Explanation of Plates (168-171). 



PLATE 168. 



E. latifolia F.v.M. 

 1. Juvenile orbicular leaf. Not quite in the alternate stage, but the youngest leaf I have seen. 



Bathurst Island, Northern Territory. (G. F. Hill, No. 464.) 

 2a. Mature leaf ; 26, large corymbose panicle, showing buds, flowers, and very young fruits ; 2c, front and 



back views of anther ; 2d, fruits of varying size and shape. Bathurst Island. (G-. F. Hill, No. 469.) 



3. Immature fruit, markedly urceolate. Pine Creek, Northern Territory. (Dr. H. I. Jensen, No. 357.) 



4. Mature and starved fruits. Between Bull Oak and Crescent Lagoon, Darwin to Katharine River. 



(Prof. W. Baldwin Spencer.) 



5. Mature fruits with remarkably slender peduncles and pedicels ; the leaves comparatively small. 



Darwin to Roper River. (Prof. W. Baldwin Spencer.) 

 6a. Mature leaf; 66, immature fruits. McKinlay Flats, Northern Territory. (Dr. H. I. Jensen.) 



PLATE 169. 



E. Foelscheana F.v.M. (See also Plate 170.) 



1. (At back), portion of a large juvenile leaf (the original is 15 by 11 inches, and even larger were seen). 



Katharine River, Northern Territory. (Prof. W. Baldwin Spencer.) 



2. Small, scarcely urceolate fruits, attached to a mature leaf 20 to 16 cm. Katharine River. (Prof. 



W. Baldwin Spencer.) 

 3a. Mature leaf ; 36, immature buds ; 3c, immature fruit. McKinlay River Flats. (Dr. H. I. Jensen.) 

 4a. Twig, bearing buds and flowers ; 46, front and back views of anthers ; 4c and M, fruits, views end-on 



and in elevation. Darwin (correspondent of Mueller). 

 5. Mature fruits of the large or typical form, near Darwin. (Prof. W. Baldwin Spencer.) 

 6a. Mature leaf; 66, unusually oblong leaf; 6c, small, mature fruit. Track to Katharine River. (Prof. 



W. Baldwin Spencer.) 



PLATE 170. 



E. Foelscheana F.v.M. (See Plate 169.) 

 (The lanceolar-leaved form.) 



1. Twig with long lanceolar leaf and flat-topped opercula (compare fig. 4a, Plate 169). " North Coast' J 

 (Northern Territory). Robert Brown, " Iter Australiense, 1802-5." 



2a. Twig with shorter lanceolar leaf and fruits ; 26, fruit, end view. Darwin (correspondent of Mueller, 

 by whom the specimen was sent to the Calcutta Herbarium). 



3a. Small lanceolar leaf, comparable in size and shape with that of 6a, Plate 169. (Note the straight 

 insect markings, parallel to the secondary veins. They have also been observed in Eucalyptus 

 brachyandra F.v.M., but apparently not previously recorded); 36, small fruits; 3c, winged 

 seeds. Between Cullen River and Woolgni, Northern Territory. (Dr. H. I. Jensen, No. 418.) 



The lanceolar-leaved form of this species is referred to at pp. 5 and 6. It would appear that a 

 variety name for this form would not be justified in the present state of our knowledge, for 

 comparing Plates 170 and 169, it will be observed that there is much variation in the shape of 

 the leaves of the species. Further, if the fruits be compared, e.g., the small fruits, fig. 36 (Plate 

 170) with the small fruits 2 (Plate 169), and the large fruits, fig. 2a and 26 (Plate 170) with the 

 large fruits of fig. 5 (Plate 169), it will be seen that small and large fruits occur in both the typical 

 and lanceolar-leaved forms.
