Which genus contains the most species, Chrysanthemoides or Phlox?
Chrysanthemoides Chrysanthemoides is one of eight genera of the Calenduleae, with a centre of diversity in South Africa. The genera contains only two species, but is known for the invasive "Bitou Bush" "Chrysanthemoides monilifera". Studies of this genus have determined that there is a large amount of genetic variation between populations, suggesting an extreme adaptive capability in the plants. Some of these variations are recognised, such as "Chrysanthemoides monilifera" subsp. "rotundata".
Phlox subulata Phlox subulata (creeping phlox, moss phlox, moss pink, or mountain phlox) is a species of flowering plant in the family Polemoniaceae, native to eastern and central USA, and widely cultivated. Growing to 15 cm high and covering a 50 cm wide area, it is an evergreen perennial forming mats or cushions of hairy, linear leaves. The small, five-petaled flowers bloom in rose, mauve, blue, white, or pink in late spring to early summer.
