EDW. L. GREENE. i Catholic University of America, ^ Washington, D. C., 23 Jan., 1901. 425037 NARRATIVE. By F. S. EARLE. In planning a botanical collecting trip to Southwestern Colorado our objects were first, to secure sets of plants rep- resentative of the flora of this interesting region ; and, second, to study in the field the effect of altitude and exposure on the variability and the distribution of species. It was at first hoped that we might be able to examine some- what critically the La Plata Mountains in the extreme South- western part of the State, and also considerable portions of the larger neighboring range of the San Juan. Lack of time prevented carrying out the latter plan, the work being confined exclusively to the La Plata Range, and the neighboring lower levels. The region proved ad- mirably adapted to the purposes of the expedition. The Range is isolated, and though small in area is of consider- able altitude, the central peak, Mt. Hesperus, holding its rugged snow-streaked crest at the height of 13,300 feet. As seen from the west this mountain presents a peculiar and fantastic appearance. The portion above timber line is a regularly outlined rock pyramid formed of nearly horizontal strata of various colors giving a curious banded effect ; while numerous gulches filled with snow mark it with vertical lines of white. Mt. Hesperus is flanked and supported on the North by Shark's Tooth, a pinnacle of rock well deserv- ing its name ; on the South by the jagged double peak of Mt. Moss, or Mt. Hayden as it is locally called, and on the East by Snowstorm Peak, which justified its cognomen dur- ing our stay in its neighborhood by covering itself with a fresh coat of white in the middle of July. None of these 2 PLANTS BAKERIAN^E. outlying peaks rival the central mass of Mt. Hesperus, but all reach nearly or quite 13,000 feet, and their sheltered gulches hold abundant snow far into the summer to feed the mountain brooks, and furnish moisture for the luxuri- ant alpine vegetation that springs up like magic as the snow line retreats. From the basins between these peaks arise many streams. The La Plata River rises to the east- ward of Hesperus and flows nearly due South ; East, Middle, and West Mancos creeks flow from its western flanks, all uniting above the town of the same name to form the Mancos River, which flows in a southwesterly direction. Bear Creek rising North of Hesperus, between that peak and Shark's Tooth, flows to the northwestward, while the drainage from the eastern side of Shark's Tooth and Snowstorm Peak and is tributary to the Las Animas. Two of our party reached the little town of Mancos on the Rio Grande Southern railway on Tuesday, June 21, 1898, and went into camp near the river to await the com- ing of the third member who had been detained at his home in Mississippi by a suddenly-imposed yellow fever quarantine. The valley at Mancos is from one to two miles wide. For- merly a sage plain, it is now, thanks to irrigation, mostly covered with green wheat and alfalfa fields. Owing to its elevation. 7,000 feet, corn and the more tender vegetables can not be grown on the Mancos. To the North and East the valley is bounded by the foot hills and lower ridges of the La Plata Range, the snow-streaked top of Hesperus being plainly visible. The hills bounding the valley to the South are strikingly different from these in conforma- tion, being flat-topped with precipitous sides, evidently belonging to the great mesa formation of the Southwest. The steep northern slopes of these mesas facing the valley NARRATIVE. 3 are covered by a dense growth of chaparral, giving them in the distance a deep blue or almost black effect. This cha- parral consists largely of scrub oak Quercus undulata inter- spersed or sometimes almost replaced by clumps of Ame- lanchier, Peraphyllum, Rhus, Fendlera, and Cercocar- pus. The summits of the lower foot hills on either side of the valley support a scattered growth of nut pine and red cedar, Pinus edulis and Juniperus monosperma. Looking west- ward the eye wanders over great stretches of undulating sage plains and piiion-covered ridges to the Blue Mountains of Utah a hundred miles away. Southwestward the view is limited by the less elevated Ute Mountain Range, lying distant some thirty miles. The five days of a necessary detention at Mancos were devoted to the flora of the valley ; and ' these proved quite as instructive as any equal portion of time spent at higher altitudes. Three well-defined floral belts were reached from this riverside camp. First, the flood plain of the Mancos, a narrow bottom, varying from a few yards to a quarter of a mile in width. Some parts of it are grassy and meadow- like ; others occupied by swampy thicket. The largest trees are those of the narrow-leaved poplar, Populus angustifolia ; and this was the only member of its genus seen here, except the aspen. The buffalo berry, Lepargyrea argentea, conspicuous by its