Origin of the cyathium-bearing Euphorbieae (Euphorbiaceae): phylogenetic study based on morphological characters (2674 words)
The pollen grains of Crotonoideae are mostly inaperturate with triangular supratectal elements completely absent in Euphorbieae (Park and Lee, 1988; Nowicke, 1994; Webster, 1994b).
Ingroup monophyly of Euphorbioideae, as compared to sister groups Crotonoideae and Acalypoideae, is supported by a number of apomorphic characters such as whitish latex, simple trichomes, apetalous flowers, lack of a disk, absence of vascular bundles in the inner integument, and perforate-reticulate pollen exine (Webster, 1994b; Tokuoka and Tobe, 1995).
Croizat (1938) suggested that the structure of the inflorescence in the Euphorbieae is not fundamentally different from that of the Hippomaneae, except for the position of the axes, because the cyathium of Euphorbieae has resulted from the condensation of the male axis of Hippomaneae.
PBIO 450 Lecture Notes - Rosidae -- Spring 1998 (799 words)
The remaining subfamilies are Oldfieldioideae (4 tribes), Acalyphoideae Kostel (19 tribes), Crotonoideae Burmeist.
The flowers in both Acalyphoideae and Crotonoideae are unlike those of Euphorbia (see male and female flowers and fruits), but the genera here tend to be shrubby (or at least large if herbaceous) in the representatives that occur in temperate regions of the world.
Lactifers are generally absent in Acalyphoideae and generally present in Crotonoideae.
