Photographs of Psiguria and related sister species included in

"Systematics and Biogeography of Psiguria (Cucurbitaceae)"

Please note:  I am currently studying the taxonomy and systematics of Psiguria.  Some of these species names may turn out to be incorrect or synonymous with other species names.  Check back for updates and revisions.

Psiguria pedata (putative name) - mature leaf	Psiguria pedata - showing lateral tendrils	Psiguria pedata with male flower
Psiguria pedata - male inflorescence	Psiguria pedata - longitudinal section of the male flower	the young leaves exhibit quite a variation of complexity and shape
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
Ibervillea lindheimeri  fruit	Heliconius sp. laying eggs in the greenhouse on top of Patterson building at the University of Texas at Austin	Heliconius sp. laying eggs in the greenhouse on top of Patterson building at the University of Texas at Austin
