The same species in hb. Kew, from CoLomsia. 
2. MICROPLEURA. 
Micropleura, Lag. Obs. Aparasol. p. 15; Benth. et Hook. Gen. Plant. i. p. 878. 
The only known species :— 
1. Micropleura renifolia, Lag. Obs. Aparas. p. 15; DC. Prodr. iv. p. 71. 
Hydrocotyle? grumosa, DC. Prody. iv. p. 70; Calques des Dess. Fl. Mex. 426. 
SoutH Mexico, region of Orizaba, Escamella (Bourgeau, 2932; Miller, 1097), woods 
on the mountains of the Pacific coast of Oaxaca, 6000 to 7000 feet (Galeotti, 2752) ; 
GuaTEMALA, Barranca del Incienso (Bernoulli, 289). Hb. Kew. 
There seems to be no doubt that the Mexican plant is the same as that described by 
Lagasca, though he records it as a native of Chiloe. It also agrees exactly with De 
Candolle’s tracing of Mogino and Sessé’s figure quoted above, and should, we think, be 
referred to Hydrocotyle. 
Tribe MULINEA. 
There are nine genera of this tribe, chiefly South-American, but also represented in 
South Africa and Australia. There are none in the northern hemisphere, except the 
Mexican and one species in the Canary Islands.
