To examine the seed morphology in Korean Orobanchaceae, seeds of 5 species including 1 variety in five genera and one related taxon, Boschniakia himalaica Hook. f. & Thomson in Hook. f. from the Himalaya (7 taxa in total) were investigated by scanning electron microscopy (SEM). Two different seed types are recognized depending on three characters (e.g, . the seed size, seed coat structure and seed number per fruit). -Type Ⅰ: size less than 1㎜, seed coat structure reticulate and seed number per fruit more than ca. 1,000; Type Ⅱ: size more than 1㎜, exotesta irregularly crested and seed number per fruit less than 1,000(Lathraea japonica Miq.). In Type Ⅰ, three subtypes of exotesta internal surface pattern can also be classified; (1) Subtype Ia: reticulate - include irregularly striate (Ia`) and deeply reticulate (Ia″), (2) Subtype Ib: foveolate, (3) Subtype Ic: smooth. Systematics application of the seed morphological data for the Korean Orobanchaceae is also briefly discussed. |
