Solution and Explanation
Step 1: Understanding the Concept:
The genus Ixora (family Rubiaceae) consists of evergreen tropical shrubs popular in landscape gardening for their dense, showy corymbi-form flower clusters.
While most common ixoras have red, orange, or yellow flowers, certain species are valued specifically for their white, fragrant blossoms.
Step 2: Detailed Explanation:
Let us examine the flower colors of each listed Ixora species:
A. Ixora acuminata (Sharptooth Ixora): This is a large, highly ornamental tropical shrub.
It is famous for producing large, dense clusters of highly fragrant, star-shaped white flowers. Thus, A is correct.
B. Ixora armeniaca: As suggested by the species name 'armeniaca' (meaning apricot-colored), this species produces apricot-orange or salmon-colored flowers. Thus, B is incorrect.
C. Ixora superba: This is a spectacular robust species known for its exceptionally large, highly fragrant white flower clusters. Thus, C is correct.
D. Ixora chinensis: Commonly known as Chinese Ixora, this is the classic garden species that produces dense clusters of bright orange, red, or golden-yellow flowers. Thus, D is incorrect.
Therefore, only Ixora acuminata (A) and Ixora superba (C) bear white flowers.
