| Psiguria pedata - female flower | Psiguria pedata - fruits | this slightly older individual doesn't show the leaf variation seen above |

|
| Psiguria bignoniacea male flower | Psiguria bignoniacea inflorescence with Heliconius sp. butterfly pollinator (notice the long peduncle) | Psiguria bignoniacea leaf; very large, glabrous, and coriaceous |
|
|
|
|
| Psiguria bignoniacea male inflorescence; notice the scars on the peduncle from previous flowers | Psiguria bignoniacea fruits are small pepos | Psiguria bignoniacea growing in the greenhouse at the University of Texas at Austin |

|
| another Psiguria bignoniacea leaf | another Psiguria bignoniacea male inflorescence | top view of a Psiguria bignoniacea female flower |
|
|
|
|
| another Psiguria bignoniacea male flower | this is the habit of the Psiguria bignoniacea specimen collected in Costa Rica | another Psiguria bignoniacea inflorescence with Heliconius sp. butterfly pollinator; yes, that's pollen on the proboscis |
|
|
|
|
| the tendrils on Cucurbitaceae plants emerge laterally to the leaf petioles as shown on this Psiguria bignoniacea | Psiguria bignoniacea ovary section; the female flowers are very rare compared to the male flowers | Psiguria bignoniacea vine from the greenhouse that became my herbarium specimen |
|
|
|
|
| Psiguria racemosa inflorescence (notice the slight pubescence) | Psiguria racemosa leaf; notice the long peduncled inflorescence in the picture - both very large | Psiguria racemosa laterally-emerging tendril |
|
|
|
|
| Psiguria racemosa habit in the greenhouse at Brackenridge Field Laboratory, UT Austin | Psiguria racemosa flower | greenhouses on top of Patterson building at the University of Texas at Austin |
|
|
|
|
| Psiguria umbrosa flower | Psiguria umbrosa leaf; much more membranous than many other species of Psiguria | unopened Psiguria umbrosa flower; notice the flask-shaped calyx |
|
|
|
|
| Psiguria umbrosa inflorescence | Psiguria umbrosa inflorescence with loooong peduncle; notice the many scars of flowers gone by | more Psiguria umbrosa leaves |
|

|
| Psiguria umbrosa habit in the greenhouse at the University of Texas at Austin | Psiguria umbrosa flower longitudinal section | Psiguria umbrosa tendril |
|
|
|
|
| Gurania costaricensis inflorescence; long orange sepals, and short yellow petals that, at first, appear to be anthers | individual Gurania costaricensis flower | Gurania costaricensis leaf; notice the pubescence |
|
|
|
|
| Gurania costaricensis vine | Gurania costaricensis flowers; notice the pubescence | greenhouses on top of Patterson building at the University of Texas at Austin |
|
|
|
|
| Psiguria sp. nov. inflorescence (some call it P. tabascensis) | Psiguria sp. nov. has large glabrous leaves like P. bignoniacea, but they are not as deeply lobed | Psiguria sp. nov. (view from top); inflorescences are indeterminate |
|
|
|
|
| Heliconius sp. - Psiguria pollinator | Psiguria sp. nov. male flower | Psiguria sp. nov. vine |
|
|
|
|
| Psiguria warscewiczii petals - this is from the specimen I collected in Costa Rica (2005) - the rain destroyed the flower before I had a chance to photograph them | Psiguria warscewiczii inflorescence - this is from the specimen I collected in Costa Rica (2005) | Psiguria warscewiczii leaf - glabrous, coriaceous, wet! |
|
|
|
|
| Psiguria warscewiczii male flower longitudinal section - notice how the anthers fill the calyx tube | Psiguria warscewiczii tendril (the tendrils on Cucurbitaceae plants emerge laterally to the leaf petioles) | Psiguria warscewiczii vine |
|
|
|
|
| Psiguria warscewiczii male flower cross-section; the pollen had already been harvested by the butterflies | Heliconius sp. with pollen covering its proboscis | Gurania insolita has glabrous but membranous leaves and a strikingly-different inflorescence than Psiguria |
|
|
|
|
| Gurania insolita flowers | Gurania insolita fruits and female flowers | Gurania insolita leaf looks a lot like Psiguria!! |
|
|
|
|
| another Gurania insolita inflorescence | Ibervillea lindheimeri flower | Ibervillea lindheimeri leaves have a lot of variation |
