as to be almost invisible, should be planted 

 in every rock-garden, where it will soon 

 become one of the welcome weeds. Other 

 kinds in cultivation are T. azoricus, T. 

 azureus, T. bracteosus, T. Zygis, T. thuri- 

 ferus, T. Chamaedrys, and T. Mastichina.

tion, of great beauty, bearing little starry 

 flowers creamy-white, the buds delicately 

 tinged with pink, a good mass of them 

 seen a few yards off having a close like- 

 ness to a wreath of foam. The young 

 leaves are tender green, spotted and 

 veined with deep red, while the older ones 

 at the base of the plant are of a rich red- 

 bronze. All the care it needs is division 

 every two years, the plants being at their 

 best the second year after division. 



TIGRIDIA (Tiger Flower}. T. 

 pavonia are bulbous plants with very 

 showy flowers, not hardy generally. 

 In some of our most southerly counties 

 they would be tolerably so in light 

 soil and a warm position, but it is 

 safer to treat them as one would the 

 gandavensis Gladioli and tender bulbs of 

 a similar nature. The annual lifting, 

 storing, and spring planting are not great 

 undertakings, and the bulbs are better for 



having the bulblets of the past season's 

 growth separated. In some warm gardens 

 the bulbs are left in the ground all the 

 winter, well protected with ashes, and 

 the results are satisfactory. Choose the 

 sunniest spot in the garden where there 

 will be no cutting winds, as these spoil the 

 great delicate flowers. Soil that is light 

 and the subsoil gravelly are the most 

 favourable conditions for these bulbs. A 

 sandy loam lightened and enriched by 

 leaf-mould is the best to ensure a strong 

 and rapid growth. The bed should have 

 at least 18 in. of good soil, and when this 

 is dug up and allowed to settle, plant the 

 bulbs the second or third week in April 

 3 in. deep and 6 in. apart, putting a little 

 sharp sand round each before filling in the 

 holes. If a dry time sets in when the 

 foliage is half grown, the bed should be 

 well watered occasionally. From about 

 midsummer onwards till September, or 

 even later, the plants will be in bloom, 

 and the stronger the plants the more 

 flowers will the sheaths yield. In October 

 the foliage generally begins to turn yellow, 

 a sign that the bulbs are ripening. Lift 

 by November, bunch them, and hang in an 

 airy shed till they are dry. 



T. PAVONIA VAR. GRANDIFLORA. Flowers, 

 larger and brighter in colour than the type as 

 introduced from native localities and figured 

 in early botanical books. Under this name I 

 would include the names speciosa, splendens* 

 coccinea, and Wheeler i. 



T. P. CONCHIFLORA. Flowers with outer 

 segments yellow, heavily blotched with red at 

 the bases, and with inner segments similarly 

 variegated. The names canariensis or conch i- 

 flora grandiflora probably represent a form 

 differing slightly as regards brilliancy of colour, 

 but it is undoubtedly a seedling form of the 

 original T. conchiflora. 



T. P. ALBA. Flowers with sepals and petals 

 of ivory whiteness, heavily blotched at the 

 bases with carmine-red 



T. P. A. IMMACULATA. This new variety 

 is a sport from the ordinary white-flowered 

 form of this beautiful summer-flowering bulb. 

 Its name inimaculata (without spots) has been 

 given to it in allusion to the uniform snowy 

 white colour of the flowers, which are in the 

 interior entirely devoid of the conspicuous spots 

 characteristic of the other varieties. 



T. P. LILACEA. Flowers with rosy carmine 

 sepals and petals, the bases variegated with 

 white, a cross between T. Pavonia and 7". 

 Pavonia alba. 



T. P. ROSEA. Flowers with rose-coloured 

 sepals and petals, the bases variegated with 

 yellow, a cross between T. Pavonia and 

 conchiflora. 



These comprise the varieties and synonyms 

 of the true Tigridias, unless the new T. 

 Pringlei belongs to this section. The Bea-
