292 FLORA OF THE EXTREME SOUTH OF DEVON. 



foliage-leaves are not in series with the scale-leaves, but successive 

 pairs of foliage-leaves primarily decussate ; tliough subsequently, 

 owing to changes in the x^rogress of develoxnnent, they are set on 

 at a wide acute angle. 



The peculiarity then in the arrangement of the leaves is this — 

 the foliage-leaves are always produced as the first pair of leaves on 

 lateral shoots arising in the axil of scale-leaves, and these shoots, 

 as they elongate, thereafter produce only scale-leaves. I know of 

 no instance of a similar arrangement. 



The second point to which I wish to refer is connected with the 

 morphology of the part of the flower. 



The flowers are unisexual. The male flower consists of three 

 stamens, connate by their filaments, and surrounded by a tripartite 

 perianth, the segments of which alternate with the stamens. In 

 the female flower three carpels are combined to form a one-celled, 

 many-ovuled ovary, and the segments of the tripartite perianth 

 alternate with the carpels. 



The position of parts renders it probable that we have here a 

 case — similar to that of Salix amongst Dicotyledons — of the same 

 phj'llomes forming carpels in one flower and stamens m the other. 

 But whilst analogy supports this supposition the explanation is 

 conceivable that wdiilst in the female the inner perianth of the 

 typical monocotyledonous flower is present with the three carpels, 

 in the male the outer x3erianth-whorl coupled with the inner 

 staminal row, is reiDreseuted. 



SOME NOTES ON THE FLOKA OF THE EXTREME 

 SOUTH OF DEVON. 



By T. R. Archer Briggs, F.L.S. 



I HAVE recently spent a few days in investigating the botany of 

 the portion of S. Devon that lies between Bigbury Bay on the west, 

 and the Start Point on the east, and forms the bold stretch of land 

 projecting into the English Channel on each side of .the inlet 

 running up to the town of Kingsbridge, and terminating on its 

 Avestern and eastern sides in the respective headlands of Bolt Head 

 and Prawlo Point. Comj^aratively little has been done by the 

 botanist in this i^art of Devon, though its flora is of peculiar 

 interest from the land being the most southerly in the county, and 

 such of it as lies south of a line drawn from the village of Hope, a 

 little north of Bolt Tail, to Hall Sands, near the Start Point, being 

 on mica slate and gneiss. Eocks of similar formation do not occur 

 elsewhere in the county, tliough they reappear in the adjoining one 

 of Cornwall, to the south of the serpentine, at Lizard Point. My 

 examination of the tract lias been of too incomplete and cursory a 

 nature to allow me to attempt anything like a full account of tlie 

 plants growing in it. What I aim at doing in this paper is to 

 name, mil sometimes give particulars respecting, the rarer or