silver-gray foliage, is abundant, forming large clumps, and reaching the height of fifteen and even twenty feet. The thickets are composed of various willows, interspersed with some choke-cherry trees, Cerasus demised, and dogwoods, Cornus stolonifera ; these supplemented by dense masses of Distegia involucrata reminding one of the hedges of so-called "buckbrush," Cephalanthus, bordering the banks of swampy lakes in Mississippi River bottoms. At this elevation the Distegia (the Lonicera involucrata of 4 PLANTS BAKERIASLE. some authors) attains the height of eight or ten feet; but up near the timber-line it is a dwarf of sometimes not more than one or two feet. The more conspicuous herbaceous plants of these thickets are Mertensia ciliata, Geranium Rich- ardsonii, a new species of buttercup, Ranunculus Earlei (Greene), and Polemonlum filicinum, a species originally from southern New Mexico, and which here it may be assumed, reaches its northern limit of distribution. Among such as these were also gathered a few herbaceous plants, notably Carex aurea and Collomia lanceolata, and several more, which are more properly subalpine and alpine. And as we after- wards grew familiar with the whole region, including the higher elevations about the headwaters of this stream less than twenty miles away, the wonder constantly grew, not that only a few alpine or subalpine plants should occur in the valley below, but that so few of these species had been able to adapt themselves to the condition of the lower levels even where the cool thickets furnished such excellent shade with abundant moisture, and the rapidly flowing stream offered such abundant facilities for the downward distribution of seeds. As a rule the Mancos specimens of species having a considerable altitudinal distribution were taller and more slender than those subsequently taken in mountain mea- dows ; which variation seems attributable partly, at least, to their having grown in the shade. But in other cases, such as the Collomia and Carex aureo,, the low elevation seemed to have had the opposite effect of dwarfing the plants ; speci- mens from about Mancos being much smaller than those taken at elevations greater by a thousand feet. Separated from the flood-plain by a steep bank five to fif- teen or even twenty feet high, and constituting a more elevated secondary bottom, the sage plain stretches away for a mile or more on either side of the valley to the foot- NARRATIVE. 5 hills. This tract, as I have said, has in part been reclaimed and brought under cultivation. Originally it was covered with low-growing gray-green chenopodiaceous and composite shrubs, such as constitute what is commonly called sage brush. Those portions not under cultivation exhibit these growths, intermixed with clumps of bushy Amelanchier and Peraphyllum representing the family of the Pomacese; and it also supports a peculiar and most interesting herbaceous flora, made up of Lupinus argenteus and other lupines, numerous species of Astragalus and other papilionaceas, several Pentstemons and Castilleias, Allium acuminatum and Calochortus Gunnisonii representing the lily family. The pinon belt occupies the low foothills from 100 to 400 or 500 feet above the valley. Here Pinus edulis and Juni- perus monosperma combine in not unequal proportions to form a low scraggy woodland growth. Neither species often exceeds twenty feet in height, and each is frequently adorned by its own species of parasitic Razoumoffskia and Phoradmdron. Herbage is scanty in this belt, and the her- baceous species quite characteristic, like Lescuriella Palmeri, Pentstemon linarioides, Astragalus scopulorum and Picradenia Richardsonii. Our belated Mississippian, Professor Tracy, arrived in the morning of June 26 and we started at once for the western flank of Mi Hesperus, our wagon piled high with boxes of paper, presses, bundles of driers and camp equipage. Our plan was to make a somewhat permanent camp as near timber line as we could go with a wagon, and then to take time to thoroughly explore the country both above and below. Our road started due north from Mancos but soon bore northeast and followed up a rather narrow ridge or divide between the deep rocky canon of the West Mancos on the right, and Chicken Creek, a smaller tributary of the 6 PLANTS BAKERIAN^E. Mancos, on the left. About four miles from town, and at an elevation of some 7,500 feet, we left the pifions and the chaparral-covered hillsides through which we had been traveling, and came suddenly into magnificent open pine woods. Our driver told us that the lumbermen distin- guished two kinds of pine, but all seemed to be Pinus sco- pulorum the difference in the timber being probably due to differences in the age and condition of the trees. Many of the pines are of large size and the ground between them, while mostly clear of brushwood, yields a sufficient growth of grass and herbage to give it an attractive park-like effect. Though the