Monographs Details: Chimantaea
Authority: Carlquist, Sherwin. 1957. Anatomy of Guayana Mutisieae. Mem. New York Bot. Gard. 9 (3): 441-476.
Scientific Name:Chimantaea
Discussion:Although not conspicuously different from those of the above genera, the pollen grains of Chimantaea have somewhat more prominent spines and greater exine thickness. While some species are spinulose, such as C. rupicola (fig. 93 A, B), others are more nearly psilate, such as C. similis (Fig. 93 C). The variation in shape of pollen grains is approximately that found in Stenopadus, ranging from subprolate to prolate sphaeroidal. In size, the pollen grains of Chimantaea also fall within the range found in Stenopadus.
