ROSACEA. 243 



which partake of the characters of both, approaching sometimes more 

 nearly to the one, sometimes to the other. They have been described 

 as a species under the name of G. intermedium, but they are more gene- 

 rally believed to be mere accidental hybrids between the two species. 



Y. RUBUS. KUBUS. 



Herbs, with a perennial stock, or more frequently weak, scrambling, 

 prickly shrubs ; the leaves pinnately or palmately divided into dis- 

 tinct segments or leaflets, or rarely simply lobed. Calyx free, 5-lobed. 

 Petals 5. Stamens numerous. Fruit a kind of granulated berry, 

 formed by the union of numerous 1-seeded succulent carpels round the 

 conical or shortly oblong, dry receptacle. 



A large genus, widely distributed over almost every part of the globe. 

 The fruit, analogous in some respects to that of a Mulberry, is suffi- 

 cient to distinguish it at once from all other Rosacece. In the Mulberry 

 however each granule is formed by a separate flower, whilst in Rubus 

 the whole fruit proceeds from a single one. From the Strawberry it 

 differs in that the carpels are succulent on a dry receptacle, whilst in 

 the Strawberry the carpels are dry, and the receptacle succulent. 



Flowering stems biennial or perennial, woody at least at the 

 base, 2 or more feet long. Stipules subulate. 

 Lower leaves pinnate, with 5 leaflets. Rootstock creeping 1. Raspberry R. 

 Leaves of 3 leaflets, or, if of 5, the 4 lower proceed from 

 the same point. 

 Branches slender, glaucous. Fruit covered with bluish 



bloom 3. Dewberry R. 



Branches not glaucous. Fruit black, without bloom . 2. Blackberry R. 

 Flowering stems herbaceous, very short, or seldom a foot 

 high. Stipules ovate or lanceolate. 

 Leaves with 3 leaflets. Flowers small, axillary .... 4. Stone R. 

 Leaves undivided. Flowers large, terminal, solitary . . 5. Cloudberry R. 



The Virginian Raspberry, often cultivated in shrubberies, is the 

 R. odoratus from North America. The Arctic R. (R. arcticus, Eng. 

 Bot. t. 1585), a low plant, with a creeping rootstock, and short herba- 

 ceous stems, like the Cloudberry R. f but with 3 leaflets and pink 

 flowers, has been inserted in our Floras as having been found in the 

 Scotch Islands, but this appears to be a mistake. At any rate, all 

 recent search for it there has been in vain.
