away. Its fruiting season begins here probablj^ early in June. Adiantmn pedatum, 

 L., also appears in fruit early in July and continues on into the fall. It is quite 

 common on the shaded parts of the river hills and at a heijrht of about 17t to 200 

 feet. We have also observed its occurrence in some of the rich thickets. This ap- 

 parent growth within a certain range of height is quite marked here in at least 

 another species, Felhm atropurpurca, Link., which occurs all along the river cliifs 

 and with a few straggling exceptions which are the result of the disintegration of 

 the upper rocks, is confined to a range on the topmost rocks little, if at all, exceed- 

 ing 30 feet in vertical height. Of the genus Aspleniiim we will simply mention the 

 species A. aiiijustifollum, Mx.. A. tliehipteroides, Mx., and A. Filix-fannina, Bernh., 

 which were mentioned at some length in a previous number of the Bulletin. 

 Camptosorus rhisophi/llus, Link., is abundant upon most of our shaded and moss- 

 covered rocks, both in the neighborhood of the river and along the banks of our 

 lararer creeks. Its luxuriance is a marked feature of the bi-oken rocks in the val- 

 leys running into the Ohio. We have noticed some striking variations in the char- 

 acter of the basal lobes of the frond, in one of which these lobes are prolonged out 

 from the rhachis on each side from an inch to an inch and a half into a long linear 

 tip. Phegopteris hexagonoptera. Fee, appears sparingly, during late summer and 

 fall, in the richer and rolling woodlands and generally along the banks of small 

 streams. — (To be continued in May number.) 



Some alpine plants found on Mt. Lincoln, Colorado. — A botanist who has 

 never ascended a mountain peak in midsummer and seen its wonderfully rich and 

 varied flora, has a treat before him which others may well envy. A wortl descrip- 

 tion falls so far short of the reality that it does not seem to convey any correct idea 

 of the beauty and brilliancy of alpine flowers. They are found growing in pro- 

 fusion on most mountain heights, covering with beauty the grassy slopes on the 

 rockj' declivities from timber-line to the very summit. Xothing on the plains can 

 approach in rich and delicate beauty these children of the mountain tops, chilled 

 every night to freezing and drawing their nourishment from the just melted snow. 

 The writer was never more delighted with an alpine flora than when he made an 

 ascent of Mt. Lincoln, in Colorado, a peak considerably over 14,000 feet in height. 

 The ascent was made on July 9th, 1873, a highly favorable time to see mountain 

 plants in all their glory. Late the evening before we had encamped at timberline, 

 which is, in Colorado, from 11,000 to 12,000 feet elevation. This timberline is de- 

 termined by the lying of the snow in spring. Of course the highest tree growth is 

 evergreens, which are curiously knotted and twisted by the weight of the winter 

 snow. Early we commenced the climb and every step in advance brought us to 

 new beauties, and long before the summit was reached our portfolios were gi'oan- 

 ing with treasures which neither love nor money nor fatigue could have induced 

 us to throw awa}^ Time or space will not permit me to enumerate half the plants 

 I secured that dav, but I will mention a few of the most prominent. 



We had not gone ten yards from camp when we found ourselves amongst thick 

 clumps of Pentstemon glaucus, Grab., with its dense clusters of verj^ dark i^urple 

 flowers. Near by were growing the two Poli/gonacece always found in the Kocky 

 Mountains, Pohigonuin Bistorta, L., var. ohlanijifi ilium, Meis., bearing its large dense 

 spike of white flowers, and Oxgria digijna, Campd. We also secured three or four 

 specimens of the delicate little AdoxAi MnschateUina. L., exhaling its faint musky 

 odor. All along the slopes were growing the blue Mevtcnsia aljiina, Don., and tlie 

 darker blue Polemonium confertum, Gr. with its crowded and musk-scented clusters 

 of flowers. The Anemones were out in profusion of numbers and species, flashing 

 at us everywhere with their large and various colored flowers. There were Am^.- 

 rnone patens, L., var. Nuttalliana, Gr., A. pnni^ffoni, Mx., A. multifida, DC, bj^ far 

 the most common and brilliant, and the rarer A. norcissiftura. L.. with its solitary 

 white flower. Thnlictrum Fendleri, Eng., was also growing in great profusion 

 along with Ranunculus udoneux, Gr., the most sliowj' species of the genus. Its
