to the species of Daubentoniopsis instead. Pollard, 6 following De Candolle's 

 and Watson's interpretation of Cavanilles' plant, was of the opinion that 

 this, being the first one described, should retain the specific name longifolia, 

 and therefore proposed the name S. mexicana Poll, for Ortega's plant. As 

 the two are the same, he merely added a new synonym to our species of 

 Daubentoniopsis. The yellow-flowered Daubentonia is still nameless. 



ii. Daubentonia DC. Mem. Leg. 285. 1823 



Shrubs or trees, having abruptly pinnate leaves, with many leaflets and 

 deciduous stipules. Flower in axillary racemes, resembling closely those of 

 Sesban, but the calyx-lobes are still smaller, the calyx-tube being merely 

 undulate on the margins, slightly ciliate at the teeth. The banner is without 

 callosities, and the wings and keel-petals are without basal auricles. The 

 pod is more or less 4-angled, but somewhat compressed. The endocarp is 

 membranous and constricted around the seeds, the exocarp more or less 

 spongy, the sutures are thick, each produced into two sharp ridges or wings. 

 The seeds are reniform.

The type of the genus is D. punicea (Cav.) DC, based on Piscidia 

 punicea Cav. 



The genus consists of about half a dozen species, of which 3 are natives 

 of South America, one of the southern United States and northern Mexico, 

 Daubentonia Drummondii Rydb. {Daubentonia longifolia? T. & G. Fl. N. 

 Am. 1 : 293. 1838), and I or 2 of Mexico. I have based it on D. longifolia? 

 T. & G., rather than on D. longifolia DC, in part as to description, for that 

 name really belongs to Daubentoniopsis longifolia, as stated before. One of 

 the South American species, D. punicea, has also been found introduced in 

 Florida and Mississippi. 



12. Glottidium Desv. Jour. Bot. 1: 119. 1813 



Annual herbs, having abruptly pinnate leaves, with many leaflets and 

 deciduous stipules. The flowers are in axillary racemes or panicles. The 

 calyx and corolla are almost exactly like those of Sesban, the banner with 

 callosities, the wings and keel-petals of the same shape as those of that 

 genus. The pod, however, is different, broad, stipitate, compressed, 2- 

 valved, and 2-seeded, the valves at last separating in two layers, the ehdo- 

 carp very thin and papery, the exocarp firmer, somewhat inflated, but not 

 bladdery as in Diphysa.

 7. pod, X 2/3; 8. pod in cross section, X 1 ; 9. seed, X 2/3. 



The genus is monotypic and was based on Aeschynomene platycarpa 

 Michx., which is the same as Glottidium vesicarium (J acq.) Harper.
