Orchids Found in SI



Today I went out with my pal Ray to root around along Staten Island's south shore...won't say exactly where...and we found two orchid species new to City records – large coralroot (Corallorhiza maculata) and bog twayblade (Liparis loeselii). Large coralroot lacks greenery - it has tawny brown stems and no leaves. This is because it does not photosynthesize. It is saprophytic, meaning it feeds off organic matter, like fungi. It is added in its nutrient intake by a short, stubby, branched root that resembles coral.
Small white, purple spotted flowers appear in late summer.

As the name suggests, bog twayblade is found in wetland, open habitats. It has unremarkable yellowish-green flowers that are only 1/4” long that bloom in late summer.
