and waste ground in various parts 

 of England. It has narrow grey- 

 green leaves 6 to 10 ins. long, and 

 bright yellow sweet-scented flowers 

 on stems 1 to 2 ft. high. {Bot. Mag. 

 t. 1202; Rev. Hort. t. 165.) T. 

 Biebersteiniana, T. fragrans, and 

 T. strangidata are considered to be 

 forms or geographical variations of 

 T. si/lvestris. 



T. triphylla. — A native of Central 

 Asia, having three to four narrow 

 sickle-shaped leaves, and bright 

 citron-yellow flowers tinted with 

 green on the outside (Bot. Mag. t. 

 6459 ; Garten ff. t. 942). The varietj- 

 Hoeltzeri has the three outer petals 

 yellow and purple. (Gartenjf. t. 

 1144, f. 3-4, A. B.). 



T. Tubergeniana. — A native of 

 Bokhara, having large rich orange- 

 crimson flowers with a dark blotch 

 at the base of the very broad and 

 somewhat sharply-pointed segments 

 (Gard. Chron. 1904, xxxv. 358, f . ; 

 Flora and Sylva, April 1905). 



T. turkestanlca. — A native of 

 Turkestan, closely related to T. 

 hijlora, having lance-shaped curved 

 leaves and often two white flowers 

 about li ins. across, with a yellow 

 centre (Gartenrf. t. 1050, f. 2). 



T. undvilatifolia. — A handsome 

 Tulip from Asia Minor, having grey- 

 green narrow lance-shaped wa^-y 

 leaves, and scapes 6 to 9 ins. high, 

 with a bright crimson bell-shaped 

 flower washed with gi-een outside, 

 and having a black centre with a 

 yellow ring. Some forms have 

 yellow centres and flatter, less Avavj- 

 leaves. (Bot. Mag. t. 6308.) 



T. 11 ni flora. — A Tulip from the 

 Altai Mountains, having pale yellow 

 flowers borne on slender scapes, about 

 the middle of which are a pair of 

 lance-shaped leaves (Gartenff. t. 906, 

 f. 25; Siv. Br. Fl. Gard. Sen: ii. 

 t. 336). 



T. violacea. — A Persian species 

 near T. Clusianu, but with narrower 

 leaves and smaller flowers of a 

 brilliant deep carmine with a black 

 base, and borne on stems about 6 

 ins. high. It is one of the first 

 Tulips to flower in the open. (Bot. 

 Mag. t. 7440.) 



T. virldiflora. — A curious form of 

 T. Gesnen'ana, having large greenish 

 or greenish-yellow flowers striped 

 and banded with yellow. It is 

 supposed to be the parent of the 

 Parrot or Dragon Tulips. 



T. vitellina. — This is considered 

 to be a hybrid between T. Gesneriana 

 and T. suaveolens. It has large 

 flowers of a delicate whitish or 

 butter-like yellow. (Garden, 1889, 

 ii. t. 730.) 



T. Wilsoniana. — A Persian species 

 with wavy red-edged leaves, verj' 

 bright red flowers without a basal 

 blotch or only a very small one, and 

 red filaments with golden anthers. 

 The bulbs bear a mass of protruding 

 woolly hairs. (Gard. Chron. 1901, 

 xxis. 327, f. 121.) 



Diseases. — Tulips are sometimes 

 afliicted with a fungus (Sderotinia 

 parasitica) which forms olive brown 

 velvetj' patches on the stems, leaves, 

 and flowers. Diseased plants should 

 be taken up and burned at once, and 

 the soil should be well dressed with 

 slaked lime and flowers of sulphur 

 to prevent the spread of the fungus. 



TUPISTRA (tiqn's, a mallet ; in 

 reference to the form of the stigma). 

 Xat. Ord. Liliaceffi. — A small genus 

 closely related to Aspidistra, consist- 

 ing of hothouse herbaceous perennials, 

 having thickish or tuberous root- 

 stocks, large leaves, and stalkless 

 flowers in dense cylindrical spikes. 

 All the species grow in rich loamy 

 soil, and require plenty of heat and 

 moisture during growth. The winter
