2. C. latifolia (fig. 34).—A tall-growing Spanish species with 
purple flowers, appearing in June. It inhabits swampy places. 
3. C. trifolia.—A distinct little plant, about 9 inches high, 
with glabrous trifoliate leaves and dense corymbs of small pure 
white flowers. A native of Switzerland, flowering in Spring. 
5. LUNARIA. 
Biennial or perennial pilose herbs with erect branching 
stems and cordate simple dentate petiolate leaves and ter- 
minal racemes of purple flowers. This genus is remarkable 
for the oval or oblong compressed stipitate siliquas, whose 
transparent silvery partition is persistent after the valves have 
fallen away. Only two species are known; natives of Central 
Europe and Western Asia. Name from luna, the moon, the 
shape of the seed-vessel. 
1. L. biénnis, syn. L. dnnua (fig. 35).—This is the plant 
familiarly known as Honesty. <A biennial, from 2 to 3 feet 
high, with large purplish-violet flowers. There is also a white 
variety. May to July. 
2. L. rediviva.—A perennial species, not so pretty as the 
above, with smaller pale blue flowers and a smaller seed- 
pouch. : 
6. AUBRIETIA. 
A genus of small dwarf trailing hairy herbs with small 
entire or toothed leaves and rather large purple flowers. In 
character it is very close to Alis- 
sum, with the exception of the 
lateral sepals being saccate at the 
base. There are about six species 
known, from the Mediterranean 
region. Named in honour of a 
French botanical draughtsman. 
1. A. deltoidea (fig. 36).— 
There are several varieties of 
this, differing in the size and 
brilliancy of their flowers from the 
typical plant. The best one in 
cultivation is that named Camy- 
bélliz, which is much larger in the 
flower, and apparently a freer 
bloomer. A. purpirea, of larger stature, with larger deeper 
violet flowers, is held by some to be a distinct species, including 
Campbéllii, grandiflora,and Gra&ca, They all flower in Spring.
