and have usually a nervature that is more perpendicular to the 

 rhachis. On these grounds, it may be allowable to separate the 

 var. elongatum, but, in my judgment, certainly not on the mere 

 ground of the form of the fronds.

S. SORBIFOLIA (L.) J. ISm., var. j-eptocarpa (Fee) Benth., 

 [Acrostichurri). 

 Common in the scrubs of the Cairns district, climbing the trees 

 to a great height. The delicate fruiting fronds I did not see 

 growing, save at the top of the plant, generally high up. Mr. 

 Bailey rightly says that this is "one of the most beautiful of climb- 

 ing ferns." 



S. PALUSTRis (Burm.) Bedd.; Acrostichum scandeiis Hook. 



Climbing up bushes and trees on the margin of Lake Barrine; 

 also in swamp close to Cairns; Aug., 1913. 



The pinnae of this strong climber are very sharply serrate 

 throughout. Mr. Bailey seems to have had before him specimens 

 that were "entire or slightly dentate,'' but mine are all sharply 

 serrate, in this agreeing with Beddome's figure in "Ferns of 

 Southern India" (t. 201).

Domin (Prodr., p. 120 ff.) has some very valuable notes upon 

 the species of this genus, Doodia, and especially upon D. caudata, 

 which always has, at least, its lower pinnae free and separate ("frei 

 und getrennt"). My specimens appear to be quite typical of the 

 normal form (var. normalis Dom.).

In bush at edge of track to Coffee Plantation, on northern side 

 of the Barron River, Kuranda; Phillip Mackenzie, July, 1913. 

 This is a striking species, with a large Indo-Malayan range.
