40 On Acclimatizing Plants at Biel, in Bast Lothian. 



Mr. Street had adopted two methods of naturalizing plants : 

 1st, by exposing them in the open border ; 2nd, by raising 

 young plants of exotics from seeds ripened in the open air. 

 This last he considers the most effectual. 



By the first means he had induced the following to stand the 

 winter at Biel, in borders, or against walls. Verbena triphylla 

 (Aloysia citriodora), native of Chile, when planted against the 

 wall, was in some years killed to the ground, but shot up again. 

 Cneorum tricoccum, from the South of Europe, flourished 

 in a warm border. Iris Chinensis lived, but required the pro- 

 tection of a hand-glass. Buddleja globosa, native of Chile, 

 throve in a border under an east-aspected wall. Heliotropium 

 Peruvianum grew under a south wall, without protection. 

 Anchusa Italica stood the winter in the open border. Convol- 

 vulus Althagoides, of the Levant, lived and grew freely under 

 a south wall. Convolvulus Cneorum, also from the Levant, 

 succeeded equally well in a similar situation. Lonicera im- 

 plexa, from the South of Europe, stood the winter with the 

 shelter of a wall, as did Lonicera flava, a native of Carolina. 

 Linum Tauricum survived the winter, and attained a shrubby 

 habit, flowering through the whole summer. Agapanthus 

 umbellatus, from the Cape of Good Hope, stood a winter 

 without covering. Sanseviera carnea from China survived 

 the severest winters, and flowered freely in the summer. 

 Phormium tenax, from New Zealand, bore the winters, but 

 did not produce flowers. Veltheimia media, from the Cape 

 of Good Hope, stood in the open ground at a distance from 

 the wall. Alstrcemeria Pelegrina, native of Peru, in an open 

 border, in a deep rich soil, was much more luxuriant than 

 when grown in pots. Erica Mediterranea survived many
