Crucifenz Cardamine. 47 



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. LUJSTARIA. 



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. biennis, 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. redivlva. 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 Alys- 

 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. deltoldea (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 Camp- 

 bellii, which is much larger in the 

 flower, and apparently a freer Fig " 36 ' Aubrietia deltoidea ' ( * nat size -> 

 bloomer. A. purpurea, of larger stature, with larger deeper 

 violet flowers, is held by some to be a distinct species, including 

 Campbellii., grandiflora, and Grceca. They all flower in Spring.
