PLANT DESCRIPTION 225 
which, though markedly distinguishing them from 
examples already described, are not gufficient to 
warrant their being placed in separate orders. 
Peony—tuberous roots and large flowers; sepals 
five, passing gradually outwards into the foliage leaves; 
five or more petals without nectaries ; numerous stamens 
and two or three large fleshy earpels, joined at their 
bases and producing nectar from a dise by which they 
are surrounded. 
2. Columbine (Aquilegia) five petaloid sepals; five 
petals with long nectar spurs; numerous stamens in 
regular rings; inner stamens without anthers; carpels 
five or more; fruit an etario of follicles. 
3. Nigella (Love-in-a-mist, Devil-in-the-bush). Flower 
has involucre of five leaves; five petaloid sepals; 
five to eight pocket-like nectaries each with a lid; 
five carpels with united ovaries which split when 
ripe along the partitions. 
4. Larkspur (Delphinium). Five petaloid sepals, 
the uppermost spurred; only two upper petals 
developed as a rule; the two spurs of these project 
into the sepal spur and are pressed together go as to 
form a tube above and a solid nectary below; carpels 
three to five often reduced to one; fruit an etario of 
follicles or a single follicle. 
5. Anemone. Sepals petaloid, petals wanting. In 
double flowers many of the stamens become petaloid. 
Receptacle much elongated. 
CRUCIFERAE. 
The Wallfiower (Fig. 126-127) (Cheiranthus cheiri) 
is a typical crucifer. 
Habit. A perennial plant largely cultivated for 
its flowers. 
Root. Much branched woody tap-root (as in the 
case of most dicotyledons).
