readily increased by dividing the bladder-like vesicles, or by 

 taking off the offsets which are spontaneously produced. The 

 Pinguiculas seed freely, and the seeds germinate very readily 

 on any moist surface, and often appear in large quantities from 

 self-sown seed, in the cool pit or frame where the plants have 

 been grown. 



THE LILY FAMILY (Liliacece). 



Some of the most beautiful of all bulbous plants are included 

 in this order, the true Lilies being perhaps the most ornamental 

 from a cultivator's point of view, being represented in our gar- 

 dens by some forty or fifty species, and numerous forms all 

 more or less beautiful. Naturally they are distributed widely 

 in South Europe, North America and California, Japan, and 

 on the mountains of North and South India. The most useful 

 Lily- worts are the Alliums. A. ascalonicum, or Shallot, was 

 brought from Palestine before 1546. A. cepa, the Onion, has 

 long been cultivated, and its native country, like that of many 

 other ancient food-plants, is unknown, but it probably originated 

 in the East. A. fistulosum, or Welsh Onion, is a native of 

 Siberia, and was introduced prior to 1629. A. porrum, the 

 Leek, is a Swiss plant, first grown in this country about 1562. 

 A. schcznoprasiim, or Chives, is a British plant. A. sativum, 

 Garlic, was introduced from Sicily before 1548; while A. scoro- 

 doprasum, Rocambole, is a native of Denmark, introduced 

 before 1596. Dr Royle is of opinion that the Leeks, Garlic, 

 and Onion of to-day are the same plants mentioned in the 

 Bible under their respective names (Num. xi. 5). - Tulips, 

 Fritillarias, Scillas, Ornithogalums, &c., are widely distributed 

 in Europe. Yuccas are principally American ; Aloes come 

 principally from the Cape ; and the Hyacinth seems to have 

 been introduced from the Levant previous to 1529. Nearly 

 all Liliaceous plants seed freely ; others produce little bulbils 

 on the flower-stem, instead of bearing seed (ex. Potato-Onion), 

 and others are readily multiplied by dividing the bulbs or off- 

 sets. All the robust-growing Lilies, with thick scaly bulbs, 

 may be propagated by stripping off the scales carefully, and 

 planting them for cuttings, as is done with Echeveria leaves. 

 Sow the seeds of tender species in a gentle bottom-heat as soon 

 as gathered, or in the spring. The seeds of hardy species may 

 be sown in the open air in March or April. The rarer kinds, 

 however, are best sown in pans placed in a cool frame. All the 

 ornamental species of Lily-worts having bulbous or fascicled
