develops into a flowering stem ; after flowering this dies, but at 

 its base two opposite buds have been formed, only one of which 

 develops the following season, and this manner of growth is con- 

 tinued from season to season. 



12. In Viburnum nudum the bud scales are composed of the 

 bases of leaves,their morphological nature becoming evident by the 

 development of leafy tips or blades in spring. 

 (Fig. 6, outer scale ; fig. 7, inner scale.) 

 These leafy tips are formed on the scales of 

 both leaf and mixed buds, but owing to the 

 falling off of the more evident broader scales 

 early in the spring while their blades are still 

 quite small, and their consequent non-pres- 

 ervation in herbaria, the fact is generally 

 overlooked. The development of the base 

 here before the tip of the leaf forms an excep- 

 tion to the usual rule that the development of 

 leaves proceeds from their tips to the base. — Aug. F. Foerste,

Teratological Notes. 



1. A Botryehium with three fertile segments — Among the nu- 

 merous specimens of B. Lunaria,, Swartz, sent by Mr. S. M. 

 Turner from Afbgnak Island, Alaska, there is one that has two 

 secondary fertile segments standing on the main fertile segment 

 of the frond. They start from it near its commencement, and 

 are all nearly the same size. All appear fully developed, bearing 

 about the usual number of sporangia. 



2. Ludwigia alternifolia with a broad stem. — During the past 

 August I found a specimen of this species in which the upper 

 half of the stem was only about one eighth of an inch thick, 

 while in breadth it measured from one-half to an inch. It sent 

 out, at the sides, short flower bearing branches. The plant grew 

 in a swamp, was nearly four feet high, and otherwise thrifty. 



3. Ranunculus repens with flat peduncles. — During the past 

 summer I found several examples of this species in which the 

 peduncle was flat, and bearing on its top an irregular mass of 

 petals. 



A. Two Oaks grown together. — Within three miles of Mt. 

 Carmel (111.) there is an Oak (Q. palustris, Du Roi), which 

 commences with two roots ; these are so close together and inter- 

 grown as to appear as one at the surface of the ground. The
