shape, as well as many others of the same genus, bearing a re- 
semblance to the ear of an elephant ; beneath they are of an uni- 
form red colour, and above of a fine deep green, with numerous 
spots, white and shining like silver ; which gave rise to the spe- 
cific name that first appeared in the Hortus Gorenkensis of Dr 
Fischer. These curious spots, though they have been supposed 
by some to be inconstant, are found to be quite otherwise, as 
seedling plants possess them even in a more striking degree than 
old ones. The silver-spotted Begonia us a native of the Brazils; 
and, from the facility with which it is increased, bids fair to be 
soon one of the most common, as it is one of the most beautiful 
inhabitants of our stoves. 
T. 1 9. Orontium aquaiicum , a hardy North American plant, 
of which no previous figure existed, that we know of, save the 
miserable one in the Amoenitates Academic re. 
T. 20. a new and very singular species of Cactus , C. trun- 
ks, which blossomed, for the first time in this country, at the 
Boyal Botanic Garden of Glasgow, N and shortly after at the 
garden of Liverpool. It is, like the rest of that family, leafless ; 
the stems jointed ; the joints singularly compressed, and trun- 
cated at the extremity ; the flowers are large, handsome, and of 
a deep rose colour. 
T. 21, 22, and 23, represent three species of Peperomia , viz. 
blanda , quadrifolia and polystachya. The genus was long con- 
founded with Piper , but was separated by Humboldt and Kunth, 
because differing in the number of stamens, in the configuration 
of the stigma, and in the habit of the plants. There are some 
interesting general remarks upon the two genera, extracted from 
that learned but costly work of Humboldt’s, the Nova Genera et 
Species Plantar urn, and given under Peperomia, blanda. 
T. 24. Velleia lyrata of Mr Brown’s Prodromus, a very 
pretty plant, with yellow blossoms, and belonging to the Natu- 
ral Order Goodenovue of Brown. 
At t. 25. we have a second species of Doodia , D. caudata (D. 
aspera being figured at t. 8. of Part 1.), a delicate fern, inha- 
bitant of Port Jackson and Van Dieman’s Land, but not yet 
cultivated in our gardens. 
T. 26. Caladium bicolor , a handsome and well-known inha- 
bitant of our hot-houses, remarkable for the rose-coloured tint
