coloured flowers in clusters. The Boursaultian Rose is of a 

 fine colour : the flowers are in clusters, and much es- 

 teemed. The Microphylla has very delicate foliage ; but I 

 have not seen its flowers, as it has only been introduced into 

 this country the present season, when I paid a guinea for a 

 small plant of it. The Bichania Rose is curious, as the edges 

 of the petals turn white after being sometime expanded. The 

 climbing, or running roses, suitable to train against build- 

 ings, or on arbours, bowers, 8cc. are the following : Com- 

 mon Multiflora, Roxburgh's White Multiflora, Lady Banks' 

 Double White, Greville's Superb, Champneys, Noisette, 

 Boursaultian, Hybrid, Macartney's, 8cc. There are a few 

 varieties of the China rose that require winter protection in 

 this latitude, which are designated in the catalogue, but I 

 consider that even these will not require that attention south 

 of the Potowmac. 



Yucca. Of this very curious genus there are several spe- 

 cies which are already cultivated considerably as hardy or- 

 namentals in our gardens, and doubtless some others will 

 equally withstand the rigours of winter. 



Yucca JUamentosa, or Adam's Thread. This is in our vi- 

 cinity the most common, and has long lanceolate leaves, 

 pointed at the ends, with numerous threads on both edges, 

 and which attain to a considerable degree of strength; the 

 leaves are spread near the ground in a radiate manner, and 

 remain during the winter. In summer the plant throws up 

 a flower stem to the height of six or eight feet, which 

 branches somewhat at its summit, and is garnished with 

 numerous tulip shaped while flowers, which give to the 

 plant a striking appearance. After these are past, the shoot 

 which produced them dies away, and is replaced by another, 

 which springs up in the course of the season from the same 

 root. There is a most beautiful variety with variegated 

 leaves. 



Yucca Jlaccida^ or Flaccid Thready. This at first sight 

 much resembles the foregoing, from which, however, it may 

 easily be distinguished, the leaves of the former being more 

 stiff and upright. On this they are quite soft and flexible, 

 somewhat glaucous on the under side, and the filaments less 

 numerous; the flower stem does not attain to near the 

 height of the preceding one, seldom rising over three or 

 four feet ; the flowers are very similar, but as this species 

 throws up more suckers from the root than the preceding, it 

 has generally more flower stems, and makes a fine show. It
