OUR NATIVE PLANTS. 161 



mental genus of several species. S. purpurea^ which grows far- 

 ther north than an}- other, is a pretty plant with dark purple flow- 

 ers. This plant is perfectly hard}', and succeeds with the same 

 treatment as has been recommended for bog plants. S. Jlava has 

 erect trumpet-like leaves, sometimes over three feet high, and Ig-rge 

 yellow flowers ; it is hardy if treated like the foregoing and cov- 

 ered up in the autumn. S. Drummondi attains the same height, 

 but its pitchers are beautifully mottled and striped with white and 

 purple, while the flowers are red. S. undidata is only a variety' of 

 S. Drummondi, with the half-curved lid. S. psittacina has reclin- 

 ing pitchers of green and white, and dark purple flowers. S. ru- 

 bra and S. Sweetii are much alike ; they have small narrow pitch- 

 ers and red flowers. S. variolaris has sub-erect inflated pitchers, 

 and yellow flowers. 



The last named six kinds must be grown in a cool greenhouse, 

 in pots filled with rotten leaves and sphagnum moss. Of this genus 

 more than a dozen hybrids have been produced in English gardens 

 by crossing the different species, and later the hybrids themselves. 



The Drosera, or Sundew, is represented by several small plants 

 with white flowers. The}' can be grown with good success in the 

 same way as bog plants. D. rotundifolia, D. Jiliformis, and D. 

 longifolia are among the hardiest and best adapted for culture. 



Darliyigtonia Californica is a very beautiful plant, nearl}' rela- 

 ted to the Sarracenias. It has pitchers over two feet in height, 

 terminating in a kind of hood, with two appendages. The flower 

 is large, of 3'ellow and purple color. The culture is the same as 

 directed for greenhouse Sarracenias. 



Next we have the 



Succulent Plants. — In some portions of the southwestern 

 part of this country large tracts of laud, consisting of very poor 

 sand}' soil, and at times without any rain for several months, 

 would be quite destitute of any vegetation if it were not for this 

 class of plants. On such a soil is their home, and there they flour- 

 ish, being furnished by all-providing Nature with thick and succu- 

 lent stems and leaves, which serve them as storehouses from 

 wMch to draw their subsistence in the dry season. Their form 

 and structure are quite striking and ornamental, and besides they 

 have very large, beautifully colored flowers, which I regret to say 

 are of short duration. 



They are of very easy culture, the main point being to avoid
