I have long thought that in addition to trifasciata, the other naturalized sansevieria in FL was the one known locally as S guineensis that I thought was a cultivar of S metallica., I just came across an article (see link) where the author, states the species is actually S.hyacinthoides. Here's the text. The photo is my plant
Sansevieria hyacinthoides (L.) Druce, Bot. Exch. Club Soc. Brit. Isles 3: 423. 1914. Aloe hyacinthoides L., Sp. Pl. 1: 321. 1753. Cordyline hyacinthoides (L.) W. Wight, Contr. U.S. Natl. Herb. 9: 249. 1904. LECTOTYPE (designated by Stearn 1961): GUINEA. C. Commelin, Praeludia Bot. 84, t. 33. 1703.
Though Sansevieria hyacinthoides appears to spread vegetatively only, it is widespread in central and south peninsular Florida. It can form dense colonies from its thick, bright orange rhizomes. This species was depicted by Dodge in 1893 (as S. guineensis (L.) Willd.) as a potential fiber crop and may have been introduced to Florida much earlier than 1893 (Henley 1982). The earliest specimen I have seen from Florida was collected by Britton in 1903 from Ã¢ÂÂwaste placesÃ¢ÂÂ in Key West (NY). I have not seen any herbarium specimens with fruits in Florida.
