GILIA FAMILY 221 



spotted or purple-arched or -patterned ; lower lip 2-lobed, its lobes shorter than the 

 upper ones, divergent, without color markings or sometimes purple-dotted toward 

 base, the sinus more deeply parted than the sinuses between the lips; or corolla 

 sometimes regular; corolla-lobes linear to oblanceolate, acute; stamens strongly 

 declined, these and the style exserted; capsule ovate, 3-sided, II/2 to 2 lines long, 

 the cells 2 to 6-seeded.

Flower variation. — The corolla of Langloisia sehottii is variable in color, ranging from pink 

 to sky-blue or vphite or yellow. Sometimes the corolla is regular but most frequently it is bilabiate 

 with 3 lobes in the upper lip and 2 in the lower. The 3 upper lobes are often embellished with a 

 red or pink or purple color pattern, such as one arch or two arches side by side beneath a White 

 splotch, or are provided with quadrate brownish markings. The 2 lower lobes are smaller and 

 usually unmarked, exhibiting no color pattern, or if the lower lip consists of one lobe medianly 

 placed, then the upper lip consists of 4 lobes. In such case the fourth lobe of the upper lip does 

 not usually exhibit the pattern of arches or other color markings characteristic of the other 3 lobes 

 or not so distinctly, or sometimes all four have the same pattern. 



Field note on Langloisia sehottii and L. matthewsii in cast-central Mohave Desert. — "Lang- 

 loisia sehottii, much less common than L. matthewsii, is a small plant, usually less than 2 inches 

 high, sometimes less than 1 inch. When found growing with L. matthewsii, it blooms first. It has 

 smaller, more delicate flowers than L. matthewsii. The corolla is pale pink with purple-streaked 

 throat, the lobes much shorter than the tube (% to % as long), the upper lip with 2 lobes, the lower 

 with 3 lobes, these lobes purple-spotted but not in the elaborate pattern of L. matthewsii. Lan- 

 gloisia matthewsii, on the other hand, is very common over wide-spread areas, the plants 2 to 6 

 inches high and often twice as broad. The corolla, % to % inch long, varies from pale to deep 

 pink or sometimes it is light salmon yellow ; the lobes equal the tube or they are % as long. The 

 upper corolla-lip is 3-lobed, the lower with 2 spreading lobes, or sometimes with 1 median lobe 

 below and 4 lobes above. The upper lobes are elaborately patterned vrith an arched design of 

 purple dots above a double oblong area. The plants vntb yellow flowers are, it is certain, merely 

 a color variation, since they are identical with the pink ones in every other way. The two color 

 forms of this species are often found growing together." — Mary Beal, in Jepson Corr. 45:41-

Langloisia flaviflora Dav., Bull. S. Cal. Acad. 21:39 (1922), type loc. Willow Sprs., s. base 

 Tehachapi Mts., Davidson 3506. This is based on the characters of yellow corollas and short 

 styles (equaling the calyx), which, if constantly associated might be warrant for a valid species. 

 Yellow-flowered plants growing at Box S Sprs., southern Mohave Desert, have, however, styles 

 exceeding the calyx. 



4. L. matthewsii Greene. Main axis very short, erect, 1 to 1% inches high, 

 bearing many horizontal or divaricate branches, forming a low plant 1 inch to I14 

 feet broad ; branches sparsely leafy or naked and peduncle-like, simple or branched 

 above, ending in dense or head-like clusters of flowers, the heads leaf j'-braeteate ; 

 herbage thinly villous; epidermis of the stems white; leaves linear or spatula te, i/t 

 to IVi inches long, regularly and shallowly pinnatifld, the lobes spine-tipped or 

 replaced by white bristles, the bristles often recurving ; bracts linear, margined with 

 long bristles; calyx about 1/2 to 3/^ as long as corolla-tube, divided nearly to base
