EVENING PRIMROSES AND GODETIAS 215 
Many others have been introduced during the present century, among 
them the species formerly separated under the name of Godetia, and 
which are still known as such in gardens. Of these, @. Romanzovii was 
the first, from North America in 1817, followed by @. acaulis from Chili 
in 1821, @. amena from North-West America in 1826, E. vinosa from 
_ California in 1835, and @ Whitneyi from California in 1870. The 
principal reasons for formerly separating them were found in the fact 
that the Evening Primroses opened their flowers only after the sun had 
gone down, and were yellow or white in colour; whereas the Godetias 
were open all day, and were of various shades and combinations of rose 
and purple as well as white. These grounds of separation are now 
regarded as insufficient. The following species are perennial, except 
where otherwise stated. 
CENOTHERA ACAULIS (stemless). Dwarf, 6 inches high. 
Leaves all radical, forming a rosette, deeply cut in a pinnate 
manner. Flowers large, white, turning red as they fade; May to 
September. (Godetia acaulis.) 
: CE. AM@NA (pleasing). Stem semi-erect, branching, 1 to 2 feet. 
Leaves slender, lance-shaped. Flowers rosy, each petal with a crimson 
spot; May to September. Annual. Plate 105 (Godetia amena). The 
var. rubicunda has erect stems, 2 fect high, with lilac-purple flowers; it 
_ is one of the parents of the numerous garden Godetias. 
CE. BIENNIS (biennial). Zhe Evening Primrose. Stem _ erect, 
branched, 2 to 5 feet. Radical leaves broadly lance-shaped, stem-leaves 
more slender, faintly toothed and finely downy, especially the midrib. 
Flowers large, pale yellow, fragrant; June to October. Biennial. The 
var. grandiflora has much larger flowers than the type. 
CH. CALIFORNICA (Californian). Rootstock creeping, horizontal; 
stems 2 feet. Flowers large, fragrant, varying white to pale pink with 
yellow centre; July. 
CH. ExIMIA (choice). Stems 9 to 12 inches high. Leaves lance- 
shaped, downy, deeply but irregularly toothed. Flowers very large, 
white; July. Native of Rocky Mountains (introduced 1870). 
CE. GLAUCA (glaucous). Stem reclining, 1 to 2 feet high. Leaves 
smooth, oval, slightly toothed. Flowers large, pale yellow; June to 
October. Introduced from North America (1812). The var. Fraseri 
Principal Species. 
_ has deeper yellow flowers and rich dark green foliage. It blooms 
profusely throughout the summer, and is one of the best garden varieties. 
__ GE. Linearis (very narrow). Stem slender, branched, 12 to 18 
es. Leaves very slender, lance-shaped, remotely toothed. Flowers 
yellow, slightly fragrant; June to September. North America (1822).
