Desierto de los Leones

9500-10,350 ft.
July 9, 1944
1. Abies religiosa and Pinus patula. SHRUBS: Arbutus, Arctostaphylos, Ribes, Senecio, Rubus, Salvia, Lonicera pilosa, Smilax (hispida?), Sambucus mex., Symphoricarpus microphyllus. HERBS: Erigeron, Oxalis like purpurea, Monotropa, Hypopitys, Chimophila umbellata,Heuchera, Galium, Fragaria mexicana, Heuchera, Arenaria, Asplenium (Trichomanes parvulus type), Polemonium, Osmorhiza, Coralorhiza, Thalictrum, Myosotis, Adiantum, Arabis of laevigata group, Alchemilla (2 sp.). FUNGI: Lactarius camphoratus and deliciosus?, Geaster, Lycoperdon, Cortinarius (blue), Pluteus cervinus?, Boletus.
Pinus patula probably introduced by the convent. Senecios common and varied, herbaceous to shrubby--one with basal leaves like Solidago glomerata. Fuchsia (shrubby), Salvia of many kinds, common. Little of any calcareous material. Mosses of forest floor mainly Thuidium and Mnium. Miniature Peperomia on wet bluff, Cupressus lusitanica L. on lower slopes, also Pinus montezumae. Pinus also above Abies at 13,000 ft.

We were not below or above the fir forest. Nos. 1 to 86 -- Non-Vascular Cryptogams!
On July 20 and 21 tremendous quantities of Amanita caesarea were offered for sale in the markets of Puebla along with a few Lactarius. A small number were bought for UT Herbarium.

Río de La Magdalena above Contreras

in Distrito Federal beginning at the

2nd Dynamo.

9000 feet


July 23, 1944.
Abies religiosa mainly, a little Cupressus lusitanica. Arbutus (similar to Desierto but less virgin). Lower down (8500 ft.) more oak.
On steep opposite 2nd dynamo — Begonia takes the place of Saxifraga in Tennessee in rock crevices. Here also is the minute Peperomia along with Galium, Cerastium, Tradescantia, Adiantum, Asplenium, a Polypodium resembling P. virginianum. Along the river is Sambucus mexicana, shrubby Eupatorium and Senecio. Phytolacca, Oxalis (white but resembling O. violacea in some ways). Cystopteris fragilis.
Seen but not collected: Crassula, Maguey (lower down—large Bromeliads on trees and cliffs), Arbutus, Quercus (holly-leaved and lanose-leaved).
Fungi seen but not collected: Russula, small ones of Marasmius and Mycena types in mosses on bluff and on logs.
Many of the shrubs common to eastern North America, such as: Philadelphus, Viburnum, Ribes, etc., were found locally on cold, seeping bluffs.
Río de la Magdalena has a gorge, which is at the foot of Mt. Ajusco. Consultation of the best map available leads me to believe that I followed Río de la Magdalena.
*** (Cryptogams, excluding Ferns) stop at # 164. (Start at 87)

Llano Grande above Río Frío

54 Km from Mexico City

In state of Mexico


July 28, 1944.
The broad flat valley (perhaps 500 acres) is overgrazed and free of trees. It has an elevation of 10,350 feet. To the south lies Iztaccihuatl. The slopes immediate to the valley have pine (see specimen) and have been burned in the last year or two. The only evidence of deciduous trees are stump sprouts of alder and willow in the moist sites. Also in the moist sites was an Erygnium (not yet in flower) which looked like E. aquaticum. A red-topped Russula, another Russula wich mimicked a Lactarius of Piperitus group were seen. Also seen were: Lepiota, Hygrophorus (3 sp.), Collybia (of Butyracea type), and other agarics unknown to me. One Psalliota was seen. The pines were covered with lichens (no time for collections) and a few mosses. There wasnftt much suggestion of even the subtropics—no bromeliads—only one Echeveria. Rubus and Ribes were seen without flowers or fruit. A Botrychium frond was seen in the pinewoods.
Cryptogams start at 165 and run to 186.

Pine forest up to no. 44102 (not including). (In every case read Llano for valle.).

