Corallorhiza maculata, or spotted coralroot, is a North American coralroot orchid. It has three varieties: C. maculata var. occidentalis (western spotted coralroot), C. maculata var. maculata (eastern spotted coralroot or summer coralroot), and C. maculata var. mexicana. It is widespread through Mexico, Guatemala, Canada, Saint Pierre and Miquelon, and much of the western and northern United States (though generally absent from the Great Plains and from the lowland parts of the Southeast). It grows mostly in montane woodlands.
Description
Corallorhiza maculata is a myco-heterotroph; it lacks chlorophyll and obtains energy by parasitizing the mycelium of fungi in the family Russulaceae. The rhizome and lower stem are often knotted into branched coral shapes. The stem is usually red or brown in color, but occasionally comes in a light yellow or cream color. There are no leaves and no photosynthetic green tissues. The stems bear dark red scales and intricate orchid flowers.
Corallorhiza maculata flowers are small and emerge regularly from all sides of the stem. The sepals are dark red or brown tinged with purple, long and pointed. The side petals are reddish, and the lip petal is bright clean white with deep red spots. It is usually scalloped along its edges and . In some varieties, the lip may be plain white without spots.
Taxonomy Corallorhiza maculata was scientifically described and named by Constantine Rafinesque in 1817. It is classified in the genus Corallorhiza within the family Orchidaceae. It has three varieties according to Plants of the World Online:
Corallorhiza maculata var. maculata Corallorhiza maculata var. mexicana Corallorhiza maculata var. occidentalis
Corallorhiza maculata has synonyms of the species or one of its three varieties.
