reddish or yellowish hues. They are glandular on the margin and 
in some species on the surface also. These scales are generally 
soon deciduous. 
The flowers in our species are, with one exception, Cratae- 
gus uniflora, produced in clusters at the ends of short 
leafy terminal or lateral branches. In the earliest species to 
flower in our latitude they appear about the end of the first week 
in May, in the latest, the first week in June, making the flowering 
season about one month long. In nearly all cases the flowers open 
and their petals fall before the leaves are fully developed. The 
flower stems or peduncles may be long or short, simple or 
branched, glabrous or hairy, according to the species. The 
branching peduncles frequently support three flowers each, the 
central flower opening a little earlier than the two lateral. The 
calyx is superior and five lobed, the petals are five, the stamens 
vary from 5 to 20 and the pistils from 1 to 5. The stamens 
are normally 5, 10, 15 or 20 in any given species, but by the sup- 
pression of some or the union of two adjacent filaments such 
definite numbers are not always found. Nevertheless the number 
of the stamens is now utilized as a specific character. The color 
of the anthers may be pale yellow or whitish, pink or rosy red, 
purplish red or violaceous, and though these colors are very fleet- 
ing they are recognized as having, in many cases, specific value. 
The calyx lobes are generally tipped with a single gland, their 
margins may be entire or furnished with sessile or stalked glands. 
They are erect in bud but spreading or reflexed in anthesis and in 
some species they later become again erect or incurved. In many 
species they also become red on the inner basal surface as they 
advance in age. They are sometimes deciduous from the ripe 
fruit, specially in species belonging to the section Tomentosae. 
The petals are nearly always white in our species. In one or two 
‘they show a tendency to become rosy tinted when they begin to 
wither. They are quickly deciduous. They are sometimes eroded 
or wavy on the edge, and are generally furnished with a short claw 
at the base. 
The time of ripening of the fruit extends from the middle of 
August to the middle of October. The number of fruits in any
