Devonian Spores of Kryshtofovichia africani Nikitin (Tracheophyta): Morphology and Ultrastructure

open access: closedPaleontological Journal, 2018
The morphology and ultrastructure of spores of the Devonian plant Kryshtofovichia africani Nikitin are examined. The structure of ultrathin exine megaspores of K. africani is established. The exine consists of two layers: granular ectexine and lamellate endexine. Microspores have a lamellate ultrastructure with a trend toward loosening and formation of

Cyanogenic Compounds as Systematic Markers in Tracheophyta [PDF]

open access: closed, 1977
A short chronological review of cyanogenesis (Fig. 1) in vascular plants is given (Table 1). Subsequently the chemistry (Tables 2–4; Fig. 2) and biochemistry (Figs. 3–9) of cyanogenic plant constituents are summarized. Five biogenetical groups (A-E) of cyanogenetic compounds are presently known from vascular plants. The occurrence and function (Fig. 10)
