On the Cultivation of Rare Plants. 



Hyalis Marginifolia. MSS. Ixia lancea. Jacq. Ic. v. 2. 

 t. 281.— Collect. Suppl.p. 13. 



I never observed the leaves of this plant, during six years 

 that it was in my collection, to lose their cartilaginous mar- 

 gin : but in seedlings, or very weak plants, the leaves are 

 sometimes so narrow, as to be hardly distinguishable from 

 those of a Trichonema. 



Hyalis Aulica. MSS. Ixia aulica. Dryand. in Hort. 

 Kew. ed. 2. v. 1. p. 66. Ixia capillaris y. Ker in Bot. Mag. 

 n. 1013. cum Ic. 



This species was lost both at Kew and Clapham, soon after 

 it was introduced, for want of more heat, I believe, in sum- 

 mer, and not winter. A single bulb only should be planted 

 in each pot; for the fibres of one, that I saw turned out 

 rotten, had formed a strong bag of net- work just the shape of 

 the pot, like those of many Watsonias. 



Hyalis Longiflora. MSS. Ixia longiflora. Curt, in Bot. 

 Mag. n. 256. cum Ic. Gladiolus longiflorus. Linn. Suppl. p. 96. 



I have a specimen of this plant gathered at Chelsea in the 

 year 1758 ; and it will endure so much cold in winter, that by 

 a little management, it might perhaps, with many other 

 bulbs from the higher districts of the Cape, be cultivated in 

 our borders, like A nemonies and Ranunculusses, not planting 

 them till January or the beginning of February, as the 

 weather might allow. If any one should make the experi- 

 ment, it would not be adviseable to begin with bulbs fresh 

 imported, but such as have been already here some years. 

 This species increases most abundantly by sending out 

 strings, which, like those of Crocus Nudifiorus, terminate in 

 a bulb.
