JUNE. 239 



more or less abundantly covered with glands below, though 

 sometimes entirely smooth, except the midrib. Flowers aggre- 

 gate, elevated on long smooth general stalks supporting a leafy 

 bractea and several bunches of flowers, the exterior ones of which 

 are elevated on smooth stalks with smaller bractsea in a similar 

 manner. The real peduncles are very setose, as is the tube also, 

 though occasionally almost quite smooth even on the same gene- 

 ral umbel. Flowers varying in the bunches or umbels from 2 to 

 to 14. Scent fragrant. 



8. R. SEPTUM. Bushy Sweet-briar. Leaves slightly sweet- 

 scented, their leaflets broadly ovate, hairy beneath, the petioles 

 and midribs of leaflets excessively crowded with glands. Calyx 

 persistent, and reclining on the half-ripe almost globular setose 

 fruit, the sepals elongated, with leafy points. This is a rare local 

 species. It is mentioned in HOOKER'S Flora, as found only in 

 Warwickshire and Oxfordshire. I have gathered it at Little 

 Malvern, Worcestershire, and in Caernarvonshire. 



The broad leaflets crowded together, and numerous flower- 

 stalks give this rose a very different aspect to rubiginosa, its 

 nearest affinity. 



9. R. MICRANTHA. Small-flowered Sweet-briar. Leaflets 

 small, acute, doubly serrated, hairy and glandulose beneath. 

 Fruit small elliptical, with extended neck, slightly setose, the 

 sepals glandulose, deciduous. Abundant on limestone or chalky 

 hills. 



The smaller flowers and more delicate aspect of this sweet- 

 briar well distinguish it at sight from R. rubiginosa, and the 

 fruit is also characteristic. Vars. occur with smooth peduncles 

 and fruit. 



ii. With leaves generally deficient of glands. 



10. R. CANINA. Common Dog-rose. Leaves naked scentless, 

 the sepals pinnate deciduous, fruit quite smooth. Plentifully 

 diffused. 



Numerous varieties of this rose occur which certainly deserve 

 distinction, but it may be questionable whether as species or not. 

 Typically the leaves of canina are quite naked, but in the vars. 

 dumetorum and Forsterl, they are more or less hairy. These
