450 TULIPACEiE. [part n. 



ORDER CXCVL— TULIP ACE^. 



This order in the Hortus Britannicus com- 

 prises the genera Yucca, Tulipa, Fritillaria, 

 Cyclobothra, Calochortus, LiUum, Gloriosa, 

 and Erythronium (the Dog Violet) ; but Sir 

 W. J. Hooker omits Yucca, and adds Bland- 

 fordia, Hemerocallis, and Polianthes ; while 

 Dr. Lindley includes all these plants, together 

 with those comprised in Asphodelese, in the order 

 Liliacese. This last appears the most natural 

 arrangement, as all these plants have a regular 

 perianth of six segments, with six stamens, 

 and a dry or fleshy capsule of three cells, open- 

 ing by as many valves. Some of the genera 

 have more seeds than others, and some of the 

 seeds have a hard, dry, black skin, while others 

 have the skin spongy and soft. Some of the 

 genera have the flowers erect and single, as in 

 the Tulip ; in others the flowers are erect, but 

 in umbels, as in the Orange Lily ; and in 

 others they are in racemes and drooping, as in 

 the Yucca, or single and drooping, as in the 

 Fritillaria, or with the segments curved back 

 as in the Martagon Lily.
