EXPLANATION OF PLATES 248-251. 



PLATE 248. 



Bracts and Bracteoles. 

 1a. (a) Bracts (there are up to three, fused at the edges, to each bud), enveloping the single bud. 



Where the pedicels are attached to the peduncle, the scar of the more inclusive bracts 

 which envelop the umbel will also be seen. 



1b. Bract at base of pedicel enveloping the entire umbel, of which only one bud is shown. 



lc. Plan of a bud and bracts (1a (a) ), the bracts surrounding the bud (b). All are from E. pyriformis 



Turcz. var. ehngata, cultivated in Botanic Gardens, Sydney (W. F. Blakely, December, 1917). 

 2a. Twig of E. Camfieldi Maiden, showing leaves and undeveloped umbels. 



2b. Umbel, enlarged, showing (a) bracts, enveloping the buds. From the type locality of E. Camfieldi, 

 viz., about 100 yards south of the 17 mile-post, Galston-road, Hornsby, Sydney (W. F. Blakely 

 and D. W. C. Shiress).' 



3a. Immature buds, somewhat irregular in contour, of E. de Beuzevillei Maiden. 



3b. Young umbel, showing enveloping bracts, still fused by their edges. Same species, and all specimens 

 from the type locality (W. A. W. de Beuzeville). 



4. Enveloping bracts, as yet joined together, E. miniata A. Cunn., Goody Goody, Western Australia 

 (W. V. Fitzgerald). 



5a. An umbel, natural size, showing a bract at (a). 



5b. The same umbel, greatly enlarged, (a) a bract; (b) a bracteole. The enclosed buds are shown 

 shaded. Although in the enlarged drawing the bracts have the appearance of being continuous 

 with the flattened peduncle, this is really not so, for at an early stage the bracts wither, and, being 

 articulated to the peduncle, drop off. E. pyrophora Benth., Saxby River, Northern Queensland 

 (Miss Florence Sulman). See Part LVIII, p. 465. 



6a. Buds with enveloping bracts (a). 



6b. The enveloping bracts, with the buds removed. 



6c. Enveloping bract, much enlarged. E. letrodonta F.v.M. All Darwin, Northern Territory (Prof. W. 

 Baldwin Spencer, 1911). 



These bracts are in pairs, more or less persistent, confluent with the peduncle, broad 

 lanceolate to navicular, concave, thick, slightly keeled, the margins uniting, subperfoliate, 5-8 mm 

 long, 3-5 mm. broad. They are not unlike the bracts of some of the Loranthaceae. Enlargement 

 concave and hooded, superposed by a strong solid apicular process which is also slightly concave. 

 The lower or larger cavity appears to be the impression caused by the outer bud; the smaller 

 upper cavity represents the impression of the top of the central bud, which is usually longer 

 than the lateral or outer buds. It would appear that in the early stage the bracts enveloped 

 the three buds, are free at the apex, and the apicular portion is a protection for the lower part of 

 the bract. 



7a. Umbel, natural size, of E. fici folia F.v.M., showing subtending bract. 



7b. Umbel, natural size, showing bracts (a) and bracteoles (b). 



7c. Showing the bracts (a) and bracteoles (fo) in plan. 



7d. Umbel, natural size, showing bracts (a) and bracteoles (6). 



7a, 7b, and 7d show progressive stages of development of the buds. Note that the opercula 

 in 7b and 7d show more or less clearly where a second operculum has fallen off fronTeach bud 

 All the above from E. ficifolia, cultivated in the Botanic Gardens, Sydney. 



7e. Showing two bracts, E. calophylla, cultivated in the Botanic Gardens, Sydney.
