SOLANACEAE. Nightshade Family. 
Lycium richii A. Gray. F'RUTILLA. 
Species of the genus Lycium, growing as shrubs 1.8 to 2.5 meters high, form an 
important element in the desert flora nearly throughout the Peninsula and on many 
of the islands, but they are not well known, and most of our specimens are still unde- 
termined. The berries are eaten by small desert rodents and by some of the birds. 
At San Felipe Bay the holes of Citellus tereticaudus were numerous under shelter of a 
dense thicket made up almost entirely of Lycium bushes (perhaps D. torreyt), and the 
animals were carrying the ripening berries in their cheek pouches. In these species 
the fruiting season is much prolonged, and it is not unusual to find flowers with fruit 
at all stages of development on the plant at the same time. Specimens referred by 
Brandegee to L. richii were collected in flower and fruit at Comandi, November 7, 
and in fruit along the road between Tres Pachitas and Valle Flojo, December 25. 
Brandegee records L. richit from La Paz. The native name “‘frutilla” is applied 
indiscriminately to several species. 
Solanum hindsianum Benth. 
This species was common in many places along the route from San Francisquito 
southward to San Ignacio and thence eastward to Santa Rosalfa. It is well distrib- 
uted, but more abundant in soft soil along arroyos, growing as a shrub 1.5 to 3 
meters high. Some plants are entirely thornless, while others have a few thorns 
distributed irregularly along the branches. Flowering specimens were collected at 
San Francisquito, September 11, and at Tinaja de San Esteban, 25 miles north of 
San Ignacio, October 5. 
SCROPHULARIACEAE. Figwort Family. 
Diplacus arachnoideus Greene. 
Found rather common on the same hill slopes with Diplacus puniceus in the Upper 
Sonoran Zone along the road from near sea level at Ensenada to about 900 meters near 
Ojos Negros. It grows here as a shrub 1 to 1.5 meters high, with large, handsome 
flowers. A specimen was taken east of Ensenada, May 31. 
Diplacus puniceus Nutt. 
Noted as rather common along with D. arachnoideus and other chaparral on steep 
Upper Sonoran hill slopes from near sea level at Ensenada to about 900 meters near 
Ojos Negros, in San Rafael Valley. It is a handsome shrub growing 0.5 to 1.2 meters 
high. A flowering specimen was collected a few miles east of Ensenada on the road 
to Ojos Negros, May 31. 
Galvesia juncea (Benth.) A. Gray. 
Originally discovered on the voyage of the Sulphur from San Diego to Magdalena 
Bay. Specimens in flower and fruit were obtained by us at the mouth of the San 
Simén River, a few miles south of San Quintin, August 29. The species grows here 
asa shrub 1.8 to 2.5 meters high. Specimens in the U.S. National Herbarium were 
collected on Cedros Island by Lieut. Charles F. Pond, Dr. Edward Palmer, and 
A. W. Anthony, and on San Quintin Bay by Palmer. 
Pentstemon antirrhinoides Benth. 
Of the several species of Pentstemon noted by us this was the largest and most 
conspicuous. Itwasa rather common shrub growing 1 to 1.5 meters high and associated 
with Adenostoma and Arctostaphylos on dry Upper Sonoran hill slopes along our 
route from near sea level at Ensenada to about 1,500 meters near El Pifién on the west- 
ern side of the Sierra del Pinal and San Pedro M4rtir mountains. Flowering speci- 
mens were taken east of Ensenada, May 81, and at El Pifién, J uly 5.
