Pelargonidin is the predominant pigment causing the red coloration in the spathes. The capsule is carried high above the dried remains of the long spathes. The deep lilac to purplish spathes are long. Developing flowers are covered in mucilaginous spathes. The stem also has keeled, lanceolate, green, spathes (leaves of the flower bud) (or bracts). It is the predominant pigment causing the red coloration in the spathes of "Philodendron" (Araceae). These have larger spathes than either of the parents. The lower spathes are green and leaf-like. During this season the stout male spathes split and their inflorescences reach maturity. It has green spathes (leaves of the flower bud), which are slightly keeled, and long. The flower is protected by two spathes, both of which are round in cross-section. The stem has (scarious) membranous, (or translucent) spathes (leaves of the flower bud). These spathes are often filled with a mucilaginous liquid. The flowers are deep red, fragrant spathes up to long, in summer and autumn. The spathes are around long and slightly divided only at the tip.
