ZAUSCHNERIA (named for a professor of natural 

 history at Prague). Onagrdcese. Low perennials, some 

 of them subshrubby, few of them used in the flower- 

 garden. 



Leaves, -the lowest opposite, others alternate: fls. 

 racemose, large, scarlet, fuchsia-like; calyx-tube globose, 

 inflated just above the ovary, then becoming funnel- 

 form, 4-lobed, bearing 8 small scales within; petals 4, 

 obcordate, or deeply cleft; stamens 8: caps, slender- 

 fusiform, obtusely 4-angled, 4-valved, many-seeded.

 with the fl. of a fuchsia and the fr. of an epilobium: 

 height %-2 ft.: Ivs. linear to oblong, }/z-\}/2 in. long, 

 pubescent or tomentose: fls. scarlet or vermilion, the 

 trumpet-shaped calyx 1J^ in long; calyx-lobes ovate; 

 petals obcordate, spreading: fr. 4-valved, imperfectly 4- 

 loculed. Calif. P.M. 15:195. F. 1847-8:241. Gn. 31: 

 28 and p. 29. R.H. 1849:141. Var. splendens, Hort., 

 is perhaps a little more luxuriant plant, otherwise not 

 differing from the type. Var. latifolia, Hook. Often 

 nearly glabrous: Ivs. broad-ovate to ovate-lanceolate, 

 markedly feather-veined. B.M. 4493. F.S. 4:404. 

 Varieties have been made based on linear, lanceolate, or 

 ovate Ivs., but they run into one another. The plants 

 also vary from glabrous and pubescent to tomentose. 

 As a bedding-plant it has been occasionally used for 

 novelty effects by European gardeners. To overcome 

 its thin and leggy habit, it is well to set the plants 

 rather close and pinch out the young shoots until com- 

 pact bushes are secured. The plant is sometimes grown 

 in pots for greenhouse decoration in late autumn. 

 There are said to be^ forms that vary considerably in 

 hardiness. The plant is hardy in most parts of England 



4035. Ear or pistillate spike of maize. The husks are a kind 

 of involucre. Each kernel represents a flower. The "silks" are 

 styles.
