Cyrtandra alaustri H. St. John , Phytologia 63: 487. 1987.
Type information:
Holotype [BISH]. B.C. Stone 1489. 26 December 1956. Kaua`i: Wainiha, [near dam].800ft.

Note: The citation of the collection number 1489 appears to be an error because a specimen of Stone 1498 agrees in locality and description and is thus considered the probable holotype. St. John apparently intended his epithet to be spelled "claustri".

Note: The citation of the collection number 1489 appears to be an error because a specimen of Stone 1498 agrees in locality and description and is thus considered the probable holotype. St. John apparently intended his epithet to be spelled "claustri".
