152 YORKSHIRE NATURALISTS UNION. 



848. Ligustrum vulgare. Privet. Woods and hedges. 

 Near Sharow (introduced) ; Mackershaw (has the 

 appearance of being planted here also, as game- 

 covert) ; Hackfall, in small quantity. 



850. Vinca minor. Lesser periwinkle. Woods and banks, 

 rare. Tanfield, near Helleborns viridis ; Sawley and 

 Grantley woods (Plues). 



853. Erythraea centaurium. Centaury. Fields, not very 

 common. Thieves Gill; Quarry Moor; Mackershaw. 



857. Chlora perfoliata. Yellow wort. Fields and banks, 



local. Quarry Moor ; Whitcliffe ; in large quantity 

 (1881) in a field near Thieves Gill. 



858. Gentiana pneumonanthe. Marsh gentian. Bogs. 



Leckby Carr (Plues et al.) ; Pillmoor. 



861. G. amarella. Autumn gentian. Calcareous fields, not 



uncommon. At Quarry Moor this plant may be found 

 with four- or five-cleft calyx and corolla, and the 

 lobes of the latter sometimes equal and sometimes 

 unequal ; these points are the distinguishing features 

 between this plant and the next, but at Quarry Moor, 

 you may find four-cleft corolla with four-cleft unequal 

 calyx, four-cleft corolla with five-cleft calyx, and five- 

 cleft corolla with five-cleft regular calyx, and even 

 find two of these forms of flower (and that, forms 

 numbers one and three), actually growing on the same 

 plant. Whether these are hybrids, or whether 861 

 and 862 are extreme forms of one species, I leave it 

 to more learned botanists to settle, merely contenting 

 myself with recording facts which anyone may verify 

 for himself 



862. G. campestris. Field gentian. Wicliffe Wood (Plues) ; 



abundant in a field near Thieves' Gill. 



863. Menyanthes trifoiiata. Bog-bean. Bogs and ditches, 



local. Svvinton (Mrs. Berkeley); Marfield, Masham; 

 Leckby Carr ; Whitemere ; Hutton Moor.
