THE AMERICAN BOTANIST 135 



a member of the Rose family, having small linear fascicled 

 leaves and small white flowers in rather large panicled 

 racemes; wild buckwheat {Briogoniim fasciciilatum foliolo- 

 sum), which also has small fascicled leaves and whitish flowers 

 in terminal cymose umbels; scrub oak (Qucrcits duniosa) 

 and other shrubby growth. The canyon floor is shaded by 

 alder (Alnus rhomhifolia), live oak {Quercus agrifolia), 

 sycamore {Platanus racemosa) and occasionally other trees. 

 The flowers that claimed our notice as we passed along were 

 Godetia Dudley ana, now in full flower and making a fine show 

 of pink flecked with purple; wild Canterbury bells {Phacelia 

 W hitlavia) , with their deep blue bells; large-flowered phacelia 

 {P. grandiflora) with its white to lavender rotate corollas; 

 Antirrhinum glandulosum, with its tall spikes of rose colored 

 flowers; Gilia Grinnelli, a slender plant with loosely few- 

 flowered branches, the corollas somewhat lilac in color with 

 a purple tube; sticky monkey flower (Diplacits longiflorus) 

 with tubular-funnel form flowers, the upper lip two-lobed and 

 the lower three-lobed more or less crenately toothed; and 

 the tree poppy (Dendroniecon rigiduni). Occasionally we 

 saw Lilinm Humholtii but the full glory of this magnificent 

 lily is only to be found at higher elevations and especijdly 

 where it is more unusual for excursionists to come. The 

 reason for this is obvious. It grows in loose rich soil, never 

 in bogs or wet places. The stems are often more than four 

 feet high and sometimes bear forty to fifty flowers, the seg- 

 ments of which are two or more inches long strongly revolute 

 and reflexed, reddish-orange with maroon spots. 



The upper part of the Arroyo Seco runs approximately 

 east and west and meets the upper end of the West Fork of 

 the San Gabriel at a "saddle" almost directly back of San 

 Gabriel Peak. The chief trees of this portion of the Arroyo 

 are canyon oak {Quercus chry sole pis), laurel bay {Umbel-
