140 FLORA OF STRADBROKE ISLAND, 



habitat is not given in Bentham's and Mueller's Flora. First of 

 these, Boronia pinnala, Sm., is met with in abundance along the 

 edge of swamps forming often a dense thicket of from five to six 

 feet in height. This when in bloom is a very attractive plant. 

 B. parviflora, Sm., a much smaller species is frequently found in 

 various localities. On some spots of very dry ground high up 

 on the hill sides usually under the Casuarina and French we 

 noticed large quantities of Macarthuria neocambrica, F.v.M., a small, 

 probably an annual, plant belonging to Ficoidecc. The following 

 might bo added to the diagnosis of this species given in the 

 "Flora Australiensis " : — Habit of plant compact, 6 to 12 in. 

 broad, 3 to G in. high, composed of a few lanceolate radical leaves 

 3 or 4 in. long, which taper into rather long petioles. The rest 

 of the plant formed of flowering branches which are dichotomously 

 divided, bearing few small linear-oblong, nearly filiform leaves. 

 Flowers near the ends of the branches, small, and pedicellate. 

 Petals white, seeds black, and muricate. Flowering in October. 



Scattered over both Stradbroke and Peel Island are two species 

 of Bipodium, the common D. punctatum, E. Br., and another new 

 species of which the following is a diagnosis :