collecting in this lower part of the pine belt was not specially interesting, it furnished a few charac- teristic plants, such as Lotus Wrightii and Lithospermum multiflorum. Advancing toward higher ground, the winding road brought us to an elevation of about 9,000 feet, where the pines give place to aspen thickets. At this point we ob- tained our first impression of the riches of vegetation belonging to the higher mountains; for the aspen thickets of limited extent were found to alternate with considerable stretches of native meadow brilliant with a great diversity of flowers blooming among the abundant grasses. Fields of the large sunflower-like JFye£/mi Arizonica, clumps of purple lupine bordering these, red Castilleias and white Polygonum bistortoides, Potentillas of several sorts along with other things as show}' combined to form a beautiful and most inviting botanical landscape. Still continuing the gradual ascent, spruces (Picea Engel- mannii) began to intersperse themselves in groups among the aspen clumps, becoming gradually more and more pre- ponderant, until finally the aspens cease altogether at 11.000 eet, where the spruces thenceforward hold undisputed sway NARRATIVE. 7 up to the timber-line which, in this latitude, is at about 11,500 feet. Having made a late start, on this first day of the ascent, we covered only about fifteen miles, camping for the night near the head of Chicken Creek. A little beyond this point our road descended abruptly into the West Mancos Canon, thence following that stream up to Jackson's stamp mill, at the very base of Mt. Hesperus. The difficulty of getting our heavy outfit back out of this deep canon seemed so great that we decided to keep on up the ridge, following some old cattle and pack trails as far as it should prove practicable to take the wagon. We succeeded in getting three or four miles further, and made our second camp on the headwaters of a little tributary of the West Mancos locally known as Bob Creek. We had reached an elevation of 10,500 feet and were about two and a half miles due west of the main peak of Mt. Hesperus, but with the deep and rugged valley of Slide Rock Creek lying between. The laborious climb out of this valley with a heavy load of plants, after a day's collecting on Hesperus convinced us that we had made a mistake in not taking the lower road and so pitching our camp in the canon, when the home- ward trip would always have been down hill. The region above timber was reached in three different places from this Bob Creek camp, on the southwest face of the ridge between West Mancos and Slide Rock Creeks, which constitutes the westernmost spur of Mt. Hesperus, on the north face of the same ridge farther east near the head of Slide Rock Creek, and on the Bear Creek divide north- east of camp. In all these places the ground was rather dry and exposed. Many interesting plants were taken, but the full glory of the alpine vegetation was not seen till we 8 PLANTS BAKERIAN.E. reached the moister basins at the head of the La Plata River on the eastern side of the range. One of the most interesting features of this western flank of the range was the great reaches of verdant mountain meadow stretching away in every direction between the scattered clumps of spruces and aspens. The grass, con- sisting largely of Poas and Festucas, was exceedingly luxuriant and was everywhere sprinkled or crowded by showy species of Mertensia, Polemonium, Valerianella, Frasera, Veratrum, Aconitum, Delphinium and numberless other smaller flowering plants. The morning of July 6 found us breaking camp and starting on the return trip to Mancos. The season was now at its height, and it was marvelous to see how rapidly vege- tation was developing at these high altitudes. Had time permitted we should gladly have lingered longer at this camp, for each day brought new species into bloom, and it seemed to our regretful eyes that we were leaving more still undeveloped species behind us than we had found in con- dition to collect. The trip back to Mancos occupied two days, as much time was consumed in collecting on the way the things that had opened during our brief absence. A further stop of two days in Mancos enabled us to pack and ship the dried plants that had accumulated, and to take a short side trip over the sage plains to the south westward along the road toward Cortez, in the direction of the Ute Moun- tain. This day's collecting proved to be the richest in the number of specimens taken and in the number of new species of flowering plants discovered of any on the entire trip, thus showing that in planning future work in this region the lower levels should receive careful attention. The afternoon of July 9 found us again under way for a trip up the La Plata Valley on the east side of Mt. NARRATIVE. 