DESCRIPTION OF PLATES. 



Plate I. Frontispiece. — Seedling lilies in bloom. A. — Lilium longiflorv/m X L. har- 

 risii. B. — Liliumharrisii X L. longiflorum, showing large flower. Photo- 

 graphed April 16, 1902, six months anil thirteen days after germinating. 

 II. Fig. 1. — Lilium longiflorum, tall-growing variety from Japan, showing the 

 vertical position assumed by the ovaries after fertilization. Fig. 2. — ■ 

 Lilium longiflorum, low-growing variety from Japan, with long, broad 

 leaves. The capsules show the progress made at a period of three weeks 

 after pollination. Fig. 3. — Lilium longiflorum, tall-growing variety from 

 Japan, with long and broad leaves along the entire length of the stem. 



III. Capsules and seeds of Lilium harrisii X L. longiflorum. Flowers polli- 



nated April 3; seeds ripe June 14, 1901. 



IV. Fig. 1. — Lilium harrisii X Lj. longiflorum seedlings in 2-inch pots. Seeds 



sown June 26, 1901, germinated October 3, potted October 28, pho- 

 tographed November 9, 1901. Fig. 2. — Lilium harrisii X Lj. longiflorum 

 seedlings in 2J-inch pots ten weeks after germination. 



V. Fig. 1. — Lilium harrisii X L. longiflorum, showing size of bulb February 16, 

 1902, eighteen weeks after germination. Fig. 2. — Seedling bulbs of L. 

 harrisii X L. longiflorum. The bulb to the right measured 6 inches in 

 circumference. These bulbs were grown from the seed within ten 

 months. 



VI. Diseased Bermuda lily bulbs. A. — Cross section through a diseased bulb 

 that began to grow and then died. The tissue was eaten out by the 

 ludb mites. B. — Cross section through a bulb that failed to grow. 

 The bud was eaten out by mites. 



VII. Germination of Lilium longiflorum. 1. Sprouting of the seed. 2. An older 

 stage, where the cotyledon shows the bending, while the apex remains 

 closed in the seed absorbing the endosperm. 3. Still older. 4. The 

 cotyledon has now unfolded itself, raising the attached seed high above 

 the level of the ground. 5. The first leaf V is developed while the 

 cotyledon is as above. 6. The seed has dropped and three leaves are 

 now developed; also two secondary roots. The roots show wrinklings 

 above, indicating their contractile power in drawing the bulblet deeper 

 and deeper into the soil.
