Sansevieria hyacinthoides equals guineensis

Stush2049(Pitts., Pa. 6)August 25, 2013

What a confusing subject. I guess we need a DNA test to be sure but so many trifasciata cultavars has their equal in guineensis.
J.Chahinin describs 'Hyacinthoides' as a distinct species with some taxonomic controversy. Pg. 72 'The Splendid Sansevieria'.
Hyacinthoides Synonyms: Cordyline guineensis (L.) Britt., Cordyline guineensis (L.) Britton, Sansevieria guineensis (L.) Willd., Sansevieria metallica Horton ex Gerome & Labroy, Sansevieria thyrsiflora Thunb.
Sansevieria guineensis (Linnaeus) Willdenow, Sp. Pl. 2: 159. 1799
Sansevieria thyrsiflora Thunberg, Prodr. Pl. Cap. 65. 1794, nom. Illegit
Sansevieria metallica G�r�me & Labroy, Bull. Mus. Hist. Nat. (Paris) 9: 170, 173, f. 2. 1903.

So when we speak of hyacinthoides = guineensis = metallica, but definitely not trifasciata.

Just though of a way to check whether trifasciata or guineensis. Root a leaf cutting to see what develops from it. Should be able to tell it from there. Most cuttings loose the variegation and reverts back to original species.
Does anyone have anything to add to this?

In my imagination, I have thought that "guineensis" was brought to the New World from Africa maybe in the later 1700s or 1800s as a source of hemp and became naturalized. At one time I thought it might be a form of metallica, but a recent report by a S Fl Botanist said the wild sans growing in south FL was hyacinthoides, so I changed my mind. Such a plant being grown as a crop for a few hundred years could easily lose some of it's original traits. Like Stush says, we will probably have to await further genomic studies.
