"It is one of the greatest ornaments of the western mountains, and the natives make baskets, hats, pouches, bags, bottles, mats for sleeping on, &c., of its strong foliage."11
In his daybook, Douglas kept a running list of his collections that often revealed the depth of his awareness of who had come before him. When he saw the familiar evergreen shrub salal (Gaultheria shallon), he wrote "Called by the natives 'Salal,' not 'Shallon' as stated by Pursh, figure and description good; abundant (as is very correctly observed by Mr. Menzies) in all the pine forests."5 Here Douglas adjusted Pursh's account of a Corps of Discovery collection to fit his own hearing of Chinook jargon, then recalled the oral accounts of Archibald Menzies to reflect on the plant's range. He then added to the depth of the story by becoming the first of his cohorts to send viable salal seed back to England, where it was propagated and sold as a ground cover. The fact that salal has since escaped to spread across a variety of habitats in the northern British Isles as a noxious weed adds a modern twist to all these collectors' lore.
Having learned of the beautiful blue camas lily (Camassia quamash) from the writings of Lewis and Clark, Douglas paid close attention to the way local tribes dug, prepared, and cooked its bulbs even as he procured seed and packed his own dried bulbs in sand for the Horticultural Society. Douglas's field notes include one family's recipe for cooking camas in an earth oven, and he ended the account, as he often did, with a modest joke that included an historical nod to his predecessor. "Captain Lewis observes that when eaten in a large quantity they occasion bowel complaints. This I am not aware of, but assuredly they produce flatulence: when in the Indian hut I was almost blown out by strength of the wind."6
The Pursh handbook Douglas carried with him provided a direct line to virtually all of Lewis and Clark's plant collections, both the well-described and the mysterious. On July 19 of 1825, for example, Douglas departed from his Fort Vancouver headquarters in search of an undefined sedge, for which he had only a partial clue.
Early in the morning I left my residence in a small canoe . . . principally for the purpose of searching for and inquiring after the tuberous-rooted Cyperus mentioned by Pursh in his preface, the root of which is said to afford the natives food something like potatos when boiled. After a laborious route of twelve days along the shore north of Cape Disappointment, I was obliged reluctantly to return without being fortunate enough to meet with it. I observed several dead roots, washed on the shore by the surge and agreeing exactly with the description give by Lewis and Clarke, which I conjecture to be it.8
In a more positive light, Douglas obtained seeds for beargrass (Xerophyllum tenax, fig. 8), a Lewis and Clark favorite about which he could write: "The natives at the [Grand] Rapids call it 'Quip Quip.' Pursh is correct as to their making watertight baskets of its leaves."9
The single plant most often mentioned in the journals of the Corps was tobacco, including episodes in the Mandan villages, among the Shoshone, and at the mouth of the Columbia that involved tribal-grown smoking material "of their own manufacture." David Douglas was very curious about the origin of this tobacco, and began looking for it as soon as he arrived on the river. He collected information from fur trade workers about its spread, but only gradually homed in on native gardeners. "Whether its original habitats are here in the Rocky Mountains, or on the Missouri, I am unable to say, but am inclined to think it must be in the mountains," he wrote in fall 1825. "I am informed by the hunters it is more abundant towards them and particularly so among the Snake Indians, who frequently visit the Indians inhabiting the headwaters of the Missouri by whom it might be carried in both directions."10
When Douglas discovered a hidden tobacco plot on the lower Willamette River, he interviewed its Kalapuya gardener, then sent some specimens of the crop back to London. When compared with a sprig of tobacco that Lewis and Clark collected at the Mandan villages, it proved to be a cultivar of the same species, today known as Nicotiana quadrivalvis or Indian tobacco. The combined work of Douglas and the Corps proved that this species, a native to California, was part of a tribal trade network and extensive gardening practices that had been in existence long before white contact.12 Or, as Douglas put it in his comments to William Jackson Hooker, tobacco is "abundant within the recesses of the Rocky Mountains, and westward to the Pacific Ocean, in all dry light soils; it is greatly esteemed by the different tribes for smoking, and is the only vegetable which the native of the Columbia cultivate." 13

As Douglas moved inland, his mentions of Lewis and Clark continued as long as he followed their routes. Like the captains, he shot at harbor seals at the Cascades of the Columbia. For the name of the long portage known to Hudson's Bay Company voyageurs as The Dalles, he preferred "The Grand Rapids," as they were called by Lewis and Clark.14 When he saw the beautiful wildflower clarkia or elkhorn (Clarkia pulchella) that Pursh named for William Clark, he made sure to gather some good seed from it, and pack it carefully for transport aboard the Bay Company's supply ship of fall 1825. That same clarkia, in full bloom, became the hit of a fundraising plant sale the Horticultural Society held in London during the summer of 1828.15
Douglas himself did not board the fall 1825 ship that was supposed to provide his passage back to England. Intent on exploring inland, he wintered at Fort Vancouver and then spent most of 1826 circling the Hudson's Bay Company's interior posts. He called the Snake River "Lewis and Clarke's River," but for drainages upstream from there on the Columbia, he switched to a new source for geographical information: several of the fur traders he met had worked for North West Company agent and surveyor David Thompson, and although none of Thompson's writings or maps had been published at that time, these former crewmen provided Douglas with oral accounts of the surveyor's travels. When Douglas watched the voyageurs portage around an unnamed rapids a day's journey south of Kettle Falls, he suggested that they call the riffle Thompson Rapids after "The first [white] person to descend the whole chain of the river from its source to the ocean."17
In July of that same year, Douglas found himself back on the Lewis and Clark trail when he accompanied some fur traders to a Nez Perce encampment at the mouth of the Clearwater River. As he wandered the area in search of new plants, the collector chanced upon the "spot pointed out to me by the Indians where Lewis and Clarke built their canoes, on the way to the ocean, twenty-one years ago."18