9 Hesperus. Our route lay over some low divides through a rather uninteresting country, part of the time in oak chaparral, and at times getting up into the open pine belt. During the afternoon of July 10 we passed Dix P. O. and reached the old mining camp of Parrott City at the foot of the mountains, just at the entrance to the canon of the La Plata River. Continuing a few miles further, we made camp in the bottom of the canon about two miles south of La Plata City. This was one of the richest spots visited. The bottom of the valley is only a few hundred yards wide, and it is walled in on either side by the pre- cipitous slopes of the mountains. It is very moist, and is filled with a luxuriant tangle of vegetation. Rubus Nutkanus here grows to perfection, and the ground is fairly carpeted with the showy Erigeron coulteri and Penstemon glaucus stenosepalus. The gravel banks in the stream also furnished conspicuous and abundant species, including Epilobium latifolium and Senecio atratus. The elevation here was about 9,000 feet. On July 12 we again moved camp going toward the head of the valley. Above the town of La Plata the canon grows much narrower and the grade is much steeper. The road is soon forced to leave the stream and is cut into the hillside. For a considerable distance no suitable place for a carnp could be found, but finally just below the mouth of Basin Creek, at about 10,000 feet elevation, a projecting ledge of rock gave us just room to put up the tent and get the wagon out of the road. Stakes being out of the question tent ropes were made fast to boulders, and our quarters, though re- stricted, proved sufficiently comfortable. Wagon roads have been constructed several miles farther to reach various stamp mills, but they were so rough and steep that we did not attempt to take our heavy outfit beyond this 10 PLANTS BAKERIAN.E. point but made daily trips above timber line in various directions. The basins of the small streams far above timber line were here all veritable alpine gardens well stocked with Mertensias, Polemoniums, Trifoliums, Erigerons, Castilleias and many other showy alpine genera. Even the most rugged slopes exhibited a great diversity of species ; for every nook and crevice among the rocks where any soil had found a lodgment was filled with plants. On the very summit of Ml Hayden at 13,000 feet we gathered excel- lent specimens of Trifolium nanum, Chionophila Jamesii, Ligusticum Eastwoodiae and Pentstemon Harbourii. It is to be noted that about three-fourths of the plants collected here were of species not represented at any of the lower altitudes. It was with much regret that on July 16 we took leave of this interesting locality and made our way to Durango. Each little sheltered slope and basin that we visited fur- nished some plant not seen elsewhere, and, had time per- mitted a thorough exploration of the region our list of species would have received many additions. Furthermore, the flowering season had not yet reached its fullness. Very many species were not yet beginning to bloom, and it was manifest that a month's sojourn would have enabled us to nearly double our collections. This Alpine research was disappointing in respect to only two groups of plants. Of ferns we took but two species, Cystopteris fragilis and Oryptogramme acrostichoides ; and the number of lichens was much smaller than had been antici- pated. The bare rocks supported a fair number of crusta- ceous species, which, owing to the early loss of our chisel, we were unable to collect ; and terrestrial and arboreal species were very scarce. NARRATIVE. 11 Durango is a thriving town located in the valley of the Las Animas river at an elevation of 6,500 feet. South of the town the hills rise 1,000 or 1,500 feet higher. They are mostly composed of beds of shale with a few coal-bearing strata and so give but few plants of interest during the hot midsummer months, even along the narrow ravines and arroyas. The Grindelias, Mentzelias and Eriogonums found within the city limits proved fully as interesting as the plants of these nearby hills. In some places they sup- port a considerable growth of Juniperus monosperma with scattered trees of pinon. Near the eastern edge of the town one small hill was noticed that had been covered by a rather dense growth of this juniper, but now only a few of the trees were living, the others having apparently been killed by Gymnosporangium speciosum Peck, which had left the swollen and distorted trunks marked with its peculiar plicate tumors. North of town toward Trimble Springs the Animas valley is somewhat broader, though bounded on each side by pre- cipitous mountain walls which rise from 2,000 to 2,500 feet above the stream. Every acre of irrigable land is in a high state of cultivation, hay or green fields and orchards filling all the valley from Durango to where the Hermosa River joins the Animas. Here we noted similar willows to those found at Mancos and at the base of the cliffs were box elders and Ribes cereum. Through the kindness of Col. Thomas Hamor, of Durango, we were enabled to make a somewhat hasty trip to