38 Early Botanical Explorers on the Pacific Coast 
and others. He landed in San Francisco in 1849. Later he learned 
through Dr. Albert Kellogg, of the California Academy of Sci¬ 
ences, of the recent discovery of the big trees at Calaveras by a 
hunter named Dowd. At once he set out to collect specimens and 
seeds of this remarkable tree. He sent them to England, where 
the name Wellingtonia gigantea was given the tree by the bota¬ 
nist, John Lindley. Dr. Kellogg had sent specimens to Drs. Tor- 
rey and Gray and planned to describe and publish it as a new tree, 
but learned too late of the earlier publication. Lobb was a great 
collector and succeeded in getting seeds of almost all the trees 
that had been previously discovered in Western North America, 
many of which were first introduced to England from his seeds. 
Several species of plants are named in his honor. He died in San 
Francisco in 1863 and was buried in Lone Mountain Cemetery 
(now Laurel Hill). 82 His grave was located by the California 
Botanical Club several years ago, and the remains were moved 
to a new location and the grave put in good condition. 
John Jeffrey was sent to the Pacific Coast as botanical collector 
by the Scottish Oregon expedition, about 1850. The members 
raised the money by subscription, and each one was to receive a 
portion of the seeds. Jeffrey was expected also to keep a journal 
but failed to do so. He did very well at first but became neglectful 
and was later discharged. He collected over five hundred species 
of plants and sent seeds of most of the trees that had been brought 
to the notice of the world by earlier explorers. Pinus Balfouriana y 
Pinus Jejfreyi and Cupressus Lawsoniana (now called Chamae- 
cyparts) were first discovered by Jeffrey/ The last was collected 
on the southern flanks of Mount Shasta. It grows now near Shasta
