Most Honored Sir ! 



r hope that you still remember me darklyy I had. the honor to make 

 your aquaintance about 17 years ago in Prague,where I was botanicall 

 custodian at the museumv You, also, visited my father f who has passed 

 away 6 years back 1 , and you were a Student of my grandfather Rudolph 1 

 in Berlin, I became in the meantime professor at the botanical ! f o'Üsst- 

 ry school in Weisswasser, and threw myself on the dendrology, Düring 

 the last years I occupied myself almost exclusively with the genus 

 Pinus and am preparing a monograph, f or whlchh professor Fenzl has pro- 

 vided' aeeeptance of the papers by the Viennese Academy% as there was 

 no other possibilityvf or Publishing due to the costly Illustration».. 

 After studying for a long time the microscopic anatomy of the Scalen 

 of the cones', the wood of the barkythe male flowers^ I limited myself 

 entirely on the epidermis, lengthP- and crosscuts- of the needles^ as 

 only in this wayv I have a Chance to objrain sufficient raaterialL IT 

 have examined the Pinus of the Viennese herbariumr the herbaria of 

 Willka (name incomplete on copy, E.D. ) »Reichenbacfr f is,Louder,Boissier 

 and have prepared: 1 preparatio ns of all 1 speeimens from different loc# - 

 litiesr. I further reeeived 1 live needleff from Vienna, Tübingen-, Berlin,, 

 Bbnrr, the Trade-Garden in Hamburg- and Erfurt and examined thenr,and 

 have completed' the illustrations of the old-world and some americarr 

 species, but T arn missing stilll about 20 species of the 6& contained 

 in the Prodnomuirr} and of many others I have examined only/ up to now 

 only cultivatedr ones or from only few localities. . I now take the li- 

 berty to ask you to assist me in my work', in providing^ some few nee - 

 dies- from each localityrin your herbarium^ of the desired species enumer- 

 ated on the reverse side. I know, I am asking much.for, thougfr your 

 herbarium will 1 not be robbed noticeably^y these needles t it does take 

 time to break off the needles and to wrap them into a paper capsule,.
