The characters which distinguish it are very well displayed in the two types we have selected for examination. The great feature is the aggregation of the flowers on a spadix. Generally, though not invariably, a spathe is also present. Among wild plants the Skunk Cabbage and Sweet Flag (the latter without a spathe) are common Araceous types, while the familiar green-house and window plant, known as the Calla-Lily, will serve very well for examination in winter. It may be added that the plants of this Order have a very acrid juice. Fig. 100.—Perfect flower of Calla. I t' <3 1:1 I :':i i : " , *.
