VOL. 5] New Species of Mexican Plants. 257 
This Maurandia is near MV. erubescens, differing in being more 
glabrous and having flowers much smaller, corollas half as wide 
and but slightly ampliated. The peduncles are usually longer 
than the leaves, which often have entire margins. Collected at 
San Luis, Puebla, growing among rocks in the mountains. No. 
2567. 
Pinguicula scopulorum, Glabra vel pilosiuscula; foliis rotun- 
dato-ovatis, obtusis vel acutis, 2-3 cm. longis; 1.5 cm. latis; 
scapis 8 cm. longis; corolla 1 cm. longa, lobis fere zequalibus 
integris, 3-4 mm. longis, purpurascentibus, tubo flavo; calcare 
circa 3 mm. longo, flavo, obtuso. 
This plant differs from P. Uilacina as described in several 
particulars, but chiefly in not having black-punctate leaves. 
Collected at Zacuapan on moist rocks. 
Randia megacarpa. Frutex 2 m. altus cortice cinereo; ramis 
brevibus ad apices spinas 4—nas 12 mm. longas gerentibus: foliis 
obovatis, obtusis vel acuminatis, 2-3 cm. longis, 1-1.5 cm. latis, 
basi cuneatis, fasciculatis, utrinque tomentosis: bacca sessili 
globosa, 3 cm. in diametro, fere glabra. Flores ignoti. 
This probably is the same plant as that of the Xantus collection 
mentioned by Dr. Gray as Randia armata DC.? It is known as 
“‘papache”’ by the people of the country, a name applied also to 2. 
Thurberi and to Genipa echinocarpa in Sinaloa. R. obcordata is 
sometimes called ‘‘ pimiento”’ in Baja California. Inthe mature 
fruit the aglutinated mass of seeds is free and can be rattled 
about, nothing of the placentas remaining. A bush in cultiva- 
tion at San Diego, Cal., although luxuriant, has not blossomed, 
and until flowers have been examined, there must remain a 
slight doubt concerning the genus. The type was collected at 
Comondu, Baja California, Feb. 2, 1889, by T. S. Brandegee.
