Vaccinrum rugosum. Hook. et Thoms. Ms. 
This remarkable and beautiful plant was originally detected 
by Griffith in the temperate regions of the Khasya mountains, 
where it has since been gathered by Drs. Hooker and Thomson, 
who have distributed it in their Indian Herbarium under the 
name of Vaccinium rugosum. It was also found by Dr. Hooker in 
the Sikkim-Himalaya mountains, and by Mr. Booth in the 
Bhotan Himalaya. The plant here figured was sent by Mr. 
Thomas Lobb to Messrs. Veitch and Son, with whom it flowered 
in May of the present year. It succeeds well ina common green- 
house. At Tab. 4910 will be found figured another species of 
this genus, together with some observations on its congeners, in- 
cluding this. The beautiful transversely fasciated colouring of 
the corolla on a white ground, exactly recalls that of the Thibau- 
dia macrantha (Tab. 4566), but the colour of the flower probably 
varies, as we find that it is described in the notes to the wild 
specimens as varying from deep-red to purple. 
Descr. A glabrous shud, often epiphytical, forming a large 
tuberous rhizome or caudex on the trunks of lofty trees. Branches 
covered with circular pale pustules. Zeaves almost sessile, sub- 
cordate at the base, very coriaceous and rugose, almost lacunose 
on the under surface, lanceolate or ovate-lanceolate, acuminate, 
serrate, deep bright-green above, pale beneath, the young ones
