The meaning of the name of this genus has been 
noticed under No. 316. Mackayanus has been 
adopted as a specific name, out of respect to Mr. 
Mackay, Curator of the Trinity College Botanic 
Garden, Dublin, a veteran in the science of Botany 
and Horticulture, and an industrious labourer in 
the interesting field of Irish indigenous botany. 
JMr. JMackay received seeds of this Pentstemon 
from Drummond, who discovered it at Ohio, in 
1 834. One of the plants, raised from such seeds, 
was sent to Mr. Cameron, of the Birmingham 
Garden, who has fortunately preserved the species; 
— the whole of the plants in the Dublin Garden 
having perished in the winter of 1837-8. We can- 
not help dropping a remark or tw^o by the way. If 
there be a cultivator who does not experience 
gratification in distributing the riches of his gar- 
den, (which we hope there is not, but of which 
experience forbids us to deny the too frequent 
occurrence,) let him here draw a hint from the fact 
mentioned, that had not a single plant been given 
away, whilst it was thus rare, and consequently 
valuable, the whole stock might have been lost.
