As we are often aided in the study of the geographical wanderings 

 of phints, a list is appended of comparatively local plants, found in 

 companionship with Irientalis on the 8rd of June. 

 Allium Canadense Pogonia vertieillata 



Amelanchier Botryapium Polemonium rejitans 



Cypripedmm pubescens Pyrola elliptica 



Hypoxys erecta Pyrus arbuUfolia 



Medlola Vlrginiea Viburnum acerifolium 



Mitchella repens Viola px^bescens 



Goodyera pubescens Veratrum viride , 



Osmunda spectabilis Aspidium cristaium. 



Oxalis violacea 



On the glands in some Caryophyllaceous flowers. It cannot he 

 said that the existence of glands near the base of the common 

 chickweed and its allies, has been wholly overlooked, but they are 

 seldom referred to, and no attempt has been made to read their 

 significance. 



In regard to the chick-weed, Stellaria media. Withering notes in 

 the British Fhra (p. 547) "stamens glandular at the base." Dr. 

 Bromfield notes of a closely related species, Stellaria ulignosa, 

 " stamens 10, those alternating with the petals inserted on shortish, 

 flattened glands ; near, but not close to the base of the germen ; 

 being, in fact, above the latter and at the top of the conical enlarge- 

 ment of the calyx below the sepals" (Flora Vectensis 71). At p. 

 75, the same author notes oi Arenaria serpxjllijolia " stamens 5 to 10, 

 those alternating with the sepals placed on a projecting glandular 

 base, five shorter, having apparently abortive anthers." Of Sonek- 

 enya peloides, both Torrey and Gray and Withering note the ten 

 glands alternating with the stamens ; and Hooker remarks of Cher- 

 leria sedoides that it has glands inside the five stamens. 



Examining with a pocket lens, some flowers of the chickweed, 

 between two and three o'clock in the afternoon early in May, I 

 noticed the glands had secreted an enormous amount of liquid. 

 The little globules were nearly as large as ordinary pin heads. 

 It did not occur to me, at that time, that the period of the day 

 had anything to do with the phenomena, but I w'as led to ex- 

 amine other allied species of plants the next day. I did not detect 

 any, and I particularly examined Cerastiiim viscosum and had about 

 concluded that the existence of prominent glands and a free exudation 

 of liquid was peculiar to the chickweed, when, examining about the
