A very charming Ericaceous plant of South America, but 

 from what precise locality is not known, for a living plant of 

 which we are indebted to the liberality of James Bateman, Esq. 

 This we have referred to Psammisia, rather than to TJiibaudia, 

 on account of its near affinity with Psammisia penduliflora, Kl. 

 {TJiibaudia, De Cand.), given at our Tab. 5204. Indeed, we do 

 not clearly see the reason for the formation of the genus Psam- 

 misia ; but if the genera of this Vaccineous group of PJricacete 

 are hard to determine, much more is it hard to determine the 

 limits of the species, especially since most of them are described 

 from dried specimens, when the flowers become much changed
