190 NIGELLA 



NiGELLA — continued. 



N. hispan'ica has claret and white flowers, and not 

 quite as tall as the first-mentioned species. 

 Spain, 1629. There is a purple variety of this 

 called atropurpui^ea. 



N. orienta'lis. With pale yellow flowers, about \\ 

 ft. high. Syria, 1699. 



N. sati'va has pale yellow flowers, but not sur- 

 rounded by leaves like the others. It is 

 cultivated abroad for its aromatic seeds. 

 About 11 ft. high. Egypt, 1548. 



As the seedlings do not stand transplanting 

 well, sow the seeds ^ in. deep in March where they 

 are to grow. Thin out 6 ins. apart each way when 

 quite young. 



Night- Scented Stock. See Hesperis tristis. 



Nola'na — Chilian Belljiower (from late Latin nola, a 

 little bell, for a dog). Nat. Ord. Convolvulacece. 

 (Lindley's Order Nolanacew.) 



These little annuals are deserving of more 

 popular attention, for they seem to be rarely 

 grown. Though dwarf trailing and spreading 

 herbs, and most suitable for a rockery, the flowers 

 are quite large, about 2 ins. across, the shape of the 

 better known Convolvulus. Being maritime natives 

 of Chili and Peru they require a very sunny aspect. 

 N. atriplicifo'lia. 4 ins. high, with showy lavender 



blue flowers with yellow and white centre. 



Peru, 1834. There is a white form named 



alba.
