Phyllaries: (i) linear, long, and spreading; (2) long, narrow, and 

 spreading, of the orgyalis type; (3) lanceolate, loose, and spreading. 



Rays: (i, 2, 3,) without pistils; (i) 11-14, rather more decidedly 

 orange than in Maximiliani, and more or less bifid at end; (2) 14-21, 

 clear bright orange-yellow, essentially Maximiliani color, many with 

 tips deeply bifid; (3) 30, light yellow, more or less emarginate at end, 

 and largely in 2 rows. 



Diameter oj disk: (i) about 10 mm.; (2) about 16 mm.; (3) about 

 17 mm. 



Disk bracts: (i) very hairy at end, covering disk buds at early stage; 

 no produced naked tips; (2) very hairy at end, covering disk buds at 

 early stage, and with short naked tips; (3) hairy at end, covering disk 

 buds at early stage, their tips elongate and sharp, pale green, not hairy. 



Stigmatic branches: (i, 2, 3) orange. 



Achcnes: (i, 2, 3) entirely glabrous. 



Pappus scales: (i) 2, about or hardly half length of corollas; (2) 

 2, about as long as in orgyalis, sometimes with well defined intermediate 

 squamellae; (3) over half length of corollas. 



The hybrid is on the whole intermediate. It is surprising that the 

 dark disk is not dominant. A remarkable feature is the deeply bifid 

 ends of the rays in the hybrid, greatly exaggerating the character of the 

 parents. The appearance of intermediate pappus squamellae is a 

 common feature in true orgyalis. Essentially this hybrid is evidently 

 known to the trade, although not described. We have a purchased plant 

 belonging to it, but differing from the one just described in the following 

 particulars: stems freely branching as in orgyalis, and plant as tall as 

 orgyalis .-"^ disk olive green in bud ; peduncles rather slender; rays 18-24, 

 only slightly emarginate at end; disk about 15 mm. in diameter; lobes 

 of disk corollas light orange, the extreme tips reddened, or whole lobe 

 suffused with red. F. C. Heinemann, of Erfurt, Germany, advertised 

 a supposed hybrid of this group, calling it H. perennis hybridus pyramid- 

 alis; but from his figure it seems to be simply H. Maximiliani. 



It is clear that our hybrid does not agree with H. Dalyi Britton or 

 H. Kellermani Britton. Dr. J. C. Arthur writes me that some years 

 ago, near Madison, Wisconsin, he saw a considerable growth of H. 

 Kellermam, and near by H. grosseserratus and H. orgyalis, or what 

 appeared to be such. He had the idea that H. Kellermani was a hybrid 

 between the latter plants, but on attempting to make the same cross 



'C. PuRDY (1916) advertises a very tall form of H. Maximiliani, said to grow to 

 II ft. in height. Is this perhaps a hybrid ?
