 Feb. 1905. p. 50—54.) 



Most Floras recognise two forms, 1. with purplish ray flowers, 

 2. with no ray flowers (discoideus). Mac Leod (Bot. Cent. XXIX. 

 p. 215) States that the two forms grow together, others (P. Clark „Essex 

 Naturalist". V. 12. p. 237. 1902) hold that the salt marsh form is ray- 

 less, the Inland form is rayed. The author has observed numerous flowers 

 on the Humber estuary, where Aster occurs on typical salt marshes^ 

 and also in Inland brackish ditches of land which has been reclaimed 

 from the estuary. The foUowing is his summary: „1. Aster tripolinm 

 when growing Inland possesses well-developed ray ilorets. Such plants 

 are the survivors of a former salt marsh flora. 2. The dominant form on 

 the salt marsh has sparingly rayed and non rayed heads on the same 

 plant. 3. As well-rayed plants occur in all parts of the salt marsh, it is 

 not possible to assign a definite habitat to each form. 4. A rayed head 

 has more disc florets than a discoid head, and the number of disc florets 

 increases with the number of rays 5. The florets of a rayed head are 

 larger than the florets of a discoid head." Plants with more conspicuous 

 flowers have thinner leaves, larger intercellular spaces, more Chlorophyll, 

 and a normal mesophyll in place of one „toute palisadique" (Lesage).

A preliminary contribution to an inquiry into the origin and distri- 

 bution of the mixed types of plants on higher altitudes of S. E. A ust r a- 

 lia, and the relation of this flora to other Alpine floras and to the ter- 

 tiary floras of S. E. Australia. Between 1875 and 1888, the author col- 

 lected 1019 species of plants (most of which were named by the late 

 Baron F. v. Mueller) between 600 and 2200 metres altitude on the 

 Australian Alps from the head-waters of the Yarra River in 

 Victoria^, north-east to Mount Koscinsko in N. S. Wales. The 

 main and lateral watersheds rise to a series of summits of about 2000 

 metres, and include several mountain plateaux e. g. OmeoPlains 

 (1000 m.), Bogong High P 1 a i n s (2000 m.), and the snow-clad plateaux
