spiral of flowers round the spike. But as Mr. Sargent remarks, 

 many insects also visit these. Indeed they are of a type visite<l 

 by all sorts of insects. 



The next type is Loranthus linophyllus, a tubular flower. It is 

 visited by Zosterops Gouldi. Next comes Acacia, already referred 

 to, and then Eucalyptus. Mr. Sargent estimates that E. macrn- 

 carpa has 1,400 stamens, and these form a band, one inch wide, 

 and oj inches in circumference. The stigma is less than 1 mm. in 

 diameter, so that the pollen-bearing surface w&s 3,000 times the 

 area of the pollen -receiving surface. In the case of this species, 

 he has not seen birds pollinating it, but has observed E. redunca 

 and £J. caJophylla being visited by Zoslerops Gouldi, and species 

 of Glyciphila. From my knowledge of Eucalypt flower-structure. 

 I should be more inclined to look upon tlie hrush-tongued lories as, 

 to use JMr. Sargent's phrase, the "offlcial" i:>ollinators. 



In Beauforlia sparsa, he sees another type, more specialised for 

 birds; and he lias observed that the anthers rub against cheeks, 

 foreheads, and throats. This type reaches furtlier specialisation in 

 Calothaynniis sang'tvineus. In this, the anthers are arranged in 

 bundles, so placed that they press against the heads of the birds 

 (Glyciphila and Zosterops) visiting it. Other flowers mentioned 

 as ornithophilous are AstroJoma diiiaricnta and Bhincoa cdiiescens. 

 Anigozanthos humilis and A. Manglesii, he has not personally 

 seen visited by birds, but his brothers have seen thi?m at the 

 former, and some friends have seen small birds at the latter. I 

 may say that I have repeatedly seen Acanthorhynchus feeding 

 on A. Manglesii in the King's Park in Peith, and I noted their 

 black heads covered with yellow pollen. 



Mr. Sargent names three of the Papilionacese as ornithophilous 

 — Tenipletouin retusa, Crotalaria Ctiwidnghtimii, and Clianthns 

 Dampieri. 



His last type embraces the Proteaceae, and he mentions Ade- 

 nanthos cuneata, Baiiksi't attenuatn^ B. MeAiziesii, Dryandra 

 fioribunda, and D. carduacea.
