lilies. It has been necessary to make 

 many pollinations to obtain the few 

 seeds secured at The New York Bot- 

 anical Garden. Of 527 flowers care- 

 fully pollinated with pollen of H. 

 aurantiaca only two mature capsules 

 and four seeds were obtained and these 

 seeds did not germinate. From 1,763 

 flowers pollinated from H. Thunbergu 

 only nine capsules were obtained with 

 1!) seeds of which six germinated. 

 With pollen of H. citrina, 421 flowers 

 of fulva have been pollinated but only 

 eight capsules matured with 32 seeds of 

 which three germinated. There were 

 complete failures for 33 flowers polli- 

 nated from H. Dumortierii, for 121 

 flowers pollinated from H. flava, and 

 for 570 flowers pollinated from the 

 horticultural variety lutcola. _ Many 

 cross-pollinations also failed with pol- 

 len of the double-flowered varieties H. 

 fulva Kwanso and H. fulva flora-pleno. 

 The fulva clon has been unfruitful to 

 pollen of every one (51 in number) 

 of the seedlings thus far used in the 

 tests. Pollen of fourteen plants from 

 lapan and China has been used in pol- 

 linating flowers of fulva. In one com- 

 bination 105 flowers gave one capsule 

 and Ave seed, from another involving 

 101 flowers two capsules and 9 seed 

 were obtained artd from another combi- 

 nation involving 75 flowers one capsule 

 and two seed were had. 



The total number of flowers _ of 

 fulva cross-pollinated in all combina- 

 tions is 7,135. These have yielded only 

 23 mature capsules and 70 seeds of 

 which eleven have germinated. 



Fulva as a Pollen Parent 



The fulwa variety is the pollen or 

 male parent of certain hybrid seedlings 

 some of which have appeared in the 

 trade. The first of these of which 

 the writer has record were from the 

 cross //. flava X H. fulva, and were 

 produced at the Botanical Garden of the 

 University of Strasbourg, France. Six 

 hybrids, presumably of tins parentage 

 were offered for sale in a trade list 

 issued July, 1910, by Willy Miiller, 



Nocera Inferiore, Naples. Italy. 

 Through correspondence with Mr. M til- 

 ler and with Professor Karl Killian 

 of the University of Strasbourg the 

 writer learns that several hybrids were 

 obtained with fulva as the pollen pa- 

 rent, that some of these were crossed 

 with fulva as the pollen parent but that 

 during the recent war the breeding 

 was discontinued and with the death of 

 the head gardener (a Mr. Muller) and 

 of Professor Solms Laubach the rec- 

 ords of the parentage of the remain- 

 ing plants were lost. Through the 

 kindness of Professor Killian the 

 writer has received from Strasbourg 

 living plants of the H. flava X H. ful- 

 va hybrids and also of what is labelled 

 as a hybrid between H. graminea and 

 fulva. 



The hybrids between flava and fulva 

 obtained at The New York Botanical 

 Garden were first reported several 

 years ago 1,2 and again mentioned in a 

 recent publication. 3 To the present 

 time seven of these hybrids have 

 bloomed. Six other hybrid seedlings 

 have been obtained from the cross H. 

 citrina X H. fulva and two others have 

 resulted from using pollen of fulva on 

 a hybrid between H. flava and H. 

 aurantiaca. The pollen of the double- 

 flowered variety Kwanso used on a hy- 

 brid of flava X fulva has also yielded 

 two seedlings. But to obtain these 

 seventeen seedlings many flowers have 

 been pollinated. 



Other seedlings with fulva as the 

 pollen parent are to be mentioned. \ 

 recent letter from Amos Perry. In 

 lield. England, lists for sale the hybrid 

 clonal variety "George Yeld" as a 

 cross between //. citrina and //. fulva. 

 Mr. p. Y. Morrison of the Bureau of 

 Plant Industry. Washington, writes 

 that he lias seedlings obtained from 

 fulva pollen on two plants of question- 

 able identity Mr. C. Betscher of Do- 

 ver, < 'bio. states in letters receive. 1 in 

 November, 1925, that be lias used pollen 

 of fulva and flava Kwanso in securing 

 certain hybrids but whether in con- 

 trolled pollinations or not is not stated.
