32. Cyathea macrosora (Baker) Domin (1929: 263) View in CoL . Alsophila macrosora Baker in Im Thurn (1886: 211). Hemitelia macrosora (Baker) Jenman (1898: 45) . Sphaeropteris macrosora (Baker) Windisch (1973: 372) . Type:— GUYANA. Mount Roraima, 5750 ft, Im Thurn 87 (holotype K, isotype US).

Distribution and habitat: — Colombia, Venezuela, Guyana, Suriname, French Guiana at 100–1700 m.

Remarks: — Windisch (1978) recognized two varieties in Cyathea macrosora : var. reginae and var. vaupensis , which are currently treated as separate species, C. traillii and C. vaupensis . Cyathea macrosora is characterized by variably bicolored scales and the general absence of scurf. The indusia of the studied material are not as variable in size as pointed out by Windisch (1978), who reports that the indusia may be almost lacking.
