high, -25 nun. diameter. The stalks readily separate when 

 soaked in water. The sporangia are chiefly immature. In a 

 recent gathering, which unfortunately is much damaged, the 

 sporangia are clustered or scattered ; stalks 3 • 5 to 4 mm. high, 

 0*12 to 0*2 mm. diameter, purple-brown, longitudinally 

 furrowed, attenuated upwards ; sporangium wall yellow-brown, 

 membranous; capilhtium of tubular threads, 4 to 20 /* diameter, 

 closely beset with slender spines, or smodlh, regular, 

 occasionally inflated, sometimes dividing into a brush of 

 narrow tubes at their extremities, running longitudinally 

 down the sporangium and attached to the wall about liaH way 

 down. Spores 5 to 7 ^ diameter, reticulated, brownish-yellow.

The following account of the vicissitudes of the name 

 Alwisia may obviate any change which might appear necessary 

 to one who notes the apparent confusion in its present uses. 

 Thwaites (in litt.) suggested Alwisia minuta as the name of an 

 orchid which Lindley considered was a Tceniophyllum ; this 

 species was named Tcenio'pkyllum alwisii, and Tlxwaites' 

 generic name was not made use of. But Lindley mentions 

 Thwaites' suggestion in his account of that species, and the 

 Index Kewensis cites Alwisia minuta as a synonym of Tcenio- 

 phyllum alwisii. This citation is surely an error, for the name 

 was never used, and the case comes under the rule, " Incidental 

 mention of a name is not effective pubMcation " (Vienna 

 Rules, Art. 37). The name Alwisia is therefore not pre- 

 occupied by Lindley 's reference. In 1859 Lindley named 

 another Ceylon orchid Alvisia tenuis. From this there has 

 arisen much confusion, more especially at Peradeniya. In 

 Enghsli transliterations of Sinhalese names, w and v are 

 practically interchangeable, and as the name was derived from 

 a surname which is usually written " Alwis," Thwaites always 

 refers to this orchid as Alwisia. It appears in that form in his 

 " Enumeratio," and in all the Ceylon Catalogues. Trimen's 

 " Flora of Ceylon " (as completed by Hooker) gives the correct
