OF THE MATTO GROSSO EXPEDITION, 1891-92. 295 
M. Glagiou. Moreover, a number of A. St.-Hilaire’s types have recently been presented 
to the Thames-side institution. I take this opportunity of expressing my conviction 
that, when one remembers the comparatively small amount of attention devoted by 
Britishers to the Brazilian flora as contrasted with their energy elsewhere, one has every 
reason to be proud of both our National Herbaria, which, although probably not so rich 
in plants of Brazil as the kindred establishments at Berlin and Paris, do certainly afford 
help quite invaluable to the student. 
It were to shirk a pleasant duty to end this introduction without recognition of kind- 
ness received from many quarters in the course of my work. Thanks are especially due 
to Mr. Carruthers, who allowed the plants to be stored at and distributed from the 
British Museum, and who, in every other possible way, has furthered my labours. 
Mr. Carruthers also examined and confirmed my determination in respect of the only 
Cycad in the collection. The other members of the Museum botanical staff have, each 
in his special department, most obligingly permitted me to take advantage of their 
knowledge. Iam indebted to the Officers of the Linnean Society for kindly seeing the proofs 
of this memoir through the press in my absence from England. All my friends at Kew 
without exception, from Mr. Baker downwards, were ready with help in cases of difficulty ; 
and more than once, when thoroughly beaten owing to the imperfect state of a specimen, T 
was put upon the right track by Professor Oliver. Mr. C. B. Clarke very kindly undertook 
the Cyperaceze, an order upon which he has bestowed an immense amount of time and 
trouble; Commelynace:e also were determined by the same botanist. Mr. Scott Elliott 
looked at the Figs, and indicated the novelty and affinity of one of these. Mr. Daydon 
Jackson allowed me to consult advance sheets and MSS. relating to his great “ Index 
Kewensis,” and this saved me much trouble, and prevented some errors. Nor must I omit 
the names of several foreign botanists, who were good enough to examine and compare 
certain specimens and send information on critical points; the list is, I believe, 
exhausted on mentioning the following :—Professors Engler and Raa'kofer, Drs. Schu- 
mann and Taubert, of Berlin, Dr. Warburg, and the late Dr. Morong. To these 
gentlemen my best thanks are here recorded. 
To Lieut. Olaf Storm and Mr. John Storm I am greatly obliged for doing all in their 
power to further my work in every possible way, and also for allowing me to make use 
of the map accompanying this memoir. Dr. Evans, Mr. Holden, and the other 
members of the expedition rendered me much kind assistance, which I here gratefully 
acknowledge. 
I have also to acknowledge indebtedness to the Royal Meteorological Society, 
through their courteous Assistant Secretary, Mr. William Marriott, for the opportunity of 
access to records relating to the climate of Brazil. Nor should the great pains taken by 
Mr. R. Morgan with the plants figured be left unmentioned. 
Of the plants, the first set, with notes, &c., goes to the British Museum, the second 
set to Berlin, and the third to Columbia College, New York; Vienna has the fourth, 
and Kew the fifth. Small sets have also been sent to Paris, Rio de Janeiro, and 
Edinburgh.
