| Oxybaphus
hirsutus or Mirabilis hirsuta (Hairy Four-o`clock) |
Family:
|
Nyctaginaceae (Four-O'Clock) |
| The stems, leaves
and calyx of Hairy Four-o'clock are pubescent. Stem leaves are sessile (attached
directly, lacking a petiole). Flowers (not shown) of Hairy Four-o'clock
are similar to flowers of Heartleaf
Four-o'clock, but plants are often seen after the petals have dropped
and the calyx remains (as in the photographed plants). Compare to Heartleaf Four-o'clock (Mirabilis nyctaginea) , which has hairless leaves which are attached with a petiole 1 cm or longer. Stems of Heartleaf Four-o'clock are also predominantly hairless. Some references suggest that M. hirsuta and M. nyctaginea might hybridize. Compare to Narrowleaf Four-o'clock (Mirabilis linearis), which has narrow, linear leaves. |
