Early Botanical Explorers on the Pacific Coast 37 
Cupressus macrocarpa had been given to Lambert and named by 
him but never published, and where the seeds came from was un¬ 
known. Hartweg also collected Quercus chrysolepis y at Mon¬ 
terey, which was described from his collection. He tried to obtain 
seeds of the Santa Lucia Fir, Abies venusta , but found them 
frozen. He visited Sonoma, where he discovered Quercus Kel- 
loggii . Later he went into the foothills of the Sierra Nevada, near 
the present site of Marysville, and was the first to make known 
plants from the Sierra of California. The results of his collection 
were published by George Bentham under the title, Plantae 
Hartwegianae . 30 In the Quarterly of the California Historical 
Society for December, 1933, is a reference to Hartweg in “The 
Memoirs of Theodor Cordua.” 31 Cordua accompanied Hartweg 
on trips and gives a lively, interesting account of one they made 
together to Bear Valley. On this trip, Hartweg collected the 
Knob-cone Pine ( Pinus attenuatd) and many species well known, 
such as the prostrate Ceanothus (Mahala Mats), Chamaebatia 
foliolosa (Mountain Misery), the yellow-flowered Honeysuckle 
(Lonicera interrupta ), the red Fritillaria recurua and the com¬ 
mon Brodiaea capitata . B 
William Lobb began his career as a gardener, and while in the 
employ of William Veitch, who had a large nursery at Exeter, 
England, became greatly interested in botany. He showed such 
intelligence and ability that Veitch sent him to South America to 
collect seeds and plants. He was then 31 years of age and spent 
several years in Mexico, making valuable collections. Veitch next 
sent him to the Pacific Coast of North America, especially to col¬ 
lect seeds of the trees discovered by Menzies, Coulter, Douglas
