PLANTS 1-UI:ND IN KEIIRY. Ill
Jitncus tenuis Willd., au addition to the Irish Flora, was the
most interesting plant found ; a note on its occurrence and
locahties will be found in Journ. Bot. 1889, p. 335.
Xid'lla (jracilis Agardh, is also most probably an addition to our
Flora, its only claim to be considered Irish having hitherto been
the unsatisfactory record, " Glencree, D. Orr," where it has not
been found subsequently. I gathered this minute plant, growmg
with Xaiiis jlcxilis, Xitrlhi tnnislueeiis, and .Y. jle.vUis, at the south
end of Caragh Lake ; it came up in some abundance on the mud
adhering to the prongs of a small dredge kindly sent to me by the
Messrs. Groves, which I found most useful.
Scirpus jiarculus R. & !S., was discovered growing in great abundance
along the tidal portion of the River Casheu, above Cashen
Bridge. This lind was the more welcome, since the only other Irish
locality for this Scirpus was the mouth of the Avoca River, Co.
Wicklow, where I fear the plant has been completely destroyed by
the new harbour-works.
A most unexpected plant found last summer was Poli/i/onuui.
(irifoliuin L., a native of Canada and the United States, in low
grounds. I am not aware of this plant having hitherto been
recorded among British aliens. This desperately prickly Poli/-
(jiinuni. was growing abundantly on the dry stony bed of a small
stream at Castle Cove, on Kenmare Bay, about six miles east of
Diirrynane. It occurred within a few hundred yards of the sea,
just iibove tidal influence, and below a small pool apparently used
fur washing clothes by the few cottagers in the neighbourhood.
The I'vlijiiunum was usually but a few inches in length, but some
of the plants I gathered had branches over a foot long. I find it
hard to account for the presence of this small annual here.
Tillage is rare in the neighbourhood, and neither mills nor harbour
near ; however, my further investigations here were cut very short
by a drenching thunderstorm.
Siiiu't/iis hicular Kunth. I was glad to find that this plant has
a wider range than had hitherto been supposed. I found the
Sinict/iis in many spots between Darrynane, its recorded locality,
and Reenronee, a small point in Kenmare I'ay, some eight miles
further east; it also occurred more than a mile inland, about halfway
between these points ; while about Darrynane it extends frona
Lamb's Head on the south, to Sheehan's Point on the north, with
many intermediate localities.
This extreme south-west corner of the county seems also to bo
the head-quarters of Mirrucala Jilifunuis and Curcx punctnta, both
of which arc very abundant here, though the iJarex is almost
restricted to Kenmare Bay.
rHularia i/lobulij'era L., new to the south of Ireland, was also
found last summer, growing sparingly in a few inches of water in
the Upper Lake, Killarncy.
As to the Kerry Potamogetons of 1889, I have again to thank
Mr. Arthur Bennett for his kindness in looking over several
pu/.zling plants. Among tlicse was a large gathering of the
