Notes from Colorado — The lateral canons of the Arkansas Canon 

 between Canon City and Spike Buck Canon, have generally no run- 

 ning water in them. Where they come down into the main canon is 

 a mass of boulders, rocks and sand spreading fan-like in all directions. 

 This "wash" at the mouths of the canons, three to five hundred feet 

 from the river, is irom ten to eighty feet deep. Upon these "washes" 

 bushy trees of Juniperus occidentalis that are more than a hundred 

 years old olten grow, and Opuntia arhorescens as much older than 

 twenty as years it has missed forming anew joint, with old bushes of 

 Bigelovia and many other species of shrubby jDlants. Two dead trees 

 of Finns ponderosa, one large and one medium size apparently grew 

 upon one of these wasiies, but a railway cut uncovering their buried 

 trunks showed that since they had attained their present size, a "wa- 

 ter spout" bringing rocks and sand down from the mountains, had 

 formed a new surface about the trees fifteen feet above the old one. 

 Along the base of the mountains on the plains it is not uncommon to 

 lind old Cottonwood stumps, rotted away, leaving a hole eight or ten 

 j'eet deep down into the soil which has been wsished about them, but 

 the pines, growing in rocky localities can not often be subjected to 

 such catastrophes. — T. S. Brandegee, 



Regular flower in Pedicularis Canadensls. — On May 2d, 1877, I 

 collected near this place a specimen of this plant, which I have care- 

 fully jireserved in the Herbarium of Purdue University, having a 

 strictly regular flower growing from the apex of one of the spicate 

 racemes. The position of the flower as well as the perfect regularity 

 of the corolla, attracted my attention and I carefully preserved it and 

 in a note pinned upon the sheet on which it was fastened is the fol- 

 lowing description wliich I copy : 



The flower is salver form in shape, the tube spreading abruptly 

 above, with a regular border of six lobes each a full line in length. 

 The lobes turn back and face outward, the edges being rolled for two 

 thirds of the length of the lobes, giving them the appearance of being 

 acute. At each sinus between the corolla lobes and just within the 

 border, was a gibbous protubeiance whose blunt point extended a 

 very little beyond the base of the sinus. The calj^x was somewhat 

 irregularly four-lobed, one lobe having a tooth in its margin. The 

 calyx was also split down further on one side than on the other, and
