Erect or spreading herb to 60 cm tall, stems glabrate with scattered, stout, white, often jointed hairs 1-4 mm long, and with minute, appressed or spreading hairs somewhat localized near the nodes. Leaves to 5 cm long, mostly half that This content downloaded from 192.104.39.2 on Tue, 14 May 2013 16:07:58 PMAll use subject to JSTOR Terms and Conditions1973] D'ARCY-FLORA OF PANAMA (Family 170. Solanaceae) 667 size, ovate, sometimes broadly so, apically acuminate, acute or obtuse, basally deltoid, truncate or subcordate, often oblique, the margins entire or sinuate, rarely toothed, glabrate but with minute hairs along the veins and minutely papillate on the lamina; petioles 1-3 cm long; small, 5 mm long, elliptical minor leaves sometimes present. Pedicels to 5 mm long, slender with scattered, long, stout white hairs. Flowers with the calyx 3-4 mm long, 2.5-3 mm broad at the base of the lobes with scattered, stout, long white hairs, especially along the ribs, the lobes to 1.5 mm long, deltoid; corolla mostly with a contrasting eye, 5-7 mm long, pubescent in the tube; anthers blue or violet, 1-1.5 mm long. Fruiting calyx 10-ribbed, the ribs rough or kinky in outline by virtue of enations or teeth pro- duced mostly at the base of the stout hairs, glabrate or pubescent but mostly with some stout white hairs along the calyx ribs, the calyx usually drying reticulate- veined, 10-20 mm long; the berry globose, 6-10 mm across.

Note

No type has been seen for the name used here-the concept is that of Water- fall, 1967), which seems also to be that of Rydberg, Dunal, Nees and other workers. A search for authentic material at Madrid (MA) was unsuccessful. In naming P. lagascae, Roemer and Schultes questioned whether this species might be the same as P. ixocarpa Brot. ex Hornem. or P. inocarpa Brot. In a recent study, Fernandes (Bol. Soc. Brot., ser. 2. 49: 343-367. 1970) discussed typifica- tion of the first of these names, which does not apply to the Panamanian taxon. Few of Brotero's types are extant, and until authentic material of P. inocarpa can be found, the name is best ignored. Physalis lagascae is best recognized by its small leaves, flowers, and fruits and by the teeth or enations of the calyx ribs which give the angles a kinky appearance. The stout white hairs of the calyx and stems is also a useful char- acter. This species is ruderal in habitat and is reported as ephemeral or annual in life span. Although there are few collections from Panama, it may be expected almost anywhere in the country where there is agricultural or urban disturbance. It is well adapted to regions with a seasonal dry period.