July 30, 1944
Above the village of Río Frío upstream toward Volcán Telapón, I started collecting at 9950ft, in a fir forest (some Cupressus and holly-leaved oaks). Pine and Arctostaphylos. Alnus sprouts in wet spots. Highest elevation, 10150 feet.
Fungi noted but not collected: Amanita caesareae, Pholiota, Cortinarius (purplish), Lactarius deliciosa?, and other sp., Amanita verna, Russula, Cantharellus 3 sp. (one like floccosa, one like aurantiacus (see specimen) and one too young to tell), Lentinus (the bluest gills I’ve over seen), Clitocybes, Marasmius, Mycena, etc. Woods full of them.
Here as elsewhere the forest is being depleted 3 ways: charcoal burners, fire and lumbering.
Cryptogam nos. start at 188 and run to 264.

August 6, 1944.
Joined by Mr. C.L. Gilly, Sr., I again scouted up the river (Río Frío) toward Mt. Telapon. More attention was paid to the slopes and particularly to the bluffs towards the east than to the valley floor near the river. An elevation of 10400 ft, was reached. My guess is that the bluffs were of metamorphosed conglomerate (light grayish-pink). Fire at points had even burned the mosses.
Little or no Abies or Cupressus was found on slopes. The largest trees were Pinus. Underneath were holly-leaved oaks. Arctostaphylos common below 10,250 ft. Arbutus above. Ceanothus (small trees) common just below bluffs. Bromeliads on trees on the slopes.
Shrubs recognizable: Salvia, Gaultheria?, Fuchsia.

Herbs not collected: Peromia.

Fungi noted, not collected: ramiform Clavarias, Xylaria, Lactarius peckii but with orange milk, Lentinus (bright blue), Cortinarius, Amanita, Collybia platyphylla, Psathyra or Psatyrella on cow dung, a Lactarius resembling L. camphoratus, but with and involute, pubescent margin, Inocybe, Hygrophorus of the cerasus type, Mycena, Marasmius, Panus, minute fragile white Pleurotus, Russula.
Vasculars retained by Gilly.

Only a small area was covered! All rock was lava with minute crevices to large pockets, 100 or more feet long and often nearly as wide with shallow soil in all places where it could collect. Deep (10 ft.) moist fissures are also present. Frequently the lava overhangs and shades moist ledges below. No trees—only small Schinus molle and semi-shrubby, semi-fleshy Senecio are conspicuous. Cacti (Opuntia and small ferns) are common although not abundant. Pastured rather severely by goats and cows.
Noticed but not in flower or fruit: Agave, Geranium, Grasses (fox-tail et al).

Only fungi seen: 2 same spp. birdfts nests; and one fragile, white gill-form on dung.

Collected all species of ferns that I saw.

La Gavia, the center of and old, large holding of land is situated in a bluff overlooking a small river which probably becomes dry during the dry season. The bluffs looks to be a mixture of volcanic mud, stones and ash. The bluff (less than 100 feet high) is abrupt in spots but more often a steep slope on which has been planted below the buildings Cupressus lusitanicus. Under these trees in a rich black loam. Collections were made between the buildings and the river and across the river in wet spots and a roadside ditch. The elevation of the area is approximately 8800 feet and is relatively a rolling plateau, about northwest on Nevado de Toluca . The river (probably nameless) is a tributary of the Lerma and flows form the mountain. From the car (the driver was in a hurry) I noted what appeared to be large numbers of Psalliota in the roadside pasture as we went from the highway to La Gavia.
August 11, 1944
It is my impression that the mountains and high plateaus were once heavily forested but between agriculture and wood cutters (for charcoal) the forests have been denuded, except in higher and more inaccessible places. Better crop plants need to be developed (plant breeding) in order that more land may revert to forest . Better forest practice is also necessary as it will tend to help solve the water problem and the problem of erosion which is most acute.

Chas. Gilly, Efraím Hernández and I walked from the Obregon Monument to the circular pyramid at Peña Pobre and thence to Tlalpan. We did not the highway until we reached P. P. but crossed the lava field, adding to the collections I had made August 8, 1944. Gilly at present has the vasculars. The lava flow is considered to be 2000 years old (see Edgar Lee Hewitt’s Ancient Life in Mexico and Spinden’s Civilizations of Mexico).

I started at the village and collected the roadside (including the bluff) toward bridge, before reaching the bridge. I dropped into the barranca (canyon) below the bridge. I did not go more than one-quarter mile below the bridge.
The trees were pine (see specimens), oaks, Cupressus ?, Alnus along river.

Shrubs: Cornus along river.

Plants not collected but seen: Alnus, Smilax.

Fungi: Amanita rubescens, Russula (red topped), Panus, Lactarius, etc.

Soil was volcanic ash overlaying what appears to be sandstone .

Later: I am told that Venta is not the name of the river. I’ ll have to find out if I can.
