Question

In Anthocephalus the inflorescence is _____________.
A. Raceme
B. Cymose head
C. Racemose head
D. Corymb

Answer 1

Hint:-An inflorescence is a group or cluster of flowers clustered on a stem that consists of a main branch or a complex branch arrangement. Morphologically, where flowers are produced, it is the modified part of the seed plant shoot.

Complete solution:An unbranched, indeterminate type of inflorescence containing pedicellate flowers along its axis is a raceme or racemoid. An axis means a shoot in botany, one bearing flowers in this instance.

Cymose Capitulum or Head-The peduncle or the main stem is in the form of a circular disc in this type. The formation is identical to the head of a race. The flowers are either sessile or sub-sessile, and are arranged like a globose head in a centrifugal order. Glomerulus are sometimes referred to as the globose ears. Anthocephalus cadamba, Albizia for example.

Racemose is a type of inflorescence that continues to develop indefinitely on the main axis and does not end in flowering. This is why it is often referred to as an inflorescence that is indefinite or indeterminate. Examples: Helianthus annuus (Sunflower), Zinnia, Tagetes erecta (Marigold), Cosmos, Acacia, Mimosa pudica, etc.

For an inflorescence with the flowers rising in such a way that the outermost are borne on longer pedicels than the inner, Corymb is a botanical word, taking all flowers to a similar level.

So from these discussions we can conclude that the inflorescence in Anthocephalus is Cymose head. Therefore the correct answer is option (B).

Note:-
Anthocephalus was, but is no longer known, a genus of flowering plants in the Rubiaceae family. Neolamarckia or Breonia have been plunged into synonymy. Any flower in an inflorescence, especially when the individual flowers are particularly small and borne in a close cluster, such as a pseudanthium, can be referred to as a floret. The fruiting process of an inflorescence is referred to as an inflorescence. Inflorescences may be plain (single) or panicle-complex.
