 wide ; referring to the opening of the 

 flower. Nat. ord., Blood-Roots [Haemo- 

 doracess]. Linn., S-Triandria 1-Mono- 

 f/ynia. Allied to Anigozanthos.) 



Greenhouse herbaceous plants with sword- 

 shaped leaves, from, the Cape of Good Hope. 

 Divisions, when fresh growth is commencing ; 

 seeds in a slight hotbed in March or April; 

 sandy loam and peat. Summer temp., 55 to 

 75 ; winter, 40 to 45.

DILL. Ane'thum grave' olens. Its leaves 

 and umbels are used in pickling, and 

 the former in soups and sauces. 



Soil. It may be cultivated in any 

 open compartment; but if for seed, a 

 sheltered soil, rather dry. 



Sowing. Sow immediately the seed 

 is ripe, for if kept out of the ground 

 until the spring it often is incapable of 

 germinating. If neglected until the 

 spring, sow from the close of February 

 until the commencement of May. Sow 

 in drills a foot apart, the plants to re- 

 main where sown. When of three or 

 four weeks' growth thin them to about 

 ten inches apart. -The leaves are fit 

 for gathering as wanted, and the umbels 

 about July and August. In September 

 their seed ripens, when it must be im- 

 mediately cut, and spread on a cloth to 

 dry, being very apt to be shed.

 confined in small pots in equal quantities of 

 peat, loam and pounded brick, well drained.
