ally catalogued under this name is a species of Cypella. 
POINCIANA GILLIESII. A synonym of 
Cesalpinia Gilliesii (which see). 
POINTING-IN. When applying chemical or other 
manures to land which is full of roots, it is necessary 
to merely point them in with a fork. The roots thus 
receive immediate benefit, without injury, as would be 
the case if such manures were dug in with a spade or 
other sharp implement.

POISON BULB, CAPE. See Brunsvigia 
ee (the correct name of which is now Buphane 
disticha). 
POISON ELDER. Sce Rhus venenata. 
POISON NUT. See Strychnos Nux vomica. 
POISONOUS PLANTS. A number of plants, both 
hardy and tender, are more or less poisonons, and need 
to be handled with care, or serious results may ensue. 
To enumerate a few, Euphorbias, Oleanders, Poinsettias, 
and Hippomane Mancinella. The sap of these has had 
very injurious effects on gardeners with cuts or wounds 
on their hands. Another extremely poisonous genus is 
Rhus, and simply handling species like venenata and 
Towicodendron has caused great swelling of the limbs. 
Then there are plants which, if not poisonous in the 
strict sense of that term, cause trouble by means of the 
irritant hairs. Primula obconica, to wit, causes skin 
eruptions on many people. Then several bulbous plants 
are highly poisonous—the common Meadow Saffron 
(Colchicum autumnale) and Buphane towicaria are good 
examples.
