458 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
SPECIMENS EXAMINED: 
Mexico: Type collection. 
This comes from a locality far north of those reported for other members of 
the genus. It is related to the last preceding species; but the corolla is larger, 
the calyx lobes of very different form, and the leaflets obtuse (rather than acute 
or acuminate) and glaucescent. 
EXPLANATION OF PLATH 31.—Specimen of type collection in the U. S. National Her- 
barium. Scale 3. 
17. Cobaea stipularis Benth. Pl. Hartw. 45. 1840. 
Rosenbergia stipularis House, Muhlenbergia 4: 23. 1908.

RANGE: Southern Mexico.

The only specimen the writer has seen is one in the U. S. National Herbarium, 
grown in the Royal Botanical Garden at St. Petersburg. This has no open 
flowers, but the form of the leaves is exactly that described and figured for 
Cobaea stipularis. The species is readily distinguished by having the lowest pair 
of leaflets reduced and stipule-like. Brand?’ reports a specimen from Guayaquil, 
but it is very doubtful whether it is correctly determined. Hemsley? refers here 
Coulter’s 928 from Zimapan, Mexico, while House cites Mueller’s no. 634 from 
Orizaba. 
18. Cobaea scandens Cay. Icon. Pl. 1: 11. pl. 16, 17. 1791. 
Rosenbergia scandens House, Muhlenbergia 4: 23. 1908, 
TYyPr LOCALITY: Described from plants cultivated at Madrid, grown from seeds 
said to have come from near the City of Mexico. 
RANGE: Southern Mexico.

Mexico: Orizaba, Botteri 294. Environs de Puevia, October 10, 1909, Nicolas, 
The plant is not uncommon in cultivation, having been introduced into Europe 
as early as 1787. Most of the seedsmen of the United States offer the seeds. A 
form with variegated leaves is known, this being the one illustrated in the Flore 
des Serres. 
This species is readily distinguished from all the others by the very broad, 
rounded calyx lobes which are united nearly to the middle. According to Brand’ 
it has escaped from cultivation in Brazil.
