PLATE 286. 



Types of Cotyledons, natural size. Figures 1-4 beloiio- to Reniformee. Section 

 I. Large Cotyledons. Series (la) Corymbosge-Peltatse. They have the largest 

 cotyledons of all the species, and the advanced seedlings are characterised by minute 

 stellate hairs or seta. 



la, lb, E. calophylla. Hypocotyl moderately short ; cotyledons large, sometimes slightly undulate, 

 with 3-5 faint radiating nerves, and more or less setose; la, 30 x 22mm. (Perth, Western Australia, 

 Woods and Forests Department). (See also Coloured Plate No. 2). 



2, E. jkifolia. Hypocotyl short ; cotyledons nearly orbicular with a prominent midrib and faint 

 lateral nerves, setose above the hypocotyl, 30 x 25mm. This and the preceding are the largest cotyledons 

 of all the species. (Botanic Gardens, Sydney). (See also Coloured Plate No. 2). 



3, E. Ticematoxylon. Hypocotyl short, as in the preceding, but slightly smaller with 3-5 faint radiating 

 nerves; setose above the hypocotyl. (See also Coloured Plate No. 3). 



4, E. eximia (Berowra, A. Murphy). Cotyledons smaller than the preceding, but sometimes as large ; 

 venation often indistinct; densely setose above the hypocotyl. (See also Coloured Plate No. 3). 



Figs. 5-12, except 7 and 8, belong to Section 2, Medium Cotyledons, Series (2a), 

 Corymbosse-Peltatse. The cotyledons depicted vary from 9x5 mm. to 11 x 8 mm., 

 and are moderately uniform in shape. (See Coloured Plate No. 4). 



5, E. maeulata, Wyong N.S.W. (Andrew Murphy, 1913). Reniformae, Medium Cotyledons, Series 

 2a, Corymbosae-Peltatae. (See Coloured Plate No. 4). 



6, E. pyropkora, Bourke district, N.S.W* (Andrew Murphy). Series 2a. 



7, E. Watsoniana, Botanic Gardens, Sydney (J. L. Boorman). Series 2b. Corymbosae-Non-Peltatse. 



8, E. latifolia, C'ullen Paver Northern Territory (Dr. H. I. Jensen, July, 1916). Series 2b. 



9, E: coryrnbosa, Lawrence, N.S.W. (J. V. de Cogue). Series 2a. (See Coloured Plate No. 4). 



10, E. trachyphloia, Gungal, N.S.W. (J. L. Boorman). This species appears to have the smallest 

 cotyledons of any of the Corymbose ; its fruit are also small. Series 2a. (See Coloured Plate No. 4, No. 5) 



11, E. peltata, Brisbane, Queensland (F. M. Bailey, May, 1906). Series 2a. (See Coloured Plate 

 No. 4). 



12, E. Bloxsomei, Hippong, Queensland (H. S. Bloxsome). Note the first pair of leaves above the 

 orbicular cotyledons are alternate. Series 2a. 



Figs. 7, 8, 14, 15, 19, 25, illustrate members of Section 2, Medium Cotyledons 

 Series 2b, Non-Peltatse. The cotyledons do not show a great deal of variation. They 

 range from 13 x 10 mm. to 20 x 13 mm., and like other, species of the Corymbosse, the 

 more advanced seedlings are furnished with stellate hairs or seta. 



13, E. tetrodonla, Darwin, Northern Territory (G.F. Hill). This is a member of the Reniforms. 

 Series 2c. Eudesmeae. The Cotyledons are more oblong than those of the Corymbosae, but they resemble 

 the latter in the setose vestiture of the more advanced seedlings, and are readily distinguished from Series 2a 

 in being non-peltate. (See Coloured Plate No. 5). 



14, E. dichromophloia, Eidsvold, Queensland (Dr. T. L. Bancroft). Series 2b.
