Early Cretaceous angiosperm leaves from the Dakota Formation, Hoisington III locality, Kansas, USA Author Wang, Hongshan Author Dilcher, David L. text Palaeontologia Electronica 2018 34 A 2018-09-30 21 3 1 49 http://dx.doi.org/10.26879/841 journal article 10.26879/841 1094-8074 11062827 Crassidenticulum decurrens (Lesquereux) Upchurch and Dilcher, 1990 Figure 4.1 *1892 Celastrophyllum decurrens Lesquereux , p. 172, plate 36, figure 1. Description. Leaflet margin toothed. Primary venation pinnate; primary vein massive, course straight. Secondary venation mixed craspedodromous (most of the secondary veins terminating at the margin and the rest brochidodromous); secondary veins thin, angle of divergence wide acute at 80 ° ; course of secondary veins irregular, straight, slightly curved or recurved; secondary veins densely arranged, 5 to 10 pairs per cm at middle portion of lamina, spacing irregular; intersecondary veins common. Veins of higher order not observed. Number of specimens examined. 2. Specimens illustrated. UF 15706-24648 ( Figure 4.1 ). Occurrences. Rose Creek locality, Nebraska ; Braun Ranch and Hoisington III localities, Kansas . Remarks. The venation pattern and tooth type of the two leaflet fragments are consistent with those described by Upchurch and Dilcher (1990) and Wang and Dilcher (2006a). Therefore, we interpret this specimen as conspecific and the blade as a leaflet. The chloranthoid tooth type (tooth with a prominent, often thickened gland, a medial vein and a pair of accessory veins that run along the tooth margin and fuse with the gland) and the secondary venation pattern of Crassidenticulum show its closest similarities with extant Chloranthaceae (Upchurch and Dilcher 1990) .
