The spirajs shown at 5 represent blend plants from the breed- 

 ing of D. harhatus upon D. Chinensis var. laciniatus. The foliage 

 is midway between the two parents, while the flower clusters and 

 rich color of the petals are like the male parent. On the other 

 hand, the large blooms and fringed petals show the influence of 

 the mother. 



A hybrid blend plant is represented at 6 of D. harhatus upon 

 D. latifGlius. Both parents are hardy perennials, the male being 

 the Avell-known "Sweet William," and the mother is shown at 8. 

 The combination produced plants of great vigor, blooming freely 

 with the handsome flowers of good size, borne in small clusters 

 upon long erect slender stems, a decided improvement upon the 

 liiale parent. The blooms, uniformly of a- rich deep pink, had a 

 pleasing fragrance, but were entirely free from stamens. 



The cluster at 7 represents a hybrid between the carnation {D. 

 CaryO'pliyllus L.) and J), laiifoli/us, which has been grown for two 

 years and propagated freely by cuttings, as the hybrid produces 

 no pollen. Plants will be left in the open during the coming win- 

 ter tO' test their hardiness. 



HYBRID PHLOX. 



A union of "Perennial Blue Phlox" (PJilox dvvaricata L.) upon 

 a red variety of Phlox Drummondii Hook was secured in 1907, 

 but the blends failed to produce seed. A similar hybrid between 

 perennial and annual plants wasi obtained in 1908, when the above^ 

 named blue was worked upon the "White Star," and two plants 

 of the blend were grown in the greenhouse. Plant 1 began bloom- 

 ing in January (1909), and having flowers slightly "starred" 

 and reddish-purple in color. Plant 2 bloomed a month later and 

 also bore "star" flowers somewhat larger than those of plant 1, 

 and in color were a shade of blue, bordering upon lilac. In May 

 both plants were placed in the open together with two cuttingsi 

 from plant 1, where they continued to bloom until midsummer. 

 Repeated efforts to (1) fertilize with each plant's own pollen, pro- 

 duced in abundance; (2) breed plants 1 and 2 together, and (3) 

 unite again with either jmrent, failed, and, therefore, no seed was 

 obtained. The plants died in August, fifteen months after the 

 seeds were started.
