The campanulate (Lat. campanula, bell) denotes a bell-shaped calyx or corolla (Fig. 60). The tubular form spreads above but little. The two upper petals maj' unite closely and form a kind of upper lip, and the three lower ones unite to form a lower lip. In such case the corolla is labiate (Lat. labium, lip). The calyx may also be labiate, or two-lipped. 9. Examine a flower-head of a Sunflower; it will be seen to consist of numerous florets, with tubular corollas interspersed with the bristles or chafi'. There will also be found a row of marginal flowers, called ray flowers. These have strap-shaped corollas, which are said to be ligxdate (Lat. ligiila, tongue). In the Dandelion all of the florets are ligulate. A curious shape is presented by the Pea or Bean. The corolla is choripetalous, very irregular, with a vague resemblance to a butterfly, and for this reason it has received the name papilionaceous (Lat. papilio, butterfly) ; the upper and larger petal is called the banner, the two side petals are called the vmigs, and the two anterior ones, generally cohering slightly and enclosing the stamens and pistil, are called the keel. The flowers of the Cress, Mustard, Cabbage, etc. have four petals, arranged two and two opposite, somewhat like a Greek cross, and they are said to be cruciform (Lat. crux, cross)..
