A glance at this list shows at once, that there is a very marked periodicity 

 in the development of flowers and fruits, much more pronounced than in the vege- 

 tative system, a fact well in accordance with the nature of the cHmate. As a rule, 

 not one indigenous plant bears flowers in winter time. Thus it is of a certain in- 

 terest to note that several aliens which have gained citizenship in the Falklands, 

 such as Bellis perennis, Poa pratensis, Sagina procumbens, Senecio vulgaris, Veronica 

 serpyllifolia and Ulex europceus often flower during the winter also. However, this 

 also happens in their native countries when the season of rest is more mild than 

 usual. 



In order to complete the sketch of the plant associations published in this 

 paper, I shall now try to describe, in a few words, the various periods of the season 

 with regard to the appearence of flowers. 



The early spring is very poor in flowers. The first of them all are the small 

 white flowers of Draba funiculosa, which appear in September. Låter on follows 

 Empetrum rubrum, but neither these plants nor Abrotanella, Caltha sagittata, Rostkovia 

 have any power to change the desolate and monotonoas character of the landscape; 

 only at the end of October does a marked change take place, when Sisyrinchium 

 opens its beautiful, white bells. At the same time also Primula magellanica starts, 

 soon followed by Oxalis which greatly adorns the cliffs near the sea (Pl. XII). Se- 

 veral flowers, generally not noticed by the wanderer, belong to the same period, as 

 Bolax, Caltha appendiculaia, the Colobanthus-si^eGies, Drapetes, Gunnera, Luzula, 

 Marsippospermum, and Plantago barbata. The earliest grasses seem to be Poa fla- 

 bellata and HierocJiloe. At the end of November or in the beginning of December 

 many species are added, but only few of them, as Arabis, Cardamine, Pernettya and 

 Oreomyrrhis with white and Senecio litoralis, Taraxacum, Troximum and Viola macu- 

 lata with yellow flowers are of any importance; besides, the purple heads of Accena 

 are noticeable. Some never raise their small whitish flowers above the surface of
