In tlu! r_vpic;il loi-in the articidi ure compactly arranged and their 

 form is liighiy regular : those of the ui)j)er portions have the lobes 

 projecting obli({ue]y upwards but gently turning into transversal 

 direction. The former articuli, therefore, assume a form just like the 

 wings of an acer fruit or a dock key; and the maximum breadth 

 measures 4-() mm., the inter-ofeniculai- distance l.ô-2.() mm. The 

 outline of a branch is without exce})tional spathulate. The lower end, 

 or the pedicel, as it were, of an up[)er or middle ai-ticulus is always 

 prominent as in a Ijamboo node, but gently disappearing as we trace 

 downwards. The conceptacles are generally immersed in the upper 

 margins of the lobes. 



The /. (iittßiüta has a similar character, but narrower articuli : 

 Th(; breadth measui-es 2. 0-2.0 mm., the inter-genicular distance 

 1.5-2.0 mm. The conceptacles are immersed in the middle parts of 

 the lobes and seldom at the apexes.

 they are not sharply defined and we are afraid of confusing them more 

 and more by :ip])lying oiu- ])lant to eithei' of them until we have had 

 an authentic specimen to refer to.
