Herbarium. A fresh spike sent by W. Wilson Saunders, Esq. 
Inspection and description of the living plant in October, 1867. 
Notres.—I may add a few remarks. The artist has represented 
the inflorescence as scarcely longer than the leaves. My original 
specimens both showed the inflorescence exceeding the leaf by 
the whole of the floriferous part. The sketch kindly sent by 
W. Wilson Saunders, Esq., shows just the same length and 
proportion to the leaf. It is highly curious that there is a second 
plant much hke this species and having entirely its appearance ; 
the whole difference is that the sheaths are closely covered with 
spiny bristles, that the inferior sepal has two straight teeth, the 
tepals are nerveless, and the lateral laciniz of the rostellum are 
rhomboid. Let me add that the flowers are deeply purplish, the 
leaf shorter, smaller and blunt. It may be introduced thus :— 
PLEUROTHALLIS ANTHOCTENIUM, n. sp., simillima P. floripectini, vaginis 
laxioribus echinatis, ostiis amplis valde echinatis, folio cuneato 
oblongo obtuso brevi, inflorescentiis plus duplo longioribus, 
floribus omnibus in parte superiori transversis, sepalo superiori 
oblongo triangulo trinervi, sepalo inferiori ligulato apice recte 
bidentato binervi, tepalis minutis ovatis enerviis, labello cordi- 
formi obtuso trinervi, column brachiis lateralibus oblique 
rhombeis. 
It probably comes from San Domingo. I found it in the 
herbarium of the Richards (now of M. Prillieux) with the note 
“S—D.” Is it from L. C. Richard, or from Poiteau ?

We grow this charming little plant in the warmer part of the 
temperate house, where it produces its delicate flower spikes 
freely, placed on a mossy block of wood. I obtained my speci- 
mens of this plant from M. Linden, of Brussels. The way in 
which the flowers are arranged in a dense spike, so regularly 
placed as to look like a miniature comb, is very pleasing.—
