85. Iris acoroides (Spach) xI. germanica (L.) and varieties. 
Object.—To obtain for water culture Irises of large size and variously 
coloured flowers. 
1896. Twelve flowers treated. Result nil. 
1897. Ten flowers treated. Result nil. 
1899. ‘Ten flowers treated. Result nil. 
86. Iris pseudacorus (L.) x Iris germanica (L.) and varieties. 
Object.—To obtain for water culture Irises of varied colours, like the 
Tris germanica. 
1896. Fifteen flowers treated. Five had set, but the fruits were 
destroyed by a malicious gardener. 
1897. Fifty flowers treated. Nine fruits set, three have been 
destroyed by visitors, six have given seed, which when sown have only 
so far yielded yellow flowers, which leads to the supposition that the 
operation was badly done. 
1899. Twenty-five flowers treated. Three fruits set (July 4, 1899). 
87. Iris pseudacorus (L.) x Iris Delavayi (Franch.). 
Object.— To vary the colours of Iris pseudacorus. Iris Delavayi, 
introduced by the Muséum in 1886, is an aquatic species with fine blue 
flowers. Habitat Yunnan. 
1898. Five flowers treated. Result nil. 
1899. Five flowers treated. One fruit set, looks good. 
88. Iris Delavayi (Franch.) x Iris aurea (Link). 
1899. Two flowers treated. One fruit set, but doubtful. 
89. Nicotiana Tabacum (L.) x Nicotiana affinis (Hort.). 
Object.—To obtain in Nicotiana Tabacum large scented flowers like 
those of N. affinis. The plant thus transformed would be probably 
very ornamental on account of its height and good habit. 
From 1887 to 1898 attempts have been made each year without 
result, although we have several times obtained capsules. The seeds 
have never come up. Every year some ten to twenty flowers have been 
treated. 
90. Nicotiana affinis (Hort.) x Nicotiana Tabacum (L.). 
Object.—To vary the Nicotiana affinis. 
From 1887 to 1898 numerous attempts, but no results. Some ovaries 
have swollen, but the seed was bad and has not come up. 
91. Nicotiana Tabacum (L.) x Datura meteloides (D.C.). 
1889. Ten flowers treated. Only one capsule gathered which con- 
tained seeds incompletely developed, and incapable of germinating. They 
have given no results. 
92. Nicotiana Tabaeum (L.) x Petunia nyctaginiflora (Juss.). 
1889. ‘Twenty flowers treated. Thirteen capsules gathered. Seed 
did not come up. 
1890. ‘Ten flowers treated. Results nil.
