SOLANACEAE 



Tax. note. — Collections from the southwestern Colorado Desert (Mountain Palm Spr., e. 

 San Diego Co., Hitchcock; Valleeito, T. Brandegee) and from Arizona (Quartzite, Kearney 4' 

 Peebles 10,221), exhibit the calyx in anthesis % to % cleft to the base into linear lobes. In ma- 

 terial from the type locality, on the mesa north of San Bernardino, Parish 795, the calyx is cleft 

 half-way (or slightly less) into ovate lobes. There had been only a single shrub at the type 

 locality, says Parish, and it was long since destroyed.

4. L. brevipes Benth. Thorny shrub, 3 to 8 feet high, with very divaricate 

 branches; herbage minutely viscid-puberulent or subglabrous; leaf -blades oblance- 



olate or spatulate, thick but plane, 2 to 6 

 (or 12) lines long, shortly and indefinitely 

 petioled ; calyx about half the length of the 

 corolla, its lobes oblong or linear, i/^ to as 

 long as the tube; corolla pale blue (fading 

 dull white promptly), funnelform, 4 to 6 

 lines long, its limb 3 to 5 lines wide, its lobes 

 V2 to % as long as the tube ; stamens a little 

 exserted; berry red, globose, 2 to 3 lines 

 broad.

Var. hassei C. L. Hitchc. Stems mostly un- 

 armed ; calyx-lobes 1 to 3 times as long as the tube. — 

 Santa Catalina Isl. 



Field note. — In 1899 Blanche Trask made record (Erythea, 7:140) of an individual of var. 

 hassei at Avalon as follows: It "forms an impenetrable arbor-like network, about one hundred 

 feet in circumference and twenty-five feet in height. Dr. H. E. Hasse says it has grown rapidly, 

 since he first noted it, over ten years ago. Its pale lavender flowers and small red berries are 

 always seen on its virgate branches. The largest branches are six inches in diameter." This 

 gigantic bush has since been destroyed by "the march of improvements."

5. L. torreyi Gray. Squaw Thorn. (Fig. 449.) Roughish erect shrub with 

 divaricate flexuous branchlets, often sparingly thorny, 4 to 8 feet high; herbage 

 mostly glabrous; leaf -blades linear-oblanceolate or oblong, V2 to l^/i inches long, 

 mostly narrowed below to a short petiole-like base ; flowers mostly 3 to 7 in a fascicle; 

 calyx-teeth minute, puberulent; corolla lavender-purple, tubular-clavate with 

 spreading limb, 5 to 6 lines long, the limb 2V2 to 31/2 lines broad, its rotately spread- 

 ing lobes with a well-defined, densely ciliate or tomentulose margin ; berry bright 

 red, globose, 3 lines broad. 



Along washes and stream "bottoms," 150 to 2000 feet : eastern Mohave Desert ; 

 Colorado Desert. East to Texas, south to Mexico. Mar. 



Field note. — In some localities, as in the Colorado Biver "bottoms" and in the washes about 

 Barstow, this shrub occurs in considerable abundance. In "good years" there may be "five crops" 

 of the berries which are harvested by women of the native tribes. A basket is hung over the back 

 and the red berries, crowded thickly on the long branches, are gathered and thrown over the left
