Hawaii. Of the last, all but four occur also in Fiji. There is thus a very 

 small element peculiar to Hawaii and Tahiti alone. Some of them will 

 no doubt be found in the Fijian area ; whilst two of them, Acrostichum 

 squamosum and Lycopodium venustulum, are high-mountain forms in 

 Hawaii and Tahiti, which have evidently failed to find a suitable elevation 

 in Fiji.

 ARE NOT found EITHER IN Fiji OR TAHITI (mainly from Hillebrand)

Endemic Genera of Ferns in Hawaii 



Hillebrand gives two genera of ferns peculiar to Hawaii, one, Sadleria 

 of Kaulfuss, "scarcely distinct from Blechnum," and containing four 

 species ; the other, Schizostege, constituted by himself, and represented 

 by a single species found in only one or two of the islands.

On THE Dispersal of Composit^e by Birds 



The goldfinch's habit of pecking at the heads of thistles, and pulling 

 out the achenes in bundles, is well known. Gatke mentions two suggestive 

 instances of birds feeding on the fruits of a Composite plant. According 

 to this observer, the Scarlet Grosbeak (Pyrrhula erythrina), when it alights 

 on Heligoland, always feeds on the achenes of Sonchus oleraceus, which it 

 picks off the plant; whilst the Parrot Crossbill (Loxia sp.), feeds in 

 Heligoland on burrs and thistles {Heligoland as an Ornithological Obser- 

 vatory, pp. 407, 409). See Note 91.
