PELORIA IN HABENARIA 



Anne E. Perkins 



I collected in Vermont an abnormal orchid. The specimen was 

 sent to C. A. Weatherby who writes concerning it as follows: 



"I have just received the queer orchid which you collected at 

 Berkshire, Vt., back from Professor Ames. He states that my second 

 conjecture was correct and that the plant is an abnormal form of 

 Habenaria psycocles. It is an example of the phenomenon known as 

 peloria by which (this in case you do not happen to be familiar with 

 the term) an irregular flower becomes regular by the duplication of 

 one or another of its parts to the exclusion of those which differ from 

 it. In this case the petals are repeated and the lip with its spur is 

 eliminated. 



"Following the clue given by Professor Ames, I find some litera- 

 ture on the subject which I had previously overlooked. A precisely 

 similar form has been recorded in Habenaria fimbriata (Lynn, N. H., 

 H. G. Jesup, Dot. Gaz. xviii, 189) and also in H, ciliaris. The opposite 

 kind of peloria in which the petals have spurs like the lip has also 

 been at least once noted in a species of Habenaria. 



"In the case of your flower the peloria seems also to have extended 

 to the stamens which, by the production of one or two additional 

 anther-sacs, show a partial reversion to a primitive regular-flowered 

 type. I flnd a similar phenomenon recorded in a peloric flower of a 

 European species. 



"Professor Ames does not say whether he has seen such a form in 

 Habenaria psycocles before; but I find no record of one." 



WOODSTOCK PLANTS 



E. M. Kittredge 



Among the plants I have collected for Miss Billings in the town 

 of Woodstock are more than 50 recorded from only a few stations in 

 the state and 35 others not mentioned in the 1915 issue of the Vermont 

 Flora. Of these not recorded, perhaps a few of the most interesting are 

 Ribes rotundifolium, Euphorbia glyptosperma, Vitis aestivalis, Oeno- 

 thera muricata var. canescens, Pentstemon pallidus, Houstonia coeru- 

 lea, var. Faxonorum, Lonicera Xylosteum, Achillea ligustica, Artemisia 

 annua, Chrysanthemum Parthenium, Hieracium pilosella var. viride,