Colum- bine, twenty-five miles north of Durango, on the old Silverton trail, and only a few miles to the eastward of our Upper La Plata camp. The place is near the head of the valley, and Hamor's Lake, a picturesquely beautiful sheet of water, is one of the sources of the Las Animas river. The lake 12 PLANTS BAKERIAN.E. seems to have been formed by the sudden closing in of the canon wall so that though not large it is of great depth. It is as clear as crystal and even after our visit it still contains some magnificent trout. The elevation here is about 9,000 feet and the hills and wet meadows near the lake yielded a greater number of species than any other equal area that we visited. In the water of the lake itself was an abun- dance of Chara Hippuris and Potamogeton while on its borders were Thalictrum alpinum,Gentiana heterosepala,Swertia scopulina, Agastache urticsefolia, Lilium montanum and many other species not taken elsewhere. Mr. Tracy, who was the last to arrive, remained in the neighborhood of Durango until July 28. Messrs. Earle and Baker departed on the 18th and 19th respectively, making about an even month in the field for each of the three members of the expedition. Perhaps the most striking impression gained by the trip, aside from that produced by the abundance and beauty of the high alpine flora, is that of the distinctness with which the different altitudinal floral zones are marked out and limited. It is true a few species were found all the way from the Mancos River bottoms at 7,000 feet to timber line at 11,500 feet, but these instances are rare. In the great majority of cases each species observed had an altitudinal range of not to exceed 1,000 feet, even with similar con- ditions of soil and moisture. In a general way these life zones seemed to be the same here as in the not far distant San Francisco Mountains of Arizona, where they have been so carefully studied by Dr. Merriam, of the U. S. Biological Survey. We could easilv distinguish the pinon-cedar belt, the pine belt, the aspen-spruce belt and the timber line belt as designated by him, and we found this division a very useful one in the prosecution of our work. NARRATIVE. 13 While we endeavored to make our work as thorough as possible for the very limited region actually explored, we realize fully that it is only a beginning. The number of plants collected serves to illustrate the great floral richness of the region, and our experience suggests that for future work the higher mountains should be visited during the period from July 15 to September 1, when an almost entirely new set of plants would be in bloom; and that work in the lower levels, especially in the canon and mesa region south and west of Mancos is greatly needed earlier in the season, say from May 1 to June 15. It is hoped that at least some of our party may be able to continue the work another season. CATALOGUE. FUNGI. By S. M. TRACY and F. S. Among the more striking features of the fungus flora of the region which the collection represents may be men- tioned the great abundance of the Uredinales and Sphserlales. The Erysibacese would have been abundant later in the season, though only two species were found in condition to collect. Perisporacese were entirely lacking, as were also the Hysteriales, though the latter were persistently sought for everywhere. The Pezizales are represented by only two species. The Helvellales do not appear in the list, but fine specimens of Morchella and Gyromitra were observed in the high spruce woods. The Agaricacese are very scantily rep- resented in the list, but they were really quite abundant in moist locations at the higher altitudes. Lack of time and of facilities for properly drying the specimens prevented collecting them. Among the Sphseriales which constitute nearly a third of all the species collected, and of which con- siderably over one-half proved to be undescribed, the almost entire absence of such common eastern genera as Hypoxylon and Valsa is to be noted, as well as the great abundance of Lopliiostomatacese, a family rarely found by eastern col- lectors. The Dothideales and Hypocreales are each repre- sented by a single species only. It is interesting to note that of the entire collection only the following five species were taken above timber line: Schizonella melogramma, Puccinia acrophila, P. Claytoniatum, P. Pimpinellas and Patinella Crandallii. The smallness of this list is to be accounted for in great part by the fact that our BAKERIAN^, Vol. I. Pages 1-53, Feb. 22, 1901. 9210-2 (15) 16 PLANTS BAKERIAN^E. time above timber line was always limited and that the beauty and abundance of the flowering plants claimed our attention, to the neglect of the Fungi. In the following list the sequence of families is that of Engler & Prantl. In the few cases in which the generic name used by us is another than that employed by Saccardo in the Sylloge Fungorum, the latter is added in parenthesis. PERONOSPORACE.E.

