Dipsacus fullonum Europe-Asia B (L.
Knautia macedonica, with its tall slender flower stems and deep purple-red flowers will start to flower over the next few weeks and will, like most Dipsacaceae
plants, support a good bee population.
Taxonomic subdivision of these families follows Polhill and Raven (1981) for the Leguminosae, Riedl (1967) for the Boraginaceae, Erdtman in Cantino (1992) for the Labiatae, Melchior (1964) for the Scrophulariaceae, and Caputo and Cozzolino (1994) for the Dipsacaceae.
interrupta visits either sub-family of the Dipsacaceae.
One of them is specialized on Cardueae (Compositae), the other collects pollen exclusively on Dipsacaceae demonstrating a clear transition of oligoleges between different plant taxa.

Such graded morphs occur in some Brassicaceae (Iberis) (Busch & Zachgo, 2007), Apiaceae (Orlaya) (Froebe, 1980; Classen-Bockhoff, 1992), Asteraceae (Hieracium), and Dipsacaceae (Scabiosa) (Kunze, 1976) (Fig.
Furthermore, in some Adoxaceae (Sinadoxa) and in Dipsacaceae the gynoecium is unilocular and uniovulate (Donoghue et al.

Knautia arvensis (L.
A series of articles by Philipson (1946, 1947a, 1947b, 1947c, 1948) compared histogenetic changes of the apical meristem, based on histological sections, during inflorescence onset and flower initiation in several taxa of Asteraceae, plus taxa of adjacent families Valerianaceae and Dipsacaceae
Unequivocal examples of tertiary syncephalia are rare in the Asteraceae (found only in four genera to date) but are often found in other families such as the Dipsacaceae and Calycer aceae.
Rauh and Reznik (1953) documented the various degrees of meristematic activity of the histogenetic zones in the developing inflorescences of representative species of Asteraceae, as well as some species of Dipsacaceae and Campanulaceae.
