CORN A CEAE 
into corymb or umbel form, or even (Cornus) into heads with 
involucres. Firs, usually g , regular, 4 — 5 — 00 -merous. Typical 
formula K 4, C 4, A 4, G (2). There is an epigynous disc, and a 
simple style with lobed stigma. Ovary multi-loc., with usually 1 
pendulous ovule in each loc., the raphe of the ovule dorsal. Fruit a 
berry or more often a drupe, with a 1 — 4-loc. stone or 2 separate 
stones. Chief genera: Cornus, Garrya, Aucuba. 
Cornucopiae Linn. Gramineae (vm). 1 sp. Orient., C . cucullatum 
L. Firs, in small heads ; when the fruit is ripe these bend over and 
break off with a sharp point. They adhere to animals and are also 
said to burrow into the soil (cf. Stipa). 
Cornus (Tourn.) Linn. Cornaceae. 25 sp. Eur., As., Am. 2 in Brit., 
C. sanguinea L. the cornel or dogwood, and C. suecica L. The fir. 
of the former is biologically like that of an Umbellifer, but is homo- 
gamous. Its berry fruits are eaten by thrushes. The latter is a 
dwarf herbaceous perennial, common in the Highlands. Annual 
stems are given off from the creeping perennial stems. Firs, in 
umbels w T ith involucres of 4 large white bracts. C. fiorida L. (N. 
Am.) and others yield useful wood. C. mas (mascu/a) L., the 
Cornelian cherry (Eur., As. Minor), yields a fruit which makes good 
preserves. Its firs, appear in spring before the leaves (p. 103). 
Coronarieae (Benth. -Hooker). The 3rd series of Monocotyledons. 
Coronilla Tourn. ex Linn. Leguminosae (ill. 7). 20 sp. Eur., Medit., 
W. As. The fir. resembles that of Lotus, but the honey (at least in 
C. varia L. and others) is secreted by the outer surface of the calyx, 
and insects poke their tongues through between the claws of the 
petals, which are longer than usual. The buds are bent downwards, 
the open firs, project horizontally, the ripening fruits downwards and 
the ripe fruits usually upwards (p. 104).

One of the most remarkable firs, in existence. The fir. is pendu- 
lous ; the sepals are bent back and fairly large, the petals small. The 
labellum is of a most complex shape ; projecting horizontally from 
the base of the column is a bar bearing a dome on the end, from 
which is suspended a bucket-like organ; the mouth of the bucket 
faces upwards, and the edges are incurved ; there is also an overflow- 
pipe projecting towards the sepals and closely covered in by the bent 
end of the column, with the stigma and anther. From the base of 
the column project two horns which secrete a thin watery fluid that 
drips into the bucket, keeping it full to the level of the overflow pipe.
