’s plant, on the other hand, is

of Archer’s or Mr. Lucas’s specimens, Gunn’s deren bears pro-

Mr. who, as mentioned above, ae he has Tank plants pro-

new specimens hoe in the fact that ‘a Lucas has succeeded in

At first sight these specimens would not readily be referred to 
R. robusta, owing to their slenderness; but they have the typical 
structure of Rhabdonia in their thallus, and one of these (the mid- 
Summer specimen) bears typical cystocarps. As to their slender 
habit, this does not prohibit the inclusion of Mr. Lucas’s plants in 
the species, for in ane herbarium of the British Museum there are 
specimens of intermediate size which form connecting-links with 
the normal robust state of the species. Among these is the plant
