	In 1934 John Thomas Howell published an account of a botanical ramble to [[LONE MOUNTAIN\|Lone Mountain]] and the Presidio that illustrates both the continuity and change in native plant communities. Compare the excerpt of his account from 1934 (printed below) with the botanical reminiscences of [[Botanical Reminiscences, 1891 \| Hans Herman Behr]] of the 1850s and [[Wildflowers \| Alice Eastwood]] of the 1890s.

	San Francisco is, in certain parts, still decked with bright bits of primal vegetation, and to an extent but rarely met with in centers where humanity becomes as densely concentrated. Although, as the years pass, the fringe of natural wildness is shorn more closely--here a boulevard, there a golfing green, and yet again a vegetable garden or a building--there still remain wild areas of sufficient extent to gladden the heart and mind of the field botanist. The marine cliffs at Land's End, the sandy downs and green serpentine in the Presidio, the red chert and clay slopes of Twin Peaks, the swales, dunes, and strand about Lake Merced, all of these carry still the same plant cover that was seen and studied by Chamisso and Eschscholtz, Bolander and Kellogg, Greene, Behr, and the Brandegees. At these places today, the student can still find plants first named from the vicinity, a number of which are narrow endemics, and most of which bear an endemic cast such as one meets in an insular flora. Although it is not possible to find in San Francisco all the plants first made known to the world from its hills and downs, it is probable that the majority can yet be located with a little search.

	Heartened by my find, I started for the Presidio, cutting down across the cemetery which flanks the mountain on the west. Here was change too: yawning holes of exhumed graves betokened the encroachment of the living on the city of the dead. Once in the Presidio I sought those slopes above the Marine Hospital and [[Mountain Lake 2000\|Mountain Lake]] where, it appears, Green, and no one else, collected his ''Allocarya'' in 1886 and again in 1887. Again success was mine for I found this most local species growing with ''Microseris bigelovii'' on a restricted clay flat near the summit of the ridge between the Marine Hospital and Fort Winfield Scott. A collection made, I took my way homeward down sandy slopes where low masses of ''Chorizanthe cuspidata'' (San Francisco spine flower) and ''Cryptantha leiocarpa'' were beginning to bloom and where plants of the autumn-blooming ''Lessingia germanorum'' (San Francisco lessingia) were becoming evident in opens between prostrate mats of the true ''Baccharis pilularis'' (coyote bush) and bushes of ''Ericameria ericoides'' (mock heather). It had been a day well filled.		Heartened by my find, I started for the Presidio, cutting down across the cemetery which flanks the mountain on the west.

	The desire to have again in the Herbarium of the California Academy of Sciences specimens of ''Cirsium amplifolium'' (=C. andrewsii, Franciscan thistle) took me last July to [[\|Lake Merced 100 years ago\|Lake Merced]] where the plant had been collected by Miss Eastwood before the fire of 1906 and again by Suksdorf in 1913. A diligent search along the eastern shores of the lake disclosed no extraordinary thistle, only the widespread ''C. edule'' (=''C. brevistylum'', Indian thistle) and ''C. occidentale'' (cobweb thistle) on open sandy slopes. For the time I had given up and had started home when I lost my trail on the floor of the narrow swale east of the southern arm of the lake and became entangled in the dense growth of willows, Californian Sweet Gale, and rank herbs. In this annoying predicament while bending every effort to force my way into the open, the desired plant was found, a single robust specimen well covered with heads of light rosy-purple flowers.

			\| colspan="2" \|'''Despite San Francisco’s rapid urbanization and dense population, diverse species of native plants shape and influence the city’s landscape and ecology, particularly in the Presidio — which is home to numerous rare and endangered fauna. In the city’s early years, San Francisco attracted naturalists and explorers, who sought to understand the biology of California and the west, and now their discovers are documented in numerous landmark publications on botany. Although modern development often infringes on these key species, the natural world is still heavily intertwined with life in SF.'''

	''The city of San Francisco harbors a quite diverse and impressive local flora despite its dense population. Its remnant natural areas feature a surprising number of native plant species. At the [[Rare Plants \| Presidio]], for example, approximately two-thirds of its indigenous flora--more than 260 native species--still remains, including 12 rare or endangered species. Though native plant communities are fragmented by buildings, roads, and tree plantations, they cover 145 acres of Presidio open space, more than 10% of its total area.

	Study of the flora reached a pinnacle with the assiduous work of California Academy of Sciences botanist John Thomas Howell and his young co-workers, Peter H. Raven and Peter Rubtzoff. In 1958 they published a landmark flora of San Francisco that documented the historic or present occurrence of 608 native and 447 non-native plant species. Tom Daniel, one of Howell's successors in the Academy's Botany Department, is preparing a new flora to be published sometime in the early 2000s.

	Two plants, long uncollected, led me afield last spring in the midst of the city. Can ''Amsinckia kelloggii'' [''A. spectabilis'', coast fiddleneck] still be found on the slopes of Lone Mountain, and has ''Allocarya diffusa'' [''Plagiobothrys diffusus P. reticulatus var. rossianorum,'' San Francisco popcornflower] been exterminated by the golf course in the Presidio--these were the particular questions to be answered. The quest led first to the mount which, until a few months ago, was a conical oasis of wild vegetation in a desert of streets and houses; but now on its truncated summit stands a school and its slopes have been so graded that scarcely aught remains of the native flora. It was with a doubt-filled mind that I trod the new-made ground and brushed past alien weeds crowding the freshly opened space with an alacrity which left the more tardy natives without a foothold. Passing on to a narrow border of the original undisturbed sand beside a fill of clay, a small colony of natives caught my eye. Here the ~~sand phacelia [~~''Phacelia distans''], the ~~trailing croton [~~''Croton californicus''], and the ~~dune~~ ''~~oenothera~~'' [''~~Camissonia cheiranthifolia~~''?] grew and, to my great delight, a few plants of ''Amsinckia kelloggii''. To show that the plant still grew where over sixty years before it was first collected, specimens for the Herbarium of the California Academy of Sciences were prepared as a permanent record for reference. At no other place did I find the plant on the mount; and, as I left, I wondered if the next sweep of the grader would snuff out forever this plant in its classic home.

In this annoying predicament while bending every effort to force my way into the open, the desired plant was found, a single robust specimen well covered with heads of light rosy-purple flowers.		The desire to have again in the Herbarium of the California Academy of Sciences specimens of ''Cirsium amplifolium'' (=C. andrewsii, Franciscan thistle) took me last July to [[\|Lake Merced 100 years ago\|Lake Merced]] where the plant had been collected by Miss Eastwood before the fire of 1906 and again by Suksdorf in 1913. A diligent search along the eastern shores of the lake disclosed no extraordinary thistle, only the widespread ''C. edule'' (=''C. brevistylum'', Indian thistle) and ''C. occidentale'' (cobweb thistle) on open sandy slopes. For the time I had given up and had started home when I lost my trail on the floor of the narrow swale east of the southern arm of the lake and became entangled in the dense growth of willows, Californian Sweet Gale, and rank herbs. In this annoying predicament while bending every effort to force my way into the open, the desired plant was found, a single robust specimen well covered with heads of light rosy-purple flowers.
