Philodendron, of the common roadside variety; I love the nearly-red variegation on the leaf surfaces, with the white-white venation.
Maranta, with a pattern that I like better than other available specimens; this has purple ventral surfaces with a pale pink reflection of the pattern.
Guzmania of some description; they only have these striking red stripes as young plants; the mature ones are solid green which was rather disappointing, really.
Caladium steudnerifolium - speckled form; there's apparently also one that develops stripes along the ribs, but I haven't found one yet.
Caladium clavatum - this will officially be described in September; it's an Ecuadorean native.
Draceana 'Lemon-Lime' living fenceposts. I love how the basal leaves are persistent here; my potted dracs never did that.
Philodendron pastazense - only in Pastaza province, you say? These have red-white variegated undersides as well.
Pleurothallis spp - love the spotting, really.
