First record in 1756: Dr. Smith, Hist. of Kerry, p. 382, 
No. 98. “ Tithymalus Hybernicus, Merr. Pin. Irish spurge, 
called Makinboy, or knotty rooted spurge, common on the 
mountains of this county.” Writing in 1804, Wade states 
that “it grows in immense quantities on the public road 
between Cork and Killarney and all about Killarney ”’: 
Wade Rar. It was, however, known to occur in Ireland as 
long ago as 1650, as it appears, without any locality, under 
the name Tithymalus hibernicus in How’s Phytologia Brit- 
tanica. It is mentioned also in Ray’s Synopsis, 2nd Hd. 1696, 
as found “in Hibernia.” 
This characteristic Kerry plant is no doubt one of the 
survivors of the Lusitanian invasion which reached Ireland 
probably in pre-glacial times. Unlike some of its companions, 
it is not quite confined to Ireland in the British Isles, being 
found in two or three localities in the south-west corner of 
England. In Kerry this Spurge is one of the most abundant 
of all Watson's Atlantic group of plants, its bright yellow- 
green tufts forming quite a feature in the vegetation of 
many of the upland glens and river sides in edrly summer. 
The distribution of this plant in the Dingle peninsula is 
very peculiar. It appears to be quite absent from the Slieve 
Mish range west of a line joining Blennerville with Milltown 
and from both sides of the peninsula for a distance of about
