Concentric Annual Growths. — There is no connection between 



the longitudinal (branch) growth of plants, and the generation of 

 the cells which form the annual layers of wood in the trunk. Quercus 

 Robur often has two distinct periods of longitudinal growth the same 

 season in Europe, and in our country nearly always three — but I 

 have never seen more than twelve annual circles of wood in a twelve- 

 year old tree, though I have seen and counted many when cut down 

 for poles at that age.

Teratological Notes. (From observations made during the season 

 of 1881). — Symplocarpus foeiidus^ Salisb., with two spathes, one within 

 the other, the opening of the inner facing the back of tlie outer ; no 

 spadix. Also a specimen of the same plant with a tuft of well-de- 

 veloped leaves from the centre of the spathe, in place of the usual 

 spadix. 



Podophyllum peltatum^ L., with a single peltate leaf, having a 



flower-bud about one inch below it, and with one of the bud-scales at 



the surface of the ground bearing at its summit a small sub-peltate 



leaf. Also a specimen of the same plant with three peltate leaves; 



two of these forking above the insertion of the first, and bearing the 

 flower in the axil. 



Hepatica triloba^ Chaix., with four involucral leaves, the outer of 

 which was enlarged, and evidently three-lobed. 



Claytoiiia Virgi7iica, L., with unequally bifid, or slightly laciniate " 

 petals. 



Houstonia caerulea, L., one flower having six sepals and six petals, 

 and two or more flowers with five sepals and petals, growing close 

 together, but not from the. same root. The six-parted one had also 

 a four-parted flower on a branch of the same stem. Also, in an- 

 other locality, a plant with a three-parted flower. 



Ranunculus bulbosus^ L., with the principal stem flattened, about . 

 one-half inch wide, and terminating in a distorted head of fruit.* 



Also a scape of Taraxacum deformed in a very similar manner to 

 the above. 



• Plantago lanceolata, L., bearing two diverging spikes from the 

 summit of the same scape. 



Vesbascuvi ; evidently a hybrid, and probably V, Blattaria, L., 

 fertilized by V. Lychnitis, L. It had the general appearance of the 

 former, but tended to branch more paniculately, and to have more 

 flowers (about 4) from the axil of the same bract. The stem was 

 slender, with the leaves more tapering and more woolly than in the 

 last, and the flowers were also slightly less. The pods did not seem 

 to develop fully, and, as far as observed, no seed oerfected 



• Fasciation in this species, as well as in repens and a:ris, was more than ordi 

 narily common m the vicmity of New York last spring.— Eds.
