ST. JOHN: SABLE ISLAND. 59 



of a specimen of Juniperus Sabina procumbens (creeping juniper). 

 It was rooted in a layer of black soil and when taken out showed 

 that it had lain flat on the ground. Two of the roots, including the 

 bark, measured 3*^6 and 3% inches in diameter respectively, while 

 the crown, where the branches began to spread was over seventeen 

 inches in circumference or nearly six inches in diameter." Quite 

 common on the old land, J. Macoun (C. no. 22,607); trailing on the 

 sand dunes, Whalepost, H. St. John, nos. 1,116 and 1,117 (H). 

 FL, Fr. August and September. 



[J. PROCUMBENS recorded by J. Macoun (M. p. 218A) is probably 

 J. horizontalis.]

Typha latif olia L. Local, growing only by the border of the fresh 

 ponds at the east end of Wallace Lake, J. Macoun; and swampy 

 edge of fresh-water pond near Life Saving Station No. 3, H. St. John, 

 no. 1,118 (H).

SPARGANIACEAE. 



Sparganium angustifolium Michx. Common in the perma- 

 nent fresh-water ponds. J. Macoun (C. nos. 22,637 and 22,637a);

 POTAMOGETONACEAE. 



Potamogeton polygonifolius Pourret. Abundant in the fresh- 

 water ponds. It will grow even in ponds that dry up for a part of 

 the summer, but it probably does not fruit in these except in a wet 

 season. In such exsiccated ponds the plant appears as a tight pros- 

 trate rosette of apparently sessile leaves. J. Macoun (C. no. 22,095) 

 for the first notice of this, see A. Bennett, Journal of Botany, xxx. 

 198 (1901). H. St. John, nos. 1,121 and 1,122 (H).
