ble because all its members ma}' be cultivated out of doors. L. 

 Philadt'lphicn.m^ which is found on hills, grows two feet in height, 

 bearing large and erect orange-red flowers in July. Of similar 

 habit is L. Catesbcni, but the flowers are larger and more 

 open, of red and yellow color. L. Canadense grows from two to 

 four feet high, and bears several large nodding flowers, either red 

 or yellow, with inimerous spots. L. Columhianum grows al)out 

 three feet in height, and has smaller nodding flowers of bright deep 

 orange color. L. Hvmboldtii is one of the most beautiful species, 

 attaining four or five foet in height, and bearing numerous very 

 large nodding flowers. The inner portion is red, while the ends 

 of the petals are deep yellow. L. parvum has pretty, erect flowers 

 of deep yellow color and marked with numerous small spots; it 

 grows from two to three feet in height. L. Wasldngtonianum has 

 stems from four to eight feet high, and large sub-erect flowers, 

 white at first, but turning to deep rose and dotted. This beautiful 

 plant has the further great merit of being very fragrant. Of the 

 same habit is L. rubescens, which is sometimes considered only a 

 variety of the former ; it has nearly erect flowers of beautiful lilac 

 color, changing to purple. L. Parryi grows about three feet in 

 height, and bears several large horizontal flowers of primrose yel- 

 low color, slightly spotted. The very rare L. Grayi has stems two 

 feet in height, with several horizontal flowers, red with large dark 

 purple spots. The rather common but not less beautiful L. super- 

 bum grows as high as six feet, and sometimes produces even as many 

 as thirty of its large, nodding, red and yellow flowers, which vary 

 greatly in their markings. L. px^t'dalinum is a showj' plant, grow- 

 ing from four to eight feet in height, and bearing large spikes of 

 its ample and nodding blossoms, which are yellow and red. L. 

 marilimum is said to have horizontal, bright rod flowers, but I 

 have never seen more of it than a painting. These last-named three 

 species are an exception, as regards culture, to bulbous plants in 

 general, because they require to be grown in wet ground ; which 

 is quite contrary to the rule for other plants of this class. 



The Eryihroniimi, or Dog's-tooth Violet, is a genus of pretty an(i 

 neat plants with variegated foliage and ample flowers. E. Amer- 

 icanxim is quite common in our woods ; it has bright yellow 

 flowers. E. albidum has white flowers, while E. 2n'opulla7is is 

 bright rose. E. grandijlorum bears several flowers varying in 

 color from yellow to pure white, or tinted with purple. E. pur-
