Famity IV.—GROSSULARIACEAE. GoosEBERRY FAMILY 
This family contains only the single genus, Ribes, gooseberries. 
The species are all shrubs with alternate leaves which are, how- 
ever, often in groups or fascicles. The leaves are broad and 
generally deeply cut by sinuses which divide the blade into 3 or 
4 lobes. At the base of the leaf stem are two small stipules. The 
stems are, in some species, armed with sharp spines just below the 
leaf axils, in other species the spines or sharp bristles are dis- 
persed along the stem, while in some the stems are entirely desti- 
tute of spines or of bristles. The flowers are, in some species, 
solitary or in groups of 2 to 4, while in others they are numerous, 
arranged along a main flower stem in a long slender cluster 
(raceme). At the base of each small foot-stalk for the flower is 
a small bract. The calyx has 4 or 5 sepals, sometimes colored; 
petals 4 or 5, generally 5, inserted into the throat of the calyx; 
they are small, usually less than the sepals. There are 5 stamens 
and 3 styles which unite at base into a one-celled ovary. The 
fruit is a berry containing several seeds.
