Discussion:Gustavia macarenensis subsp paucisperma differs from supsp macarenensis by having larger, oblanceolate leaves instead of smaller, elliptic ones.

Additional field work and collections from intervening areas are needed to determine if there are other differences between the two subspecies and to establish whether G. macarenensis is distinct from G. speciosa and G. parviflora.
