requiiing only the usual treatment 

 of hardy annuals. 



Knight's Star. — A kind of 

 Amaryllis, considered by some 

 authors as forming a separate genus 

 called Hippeastrum. 



Kniphofia. — Asphodelece. — A 

 most striking plant, with large 

 massire flower, spikes of scarlet and 

 yellow flowers. It is a native of 

 the Cape of Good Hope ; but it will 

 flower profusely all the summer, if 

 planted in the open garden ; the 

 foliage is also ornamental, the genus 

 was formerly called Tritonia. 



KxiYES are used in gardening for 

 pruning and also for budding and 

 grafting. Pruning knives were 

 formerly characterised by hooked 

 blades ; but straight-edged blades 

 are now preferred, as making a 

 cleaner cut. The best description 

 of budding-knife has a straight 

 blade, the ujjper half of the back 

 having also a cutting edge, and the 

 handle is terminated by a rounded 

 end. Sometimes a knife is made to 

 serve as both a budding and grafting- 

 knife, as shown in fig. 32. 



KxowLTo^NiA. — Ranunculacece. 

 — Half-hardy perennial plants, 

 natives of the Cape of Good Hope, 

 nearly allied to Adonis vernalis. 

 They should be gro-uTi in peat, mixed 

 with a little loam ; and they are 

 increased by dividing the roots. 



Ko^CHiA. — ChenopodiacecE. — 

 13elvidere or Summer Cypress. — An 

 annual plant, formerly much culti- 

 vated in gardens, to gather for 

 beaupots to place in the fire-places 

 during summer ; but which now is 

 rarely seen. About a century ago 

 many plants were grown for these 

 large beaupots, but as they are now 

 no longer used, the flowers that 

 supplied them are neglected. Kochia 

 is quite hardy, and only requires 

 sowing in the open ground. 



KoLREUTE^RiA. — Sapinddicece. — 



A middle-sized deciduous tree, a 

 native of China, but quite hardy in 

 British gardens, and very ornamental

from its large variously-divided 

 foliage, and its conspicuous terminal 

 compound spikes of rich yellow 

 flowers. These are freely produced 

 in the climate of London, and are 

 often succeeded by bladdery capsules, 

 which contain seeds ; and from
