ROSAGEAE. 99 
PYRACANTHA. Fire Thorn. 
(Family Rosaceae). 
Compactly branched _ shrubs, 
sometimes grown against walls or 
other supports, with very sharp 
spiny twigs: evergreen. Twigs 
rather slender, subterete: pith 
small, continuous. Buds solitary 
or collaterally branched in spine 
formation, sessile, round-ovoid, 
with some half-dozen pointed dry 
scales. Leaf-scars alternate, nar- 
rowly crescent-shaped or 3-lobed, 
somewhat raised: bundle-traces 3: 
stipule-scars minute. Leaves ob- 
lanceolate, glandular - crenulate. 
(Crataegus). 
The fire-thorn is one of the many 
Rosaceae with apple-like fruit 
which are separated into techni-. 
cally well-defined genera with 
great difficulty... Though it is 
usually considered to belong to a 
different genus from the red-haws, many gardeners still 
speak of it as Crataegus Pyracantha. Where it can be grown, 
it is an effective shrub for evergreen hedges. 
Twigs red, somewhat hairy, or glabrate. P. coccinea.
