FIGURE 1 in Seed morphology of Boschniakia sensu lato (Orobanchaceae) and its taxonomical implications

FIGURE 1. Micromorphology of seeds of the studied species in SEM micrographs (surfaces). A–E: Boschniakia rossica. F–J: B. himalaica. K–O: Kopsiopsis hookeri. P–T: K. strobilacea. A,B,F,G,K,L,P,Q: general habit of seeds selected to show the variability of external shape (K,L,P,Q—seeds with most of the diaphragms still present). C–E, H–J, M–O, R–T: enlargements of cells and reticulate sculpture (C,H,M,R—seeds with interrupted diaphragms); black arrows indicate the diaphragms; white arrows beginning with an 'x' indicate the shaft between cells in B. rossica (D); normal white arrows show the narrow trough continuous in B. himalaica (I), K. hookeri (N) and K. strobilacea (S). Scale bars 1 μm (E), 10 μm (B–D,I,J,O,S,T), 100 μm (A,F–H,K–N,P–R).
