blue. Sepals 5, the upper one produced downwards into a free 
spur. Petals unequal, 5, or by abortion fewer, often fringed 
or bearded at the base. Stamens 8, free, all antheriferous. 
Fruit of usually three fleshy indehiscent 1l-seeded carpels ; 
seeds exalbuminous. About thirty-five species are known, all 
inhabiting South America. The name is said to be derived 
from tpé7aiov, a trophy. The tubers of some species are used 
as an article of diet in Peru. 
Annual Species. 
1. LT. adinenm, syn. T. peregrinum.—This is commonly 
known as the Canary Creeper, and sometimes named 7. 
Canariénse ; but it isa native of America only. It is very 
distinct, and readily distinguished by its slender stems, 3- to 5- 
lobed leaves, and bright canary-yellow flowers with narrow petals. 
2. T. mcjus (fig. 60). Taller Nasturtium or Indian Cress.— 
This is the common tall-growing kind, the carpels of which are

used as a substitute for capers. In the typical plant the flowers 
are yellow, but there are crimson, scarlet, orange, and striped 
single varieties, and also double-flowered forms, in cultivation. 
3. T. avinus. Smaller Nasturtium.—Similar to the last, 
of dwarfer growth, with smaller flowers of a more reddish- 
orange colour. The varieties of this are very numerous and 
beautiful. The carpels of this are said to be superior for 
pickling to those of the preceding species.
