“…Catha ; Simmons, 2004a). Also in Lepidobotryaceae, the bases of the stamens, together with the disc, form a similar structure around the gynoecium (Badré, 1973; Link, 1991; Tobe & Hammel, 1993; this study).…”

“…In Lepidobotrys , a nectariferous disc extends between androecium and gynoecium and protrudes between the ten stamen bases; these bases plus nectary portions also form a short collar around the gynoecium (Link, 1991; this study). In Ruptiliocarpon This collar is longer and the nectariferous tissue seems to encompass the collar on both inner and outer sides (Tobe & Hammel, 1993).…”

“…The two pendulous ovules are bitegmic but they are not normally developed. A nectariferous disc extends between androecium and gynoecium and protrudes between the ten stamen bases (Figs 36I–M, 128), which form a short, shallow collar around the sterile gynoecium (see also Link, 1991). Sepal margins are decurrent for a short distance below the floral base.…”

Floral morphology, anatomy and histology in the newly circumscribed order Celastrales, comprising Celastraceae, Parnassiaceae and Lepidobotryaceae are studied comparatively. Several genera of Celastraceae and Lepidobotrys (Lepidobotryaceae) were studied for the first time in this respect. Celastraceae are well supported as a group by floral structure (including genera that were in separate families in earlier classifications); they have dorsally bulged-up locules (and thus apical septa) and contain oxalate druses in their floral tissues. The group of Celastraceae and Parnassiaceae is also well supported. They share completely syncarpous gynoecia with commissural stigmatic lobes (and strong concomitant development of the commissural vascular bundles but weak median carpel bundles), only weakly crassinucellar or incompletely tenuinucellar ovules with an endothelium, partly fringed sepals and petals, protandry in bisexual flowers combined with herkogamy by the movement of stamens and anther abscission, and stamens fused with the ovary. In contrast, Lepidobotryaceae are more distant from the other two families, sharing only a handful of features with Celastraceae (not Parnassiaceae), such as pseudohermaphroditic flowers, united stamen bases forming a collar around the gynoecium and seeds with a conspicuous aril. However, all three families together are also somewhat supported as a group and share petals that are not retarded in late floral bud development, 3-carpellate gynoecia, ventral slits of carpels closed by long interlocking epidermal cells and pollen tube transmitting tissue encompassing several cell layers, both integuments usually more than two cell layers thick, and only weak or lacking floral indumentum. In some molecular analyses Celastrales form an unsupported clade with Malpighiales and Oxalidales. This association is supported by floral structure, especially between Celastrales and Malpighiales. Among Celastrales, Lepidobotryaceae especially share special features with Malpighiales, including a diplostemonous androecium with ten fertile stamens, epitropous ovules with an obturator and strong vascularization around the chalaza.
