ngraecum articulatum is one of the numerous discoveries of the Rev. 
W. Ettis, in Madagascar. On his return from his second missionary 
visit to that island, he brought home two living plants, which he 
cultivated at his residence, Rose Hill, Hoddesden, Herts. The species was 
described by Reicuensacn, early in 1872, from materials forwarded to him 
by Mr. Extis in the autumn of the previous year. This was probably not its first 
time of flowering, as Rricuenpacu remarked that the plant appeared to indulge 
in endless caprices in the production of polymorphous flowers, and that the spur 
was very variable, as he had seen it three times as long as the ovary, while in 
other cases it only equalled, or was even shorter than this organ. Probably 
these abnormal flowers were only borne at first, before the plant became properly 
established. 
The plants in question afterwards passed into the collection of the late 
Mr. Joun Day, of Tottenham. For many years the plant continued very He, 
but now, owing to the numerous importations of Madagascar Orchids which 
have been made, it has become more widely diffused in cultivation. 
It is allied to A. Ellisii Reus. F., but is readily distinguished by its
