about Cotuit. I saw no other species of Lechta abundant there; 

 though L' major. Mchx., and Z. thymifolia, Pursh, (Z. Novae-Caesa- 

 reae, Austin), are found in the vicinity. Z. ma^Htijna was constantly 

 under my eyes, but I never saw the flowers opened^ till on a bleak, 

 sunless day, during a northeasterly gale, about the i8th of August, 

 I noticed that the Lecheas in a hollow through which I was passing 

 were all in bloom. So different was the aspect of the plant, that it at 

 once arrested attention. The next day, and the next, I found other 

 patches in bloom, patches with which I was familiar, as they were 

 near the house. Rosa, a child of ten, who knew pin-weed quite well, 

 brought me a piece of the full-blown plant to learn its name. She 

 did not recognize it in its new dress. The small petals were of a 

 brownish-red, but the conspicuous stigmas were white with a yellowish 

 tinge. This is the only time I have seen Lechea in full bloom.

J 13. A large Grape-vine.— In a wooded ravine near Egbert- 

 vine, Staten Island, there is a vine of Vitis cordifolia, Michx., having 

 a circumference of twenty-five and one-half inches at a point three 

 feet above its base. It completely covers three cedar trees, each at 

 least thirty feet high, and is a very beautiful plant.

 114. Cheilanthes rayriophylla, Desv.— I desire specimens of 



this fern, -with root-stocks, from Mexico or South America for a 

 special study of the Myriophylla-Fendleri group of Cheilanthes. 



I will be glad to communicate with any one who can put me in 

 the way of obtaining them, and to return specimens of other species 

 in exchange. Address, 



Medford, Mass., U. S. A. Geo. E. Davenport. 



115. Woodsia Obtusa, Torrey.— I would like to obtain some 

 full suites of specimens of this species in different stages of develop- 

 ment, from the Middle, Southern, or South-western States, and will 

 be glad to make such exchanges for them as I can.

_ 116. Botanical Notes.— ^ Locomotive Dicotyledon.— Kxi inter- 

 esting case of voluntary motion among dicotyledonous plants, in a 

 species of Loranthus, has been discovered by Dr. G Watt of the Fd- 

 ucational Department, Bengal Lower Provinces, and made known^in 

 a recent number of the Gardeners Chronicle. It is only while the 

 seed IS germmatmg that the motion takes place, but the mode of 

 travelling is very peculiar and quite different from that of any other 

 known plant. I he plant is a native of Bengal, and like all other 

 members of the genus is parasitical, growing upon a few evergreen 

 trees, particularly upon some species of Memecylon. The fruit like 

 that of Its relative, the mistletoe, and nearly all other members of the 

 order, consists of a mass of very viscid pulp surrounding a sin-le 

 seed, and on separating from the parent plant adheres to whateve^it 

 may chance to fall upon, and after a time begins to germinate It is
