6 Wilson — Obscnuxtions on 



Franklin County, May 23, in flower. 



Allegheny County, June 19, in full flower. 



Mercer County, June 12, in full flower. 



It was reported from Staten Island, N. Y., as in fruit July 

 II, 1895 ; and coming southward into southwestern Virginia, it 

 was there already past bloom as early as June 8, 1892 ; in 

 flower, but passing out, in Blowing Rock, N. C. (exception- 

 ally high), June 16-17, 1892; while in Florida, it was in 

 flower as early as March and April. 



Apparently, then, the period of flowering lasts about two 

 months, beginning in early May in our Middle States, but, as 

 might be expected, even two months earlier farther south. 



IV. Relationship to Other Members of the Order. 



The flowering stalks, always some distance from the trunk 

 of the host, are remarkable in appearance. Unlike the other 

 members of this order, they are thick and fleshy. Their color 

 is a chestnut brown. They are six inches in length when 

 fully grown, covered with thick, membranous-fleshy scales, in 

 the axils of the upper ones of which are found the flowers. 

 These are of the same color as the leaves, and like all of the 

 Oroba7ichca, have a marked resemblance to non-parasitic 

 Scroplndariaccct. There are two bracts at the base of the 

 calyx, which is irregularly four to five-toothed and split pos- 

 teriorly to the base. The upper lip of the two-parted corolla 

 is entire, or notched ; the lower three-parted with the middle 

 division obtuse and larger than the other three. The stamens 

 are protruded, and the one-celled ovary is full of ovules 

 attached to four parietal placentae. These differ but slightly 

 from the flowers of the other closely related American genera, 

 Phclipaa and Apliyllon. The most noticeable point of differ- 

 ence is the protruded stamens. 



The calyx of PhcHpaa is not cleft down the middle, and 

 there is a well-developed ovarian gland, of which there is also 

 a microscopic indication in the very young flowers of Conopho-
