intimum 4-5 lin, longum, 6-7 lin. latum, tenuiter hyalino-membranaceum, reticulatim rubrovenium, margine 
obscure sinuato-trilobum, ceeterum obtusissimum et integerrimum, facie undulato-concavum fructum includens,

A much stronger and stiffer plant than the very delicate P. drymarioides, 
and remarkable for the large involucres which surround the seed, coloured and 
veined something like those of a Bougainvillea. Each leaf of the involucre, both 
in this and the P. drymarioides, is evidently formed of the union of three, the 
contiguous margins of which expand into the dorsal wings or crests from whence 
the generic name is divided, thus assimilating the whole involucre to the usual 
hexamerous arrangement in other Eriogonee.
