PLATE IV 



YOSEMITE TIGER-LILY, Lilium parvum (Kellogg). 

 Root. Bulbous and fibrous. Stem. Simple, 3-8 

 high. Leaves. Ovate, pale green, thinner than other 

 lilies, in whorls or alternate above. Flowers. Small, 

 f'-i' long, several-flowered, on long, undulating flower- 

 stalks, scarlet and orange, purple-dotted. Perianth. 

 Of oval segments, slightly recurved. Stamens (a). 

 Dark red. Pistil (&). With a head-like stigma. 

 Seeds. Flat. 



The small, gem-like flowers of this beautiful little lily, 

 waving on their long stalks, are particularly attractive. 

 I found them in early August on the upper trails of the 

 Yosemite Valley, growing amid tall grasses and small 

 shrubs. 



ASA GRAY'S LILY, L. Grayi, seems to be rather like the 

 last, with larger flowers and stiffer leaves. It blooms in 

 July and August, on the peaks of Virginia and North 

 Carolina. 



Two genera, not immediately recognisable as lilies, 

 follow : 



GRAPE-HYACINTH, Muscari botryoides, is an herb 

 with long, grass-like leaves from the root, and a short, 

 thick raceme of very small, blue, slightly fragrant flowers. 

 The flowers have a globular, one-pieced perianth, with 

 six small teeth. The clusters much resemble a bunch 

 of grapes, hence the name. 



STARCH GRAPE-HYACINTH, M. racemosum, is similar, 

 with narrower leaves and oblong, starch-scented flowers. 



Both these plants are Europeans escaped from gardens, 

 and bloom in spring. 



STAR-GRASS, COLIC-ROOT, Aletris farinosa, has a 

 rosette of pale, lanceolate leaves at the root and a tall 

 scape topped by a long raceme of small, floury-looking, 

 bell-shaped flowers, erect, roughish, and white, with a six- 

 toothed, one-pieced perianth. This plant grows east of 

 the Mississippi in early summer. A yellow form of it 

 sometimes appears South. 



YELLOW COLIC-ROOT, A. aurea, is similar. It has 

 shorter leaves and shorter yellow flowers. It blooms 

 south from New York in early summer.
