Other species in the road that was extremely muddy in Cordillera de Cutucú were Anthurium 2003. On that occasion, we tried to breviscapum Kunth, A. croatii Madison, come down this road from Cuenca A. eminens Schott, A. harlingianum in an attempt to drive to Méndez, but Fig. 1: Possible new species of Croat, A. polyschistum R.

This year we were able to Chlorospatha pubescens Croat & make it all the way to the tunnels, so L. Hannon, Philodendron atratus Croat, I knew we had now covered the entire P. par vilobum Croat, P. plowmanii road. A new species of Anthruium sect.

After another night of pressing plants From Santiago, where we spent the and sleeplessness, listening to some night at the Hotel Intercontinental, pretty dreadful singing, we took eight we drove toward the Río Morona and bags of plants to a bus terminal and collected on Cerro Shaime, the last hill arranged to ship specimens back to before reaching the Amazon lowlands. Quito, then headed south toward From this area you can look east, into Gualaquiza, passing through Indanza the vast Amazon lowlands stretching and San Juan Bosco.

Once across the river we drove toward Numbaime on the road to the summit of the Corillera del Condór. Many signs of past military presence were apparent with camouflaged tank garages hidden off the edge of the road. The area was relatively pristine and very rich in aroids, including what appears to be a new species of Anthurium sect. Belolonchium (Fig. 4, Croat 91015). The following species were also sighted in the area: Fig. 3: Quime ferry crossing the Río Zamora, 6.8 km S of Chuchumbletza A. amoenum Kunth, A. arisaemoides Madison, A. breviscapum Kunth, small hotel near the bus terminal.