This causes fusiform swellings of the limbs much like those formed by G. clavipes, but the spore-masses are different in shape and of a lighter color, and the spores lack the swollen pedicel characteristic of that species. It is probably new, but our specimens are not in a condition to insure correct diagnosis. 20 PLANTS BAKERIAN.E. GYMNOSPORANGIUM SPECIOSUM Peck? Bot. Gaz. iv. 217. On branches and trunks of Juniperus monosperma, Durango, 6,500 feet, July 20, n. 1079. This forms large fusiform, plicate swellings on the trunks or larger branches, frequently causing the death of the tree. The specimens were too old for positive identification.

We have not seen European specimens. SORDARIACE.E. HYPOCOPRA FIMICOLA (Rob.) Sacc. 1. c. i : 240. On cow dung, Bob Creek, 10,500 feet, July 2, n. 1105. HERPOTRICHIA NIGRA Hartig Hedw. xxvii. 13. On living leaves of Picea Engelmannii, Bear Creek Divide, 11,000 feet, June 29, u. 232. This has not before been reported from America. The asci soon vanish, and at full maturity the ascospores are fuliginous. In our specimens the perithecia often reach 5mm. In other respects it closely agrees with the descrip- tion given by Hartig. It was also observed on Mt. Hes- perus near timber line, but was not seen below 11,000 feet. This was previously collected by C. F. Baker on spruce in northern Colorado, July 13, 1896, at Cameron Pass, 10,000 feet, and distributed by him under the name of Lasiosphseria Coulteri, Peck. It closely resembles that pine-inhabiting species externally, but the spores are entirely different. ROSELLINIA PARASITICA Ell. & Ev. Proc. Phil. Acad. 28 PLANTS BAKERIAN^E. ] 890, p. 227.

Winter, Pilze, ii. 206. On dead bark of Picea Engelmannii, Bear Creek Divide, 11,000 feet, June 29, n. 1082. It has previously been re- ported only on pine bark from Europe. Our specimens agree so closely with published descriptions, especially with that in Winter ii, that we so name them, but we have not seen European specimens. ZIGNOELLA POTENTILL.E n. sp. Perithecia scattered, erumpent becoming superficial, black, depressed globose, roughened, Jmm in diameter; ostiolum conical; asci cylin- drical or fusiform, short stipitate, 8 spored, 4 5-5 Oxl 0-1 2/x; paraphyses filaform, longer than the asci ; ascospores hyaline, oval or elliptical, faintly f -septate, 11-12x4-5^,.

On dead twigs of Symphoricarpus, Bob Creek, 10,500 feet, June 27, n. 173, with Rosellinia parasitica and Strickeria Sym- phoricarpi. The true generic position of this species is somewhat doubtful. Its scanty imperfect stroma suggests that it should be placed in the CucurbitariaceaB rather than in Mellogramma, but the vestiture of the perithecia would exclude it from Gibberidia, as that genus is now denned. Since perithecial hairs are present in the nearly related Gibbera, from which our species is excluded by the spore characters, we prefer to widen the definition of Gibberidia rather than to propose a new genus based only on the pres- ence of perithecial hairs. OTTHIA DISTEGI^E n. sp.
