White Campion ( I.\(hnis alha, Mill.) 



This |il.iiu has hfcn met with in .Xcciliiliic hcds at Fife. It is 

 foiiiul to ila\ in the Tfinpcralc Zone in I'Airopc, N. Africa, Siberia, 

 Western Asia. It has been introduced in the United States. 



Ill ('. I'cit I'lritain it is absent from Worcester, and in ,S. Wales 

 in Radnor. In X. Wales it occurs only in Carnar\(in, 1 )enbi;4"h, 

 Mint, and An^lesea. It is absent from Mid Lanes, Isle of .Man, 

 Peebles, Selkirk, I\o.\lun-L;h, and in I'.. Ilinhlands in .Mid I'erlh. in 

 W. Highlands in Main i\rL;)le, .Mid and North Flnides, Caithness,

The night-ilowering or Whit(; Cam[)ion is undoubtedly a follower 

 of cultivation, foi' it is speciall)- characteristic of the cornfield, where 

 it is abiuulant and \vell-established. Not infre<|uently it will be found 

 in place of its allied species, the Red Campion, lining the hedgerow 

 in a district where corn is, or has been, largely grown, but it is on 

 arable land that it is most conspicuous and at home. 



This is a tall, smooth or hairy, graceful, slender [jlant, with egg- 

 shaped, narrowly" elliptical lea\'es, \er\' similar in habit to the ilcd 

 Campion, usually growing in scattered groups in cornfields or hedge- 

 rows, not in massive clumps like the latter. It is slightly clammy. 



The flowers are white, and open completely at night, from si.\ 

 o'clock till nine next morning, when they" droop, e.xcept in dull w rather, 

 when thev are fragrant. The petals are divided halfway into two parts, 

 the lobes approaching and broad, crowned, and the caly.x teeth are long 

 and linear, narrowly elliptical. The capsule is conical with lo erect 

 straight teeth, and no divisions. The seeds are small and numerous. 



The plants are ditecious, stamens and pistils occurring on different 

 jjlants as a rule, or there may be three forms — male, female, and 

 bise.xual. 



White Camjiion grows 2 ft. high, and is in flower in June and 

 lulv. It is perennial and propagated by dixision. 



In fertile pistillate or female flowers the honey glands are placed 

 20-25 mm. from the entrance in the fleshy part of the ovary, in barren 

 staminate or male flowers at 15-1S mm. The upper part of the caly.K 

 in Ixjth forms is narrower. It is necessary for the insect to force this 

 narrow passage with its head, and honey cannot be reached e.xcept 

 by insects with a proboscis 15-20 mm. long. The flowers open in the
