MOUNTAIN FLOWERS 21 



This common little white-flowered plant grows all over the 

 world in temperate zones and at various altitudes. Its tiny 

 heart-shaped seed-purses have amused the children of many 

 countries. It is closely related to Candytuft, to which it 

 bears a strong resemblance. 



PENNY-CRESS 



Thlaspi arvense. Mustard Family 



Stems : erect, glabrous. Leaves : petioled, oblanceolate, dentate ; stem- 

 leaves oblong. Flowers: white, pedicels spreading or curved upward. 

 Fruit: pods nearly orbicular when ripe, broad, very flat, notched at the 

 apex, in long racemes ; seeds rugose. Not indigenous. 



Penny-cress very nearly resembles Shepherd's Purse, and 

 the easiest way to distinguish between the two plants is to 

 note that while the seed-pods of the latter are triangular in 

 shape, those of the Penny-cress are nearly round, both being 

 notched at the top. Then, also, the leaves differ : those of the 

 Shepherd's Purse are deeply cut, and those of the Penny- 

 cress are only slightly toothed. 



CANADA VIOLET 



Viola Canadensis. Violet Family 



Stems: glabrous, six inches to two feet high. Leaves: cordate, pointed, 

 serrate; stipules entire. Flowers: petals white, tinged and veined with 

 purple, sometimes nearly mauve-pink ; spur very short ; stigma beakless. 



One of the most beautiful of the many violets that grow in 

 the mountains, its lovely white petals, purple-shaded on the 

 back, giving forth a delicate fragrance, and its tall leafy stems 

 bearing aloft many blossoms. Usually it is found in the moist 

 mossy woods, where it flourishes luxuriantly ; but it also grows 

 on the open alpine meadows, though here its stalks are not so 

 tall nor its flowers so large as they are in the shade of the 

 pines and firs. The Canada Violet continues to bloom from 

 June until September.
