Narcissus (plant) corona. Floral tubes can range from long and narrow in sections "Apodanthi" and "Jonquilla" to rudimentary ("N. cavanillesii"). Surrounding the floral tube and corona and reflexed (bent back) from the rest of the perianth are the six spreading tepals or floral leaves, in two whorls which may be distally ascending, reflexed (folded back), or lanceolate. Like many monocotyledons, the perianth is homochlamydeous, that is undifferentiated into separate calyx (sepals) and corolla (petals), but rather has six tepals. The three outer tepal segments may be considered sepals, and the three inner segments petals. The transition point between the floral tube and
Trifolium variegatum cluster over 2 centimeters wide. At its base is a fused involucre of bracts. Each flower has a calyx of sepals narrowing to bristle-like tips. The flower corolla is generally purplish in color and usually has a white tip. Trifolium variegatum Trifolium variegatum is a species of clover known by the common name whitetip clover.
