Argyreia and Dipcadi, have which mutual characteristic?
Dipcadi Dipcadi is a genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae (also treated as the family Hyacinthaceae). It is widely distributed, occurring in southern Europe, most of Africa and the Middle East through to the Indian subcontinent.
Diplazium pycnocarpon Diplazium pycnocarpon (narrow-leaved glade fern, narrow-leaved-spleenwort, glade fern) is a tall slender-leaved fern growing as individuals with 5 to 6 leaves. The plant spreads by creeping underground stems allowing a small colony to develop over time. The leaf blade is oblong-lanceolate and once-pinnate, unlike the closely related "Athyrium". Leaves grow to about 90 cm (36 in) long and 15 cm (6 in) wide. The pinnae are linear and entire. Fertile leaves are similar but erect, narrower than sterile leaves and with longer stipes. The sori are long and narrow in two lines along the underside of a leaf pinna, giving rise to its specific epithet "pycnocarpon" ('crowded fruits').
