FLOWERING PLANTS AND FERNS OF Alii ZONA 185 



2. LUZULA. Woodrinh 



Plants perennial, leafy stemmed; leaves flat, channeled, or involute; 

 flowers in heads, spikes, or loose cymes, these forming dense or open 

 compound inflorescences; flower bracteolate; stamens 6. 



Plants eaten by livestock and sometimes a fairly important element 

 in mountain pastures. 



Key to the species 



1. Flowers on slender pedicels in a loose, somewhat drooping, many-flowered, 

 cymose panicle; herbage glabrous except for a few long hairs near the 

 throat of the sheath; sepals about 2 mm. long, shorter than or barely equal- 

 ing the capsule 1. L. parviflora. 



1. Flowers crowded, subsessile, in few headlike or spikelike glomerules; herbage 



sparsely villous with long, loose hairs; sepals longer than the capsule (2). 



2. Inflorescence erect; glomerules capitate, borne on elongate branches; leaves 



flat ; sepals about 3 mm. long 2. L. multiflora. 



2. Inflorescence nodding; glomerules short-spicate, sessile or nearly so, forming 

 an interrupted spike or a small, compact panicle of spikes; leaves chan- 

 neled, often involute; sepals about 2 mm. long 3. L. spicata. 



1. Luzula parviflora (Ehrh.) Desv., Jour, de Bot, 1:144. 1808. 



Juncus parviflorus Ehrh., Beitr. 6:139. 1791. 

 Juncoides parviflorum Coville, Contrib. U. S. Natl. Herbarium 

 4:209. 1893. 



San Francisco Peaks (Coconino County), Baldy Peak, White 

 Mountains (Apache County), 10,000 to 11,500 feet, June to Septem- 

 ber. Labrador to Alaska, southward to New York, New Mexico, 

 Arizona, and California ; Eurasia. 



The name Luzula parviflora probably covers a species complex; 

 but until the grcup has received a complete modern revision It seems 

 best to include the forms under this name. 



2. Luzula multiflora (Retz.) Lejeune, Fl. Envir. Spa 169. 1811. 



Juncus campestris y L., Sp. PL ed. 2, 469. 1762.

Rincon and Santa Catalina Mountains (Pima County), about 7,500 

 feet. Throughout temperate North America; Eurasia. 



3. Luzula spicata (L.) DC. and Lam., Fl. Franc. 3:161. 1805. 



Juncus spicatus L., Sp. PL 330. 1753. 



Juncoides spicatum Kuntze, Rev. Gen. PL 725. 1891. 



San Francisco Peaks (Coconino County), 10,000 to 12,000 feet. 

 Greenland to Alaska, New Mexico, northern Arizona, and California; 

 Eurasia. 



17. LILIACEAE. Lily family 



Plants perennial, herbaceous or in a few genera woody; flowers 

 mostly perfect, regular or nearly so, often showy; stamens commonly 

 6; ovary superior or nearly so; stigmas usually 3; fruit a capsule or a 

 berry. 



Some of the handsomest and showiest plants of Arizona, notably 

 the lemon lily (Lilium parryi), the mariposas (Calochortus spp.), 

 and species of Yucca, belong to this family. A substitute for soap is
