THE ORCHIDS OF NEW ENGLAND. 73 
species of the tribe. We have observed that this species is 
very ‘fertile, usually maturing all its ovaries.” 
The genus Corallorhiza (Coral-root), northern or extra-tropi- 
cal in range and containing about ten species, has four repre- 
sentatives in the North-eastern United States, three of them oc- 
curring in New England. This genus follows Liparis in Gray’s 
Botany; the plants are supposed to be root-parasitical,* and 
send up “a simple scape, furnished with 
sheaths instead of leaves, from a much 
branched and toothed coral-like root-stock.” 
The lip, “slightly adherent to the base of the 
2-edged straightish column,” “is often more 
or less extended into a protuberance or 
“short spur coalescent with the ovary.” The 
anther is “terminal, lid-like.’ The 4 pollen- 
masses are “soft-waxy or powdery, and have yg. 92 Roor or 
no stalks or connecting tissue.” C. zunata LPR RBEA: 
(Early Coral-root), and C. odontorhiza (Dragon-claw, Coral-tooth, 
Small Late Coral-root) are mentioned together here, although 
the latter belongs rather to July, in Vermont, because the next 
Orchid mentioned is a near relative and might be mistaken for 
them. C. zznata, which Hooker says closely accords with the 
European species, is a low dingy-green herb bearing a few spur- 
less flowers, and found in swampy or wet shaded places. Grow- 
ing as far south as Georgia, it yet follows Calypso across the 
6oth parallel, but notwithstanding this extensive range, it is 
rare. C. odontorhiza is found in Florida, and Chapman makes 
the singular statement that although vernal in the North it does 
not bloom till September and October in the South. This 
Coral-root has a depression where its flower-spur should be. 
From its greater height, which may be sixteen inches, and its 
* Sachs (Botanical Text Book) calls the Coral-roots, particularly C. zxnata, 
““saprophytes,” because they ‘‘make use . . . of the material of other plants 
' which are already in a state of decomposition.” |
