Bulbous plants with a terminal racemose inflorescence; the anthers open introrsely and the capsule is loculicidal.
Pretty liliaceous plants, with simple conspicuously longitudinal-ribbed leaves, the racemose flowers funnel-shaped and deflexed.
Every variety of racemose and paniculate inflorescence obtains, and the number of spikelets composing those of the large kinds is often immense.
Thus we may have a group of racemes, arranged in a racemose manner on a common axis, forming a raceme of racemes or compound raceme, as in Astilbe.
Again, there may be a raceme of capitula, that is, a group of capitula disposed in a racemose manner, as in Petasites, a raceme of umbels, as in ivy, and so on, all the forms of inflorescence being indefinite in disposition.
In such cases the cymes are described as spiked, racemose, or panicled, according to circumstances.
In the bell-flower (Campanula) there is a racemose uniparous cyme.
In the privet (Ligustrum vulgare) there are numerous racemes of dichasia arranged in a racemose manner along an axis; the whole inflorescence thus has an appearance not unlike a bunch of grapes, and has been called a thyrsus.
