N interesting little Orchid, with Pleurothallis-like habit and spikes of 
ochreous-red flowers, was exhibited by Messrs. Sander & Sons, St. 
Albans, at the R.H.S. meeting held on October 12th last. Its resemblance 
to Pleurothallis platyrachis, Rolfe (Bot. Mag., t. 7129) at once caught the 
eye, but the scapes were not flattened. A search for the name revealed the 
fact that both the plants mentioned belong to Krenzlinella, a small genus 
not yet known among cultivated Orchids. The name was given by Kuntze 
to an Ecuadorean Orchid that was collected by Consul Lehmann, and 
described in 1899 under the name of Otopetalum Tungurague (the change 
of name being necessary because there was an earlier genus Otopetalum, 
a Javan plant belonging to the Apocynacez). An unnamed specimen of 
this has been found in Lehmann’s Herbarium, and a comparison shows 
that all the three plants mentioned are identical in structure, thus affording 
an opportunity to clear the confusion up. 
In 1884 a Costa Rican Orchid, that had been collected by Mr. E: 
Shuttleworth, was sent to Kew by Messrs. Shuttleworth, Carder & Co. as 
Masdevallia sp. Soon afterwards it threw up a spike of flowers, which were 
quite anomalous in structure, and no name could be- found for it. 
Four years later, when the plant was well developed, it was described 
under the name of Masdevallia platyrachis. It was remarked: “ This is a 
hew and very remarkable species of Masdevallia, and one which presents 
such a series of anomalous characters that it appears to constitute a totally 
hew section of the genus.’’ Masdevallia then included the curious plants 
with inverted flowers now referred to Scaphosepalum, and the resemblance 
of M. platyrachis to them was pointed out, though the flowers were not 
inverted. Some time later, when the genus Scaphosepalum was revised, 
M. platyrachis was referred to Pleurothallis, where, however, the position 
was still anomalous. 
In 1899 the genus Otopetalum was described. It was said to be an ally 
of Bulbophyllum section Didactyle, differing, however, in the absence of 
pseudobulbs, and in having bilobed petals, somewhat resembling those of 
Certain Habenarias. The plant was called O. Tungurague, from the fact 
that it was discovered at the foot of Mount Tunguragua, on the Ecuadorean 
Andes. It was afterwards transferred to Pleurothallis, by Schlechter, and 
two additional species were described from dried specimens. 
The affinity of the genus is with Scaphosepalum, the habit being very 
Similar, also the two pyriform pollinia, but the flowers are not inverted, and 
the petals are obliquely auricled at the base, the two auricles being situated 
behind the column, and slightly clasping it, while the strongly recurved lip
