Series Curviptera. 



Fertile seeds greyish to dark brown. l|-3 mm. long, including the wing, somewhat 

 tapdole-like, or obliquely ovate to compressed quadrangular, with a small incurved 

 wing at the base, and with 1-4 more or less prominent longitudinal ridges. Hilum 

 terminal. 



Sterile seeds light to dark brown, polymorphic, the narrow ones subulate to 

 clavate, the longest about 4 mm . 



E. Burracoppinensis n. sp. E. Oldfieldii. 



E. Burracoppinensis n. sp. (inedit.). 



Fertile seeds dull, greyish-brown. l|— 3 mm. long, including the wing, which is 

 about 1 mm. long. 1|— 2 mm. broad, tadpole-like, ovate or obliquely ovate, truncate, 

 with three or four prominent ridges, and one to three faint lines or ridges, the rather 

 narrow, firmly winged margin terminating in a small, broadish, incurved, tail-like 

 wing, and more or less covered with a very thin, transparent, deciduous, hyaline 

 membrane ; ridges usually following the curvature of the seed, the more prominent 

 ones with a very narrow rudimentary wing, differing in colour to the thin, minutely 

 pitted testa ; endosperm dark coloured (white in all the other species). Hilum terminal, 

 rather small, the scar surrounding it usually obliquely truncate, with or without a 

 shallow depression. 



Sterile seeds glossy, polymorphic, the broad ones very angular and curved 

 somewhat similar to the fertile, light brown, 2-3 mm. long, mostly compressed. The 

 narrow ones dark brown, 2-4 mm. long, quadrangular clavate to subulate, about as 

 numerous as the broader ones. 



The terminal hilum is unusual in a winged seed. Its position is near the winged 

 Coryrnbosse. 



The long or longish wing of the fertile seeds, and the long narrow, sterile seeds 

 and hyaline membrane readily distinguish this species from all the others. 



E. Oldfieldii (not figured). 



" Fertile seeds imperfectly and quite narrowly membranous at the margin, larger than the partly 

 narrow sterile seeds. Ripe fertile seeds black, scarcely above 1 line long; sterile seeds unequal in size." 

 (" Eucalyptographia.") 



Fertile seeds glossy, dark brown, 2-3J mm. long, 1-2 mm. broad, polymorphic, 

 compressed quadrangular, somewhat pyramidal to navicular, all more or less wrinkled 

 on the face and back, the thin testa pitted rugose, sometimes expanded into a thin 

 membrane along the edge and at both ends, so as to form a rudimentary wing Hilum 

 terminal, small. 



Sterile seeds glossy, dark brown to dark reddish -brown, polymorphic, the narrow 

 ones clavate up to 4 mm. long.
