98 LEGUMINOS^. 



A. Onobrychis {Purple- spiked Milk- Vetch). — This is a taller 

 and more elegant plant than either of the preceding, reaching 

 the height of a foot or 1 8 inches. The flowers are purple, in dense 

 spikes, and are produced in June, July, and August. It is very 

 suitable for the mixed border, and is also desirable for the rock- 

 work. Native of Austria and near Provence. 



A. purpureas {Purple-headed Milk- Vetch). — This species is 

 nearly related to leo?itinus, but differs from it mainly so far as 

 our object is concerned in the colour of the flowers, which are 

 bright purple, and from Onobrychis, to which also it is related, 

 in the form of the heads of flowers, which are in close globose 

 heads, not spikes. Native of the Alps of Provence, Nice, and 

 the south Tyrol. Flowers in June, July, and August, and 

 suitable alike for the border and rockwork. 



Baptisia. — This is a genus of North American hardy peren- 

 nials, comprising few species, and of which only two or three 

 are in cultivation; but as they are in very close resemblance to 

 each other, it is the less to be regretted that we have only few 

 to commend. They are plants of most easy culture, thriving 

 in any soil if moderately well drained. They are easily propa- 

 gated by division and by seed, which they ripen freely in this 

 country. They are only suitable for culture in the mixed 

 border, being rather too gross in habit for the rockwork ; and 

 they might be used on sunny banks in half-kept parts of parks 

 and grounds, and on the margins of shrubberies where rabbits 

 do not abound. 



B. alba ( White ^.)— This plant grows erect about 2 or 2^ 

 feet high. The leaves clothe the stems rather densely, are 

 dark green and trifoliate; the leaflets are oval. The flowers are 

 white, appearing in small but numerous racemes on the upper 

 parts of the stems. They appear in summer, and last about 

 two months. 



B. australis {Blue B.) — This is very near in character to the 

 last. The height and habit are the same. The leaflets are, 

 however, lance-shaped; and che more important floricultural 

 distinction of blue flowers renders this at once desirable as a 

 companion to the other, especially as they flower, and the 

 flowers endure, about the same time. 



B. tinctoria {Dyer'sB.) — This is very distinct from the others, 

 being more dwarf and slender. The leaves are also trifoliate, 

 but the leaflets are roundish, and clothe the stems more sparingly. 

 The flowers are yellow, in small loose racemes at the tops of 

 the stems, and appear about the same time as the others, but 

 last fully a month longer. Height about i j^ foot. 



Coronilla. — This is a small family, containing a fevv^ species
