orientalis varieties, especially the single ones, and early 

 Tulips. 



Besides the foregoing, there is a multitude of other bulbous- 

 rooted plants, flowering from the spring onwards, till late in 

 autumn. Sternbergia lutea, Colchicum autumnale, and seve- 

 ral species of Crocus, are some of the later flowering kinds. 

 The magnificent genera Lilium and Gladiolus are essentially 

 summer-flowering plants. Lilium is distinguished from its 

 allies by its scaly, not solid 5 bulbs, a distinction to be re- 

 membered, as they suffer much more from exposure than do 

 the solid bulbs, or corms, as they are technically termed. A few 

 other genera commonly seen are Ornithogalum, Fritillaria 

 (Crown Imperial), Iris Xiphium and Xiphioides, Crinum 

 Capense, Eucomis punctata, Camassia esculenta. Pancratium 

 maritimum, P. lUyricum, and Amaryllis Belladonna, are less 

 frequently seen, but equally deserving of a place in a large 

 garden. Most of the preceding have solid bulbous roots, but 

 there are many allied genera with fascicled fleshy roots, or 

 creeping rhizomes, as Anthericum, Funkia, Convallaria, Aspho- 

 delus, HemerocaUis, and the majority of the species of Iris. 

 Another set of plants, whose roots are usually, in some cases, 

 and invariably in others, stored away for a part of the year, 

 includes the genera Dahlia, Canna, Kanunculus, Anemone, 

 Oxalis, Tropseolum, Begonia, and Cyclamen , Jfor further in- 

 formation respecting these plants and their allies, we refer our 

 readers to the orders LiliaceaB, Amaryllidaceae, Iridacese, and 

 Melanthaceas. Several other genera, chiefly frorn, South 

 Africa, and containing many very handsome species, will be 

 found described in the first part of this work. Tigridia, Ixia, 

 Sparaxis, Babiana, and Witsenia, include some of the showiest 

 species, but they are all more or Jess tender. 



Aquatic and Marsh Herbs. Almost every garden of any 

 pretensions has its watercourse or lake, either natural or arti- 

 ficial, or in lieu thereof some ornainenta) basins, tanks, or 

 fountains. To fill these there is no lack of hardy subjects, 

 suitable either for the small fountain-basin, or for the spacious 

 lake or stream. For a small tank or basin we have such 

 plants as Nymphsea pygmaea, Nuphar pumila, Calla palustris, 

 Hydrocharis Morsus-ranae, Utricularia vulgaris, Hippuris 

 vulgaris (Horsetail), Limnanthemum nymphasoides, Stratiotes 

 abides (Water-Soldier), Aponogeton distachyus, and Alisma 

 natans ; to which might be added Lemna minor and other
