INTRODUCTION clxV 



ihe Professorship of Botany in Cambridge had been a sinecure for 

 thirty years, Henslow was appointed Professor, Darwin, Berkeley,- 

 and Babington being among his pupils. In 1832 he became Vicar of 

 Cholsey in Berkshire, but he only resided there during* the Long 

 Vacation. In 1837 he was presented to the Crown living of Hitcham, 

 in Suffolk, and in 1839 he left Cambridge for that place, and died 

 there in 1861. There is a marble bust of him in the Kew Museum, 

 and a lithograph portrait by Maguire in the Museum at Ipswich. 

 A memoir by L. Jenyns, with u portrait, appeared in 1862. The name 

 Henslovia was given to a genus of the Santcdaceae by Blume ; a genus of 

 Lythrariaceae was named by Wallich Henslowia, but it is now the 

 Cnjpteromia of Blume. 



Professor Henslow issued a Catalogue of British Plants in 1829 and 

 a second edition in 1836 ; his Dictionary of Botanical Terms was published 

 in 1857. A more detailed account of his life and publication^will be ' 



found in the Dictionary of National Biography, from the pen of Mr. 

 Boulgcr. Several of his plants are preserved in the Town Hall 

 Museum of Northampton. I have found few traces of his work in 

 Berkshire ; he records the discovery of Lythrum Hyssopifolia and of 

 Peucedanum sativum at Cholsey. 



KicHARD Walker, B.D., F.L.S., author of the Flora of Oxfordshire, was Walker, 

 born at Norwich on March 17, 1791, and was educated at the Free R- 

 School of that city, under Dr. Forster. He was the son of the Rev. 

 John Walker, Minor Canon of Norwich. In 1810 Richard matriculated 

 at Balliol College, Oxford, and in 1812 became Demy of Magdalen 

 College ; he took his B.A. degree in 1814, his M.A. degree in 1817, and 

 his B.D. degree in 1824. In 1821 he became a Fellow of his College, 

 of which he was subsequently Dean, Bursar, and Vice-President, and 

 was Master of the Grammar School attached to the College from 1828 

 to 1844. He was ordained Deacon by Bathurst, Bishop of Norwich, 

 and Priest by Fisher, Bishop of Salisbury. He was for some time 

 Curate of Tilehurst, near Beading. In 1852 he married Eliza Naomi, 

 daughter of David Davies, M.D. He died on December 31, 1870, and 

 was buried at Olveston, near Thornbury in Gloucestershire. His 

 herbarium is said to have been in the possession of his widow, who 

 resided at Bath, but I have been unable to confirm the statement. 



The Flora of Oxfordshire and its contiguous Counties was published in 

 1833 ; it did not add many plants to the existing lists for Oxfordshire 

 or Berkshire, and the comparatively few additions to either county 

 were almost entirely contributed by other botanists, and especially by 

 Mr. Baxter! The Flora is arranged according to Linnaeus' artificial 

 classification, and the species are described in plain and easy language, 

 Mr. Walker wishing probably to make a special feature of supplying 

 a book in which the plants of the district should be described, rather
