Question

In family Liliaceae flowers are

• A. Trimerous and hypogynous
• B. Pentamerous and epigynous
• C. Trimerous and epigynous
• D. Pentamerous and hypogynous

Answer 1

The correct option is A Trimerous and hypogynous

Liliaceae flowers - Hermaphroditic, actinomorphic (radially symmetric) or slightly zygomorphic (bilaterally symmetric), pedicellate (on a short secondary stem), generally large and showy but may be inconspicuous (Medeoleae). Bracts may (bracteate) or may not (ebracteate) be present. The perianth is undifferentiated (perigonium) and biseriate (two whorled), formed from six tepals arranged into two separate whorls of three parts (trimerous) each, although Scoliopus has only three petals, free from the other parts, but overlapping.
Liliaceae gynoecium - Superior ovary (hypogynous), syncarpous (with fused carpels), with three connate (fused) carpels and is trilocular (three locules, or chambers) or unilocular (single locule, as in Scoliopus and Medeola). There is a single style and a three lobed stigma or three stigmata more or less elongated along the style. There are numerous anatropous (curved) ovules which display axile placentation (parietal in Scoliopus and Medeola), usually with an integument and thinner megasporangium.
Therefore, the correct answer is option A.
