The Gardeners' Chronicle in 1867 (32: 292) speaks of this 

 plant introduced by von Siebold under the name Hemerocallis 

 Kzvanso florc-plcno and states that it " is merely a variety of H. 

 fulva, with the leaves more or less distinctly marked with white 

 stripes, and the tawny-red flowers filled out with a tuft of smaller 

 petaloid segments in the center." 



Thus it appears that the H. fulva Kzvanso first introduced was 

 variegated as well as double-flowered. The variegation is evi- 

 dently of the chimeral type and plants with this type frequently 

 produce all-green branches. Hence it may well be that some of 

 the double-flowered plants with all-green foliage now in cultiva- 

 tion arose from the Kwanso Daylily. 



The propagation of these two daylilies is solely by vegetative 

 means. It can not be otherwise, for the pistils of the flowers are 

 entirely impotent. The two types are merely clons. 



It is generally considered that the clon of the Daylily Flore- 

 Pleno introduced by Veitch & Son is less double than the Daylily 

 Kwanso. It is to be noted, however, that these conditions are 

 exactly reversed in the first illustrations of the two. The plate of 

 von Siebold's plant published in 1866 (Gartenflora, pi. 500) 

 shows a semi-double flower, while that of Veitch's plant (The 

 Floral Magazine 1 : pi. /j) shows a flower much more double. 

 The writer has obtained entirely green-leaved plants under both 

 names Kwanso and Flore-Pleno from various nurserymen and 

 from various botanical gardens. These have been grown side by 

 side for comparison and study. There seems to be no difference 

 in the color of the (lowers and the various aspects of the habit of 

 growth. Some plants, however, have all flowers very double, 

 while other plants have semi-double flowers, with also many in- 

 ter-grades; various grades of doubleness may be found on the 

 same plant. 



In 10-24 Mr. Henry II. White, of the Department of Agricul- 

 ture, American Presbyterian Mission, in Anhwei, China, sent to 

 The New York Botanical Garden living plants of daylilies which 

 he had collected from an old abandoned cemetery. These plants 

 have green leaves and bear flowers of various grades of double- 

 ness with many flowers only semi-double. 



When plants of the Furopa Daylily are grown beside plants 

 having double flowers the former are earlier to bloom, have foli-
