The copy in question was evidently utilised in the preparation 

 of an old list of determinations from which the localities given in 

 .Vidal's Phanerogamae Cumingianae Philippinarum was largely 

 extracted, but the inclusion of numbers cited from other sources 

 has introduced a number of contradictions, so that great uncer- 

 tainty exists as to many of the localities. 



From the preceding it is clear that Cuming used no field 

 numbers, and that the distribution numbers were not added until 

 after the ferns and other Cryptogams, Orchids, Figs and some 

 others had been separated. These numbers were given as the 

 bundles were successively distributed, and only partially indicate 

 the sequence in which the places were visited. With the 

 information now published it might be possible to eliminate some 

 . of the errors by a re-examination of the original tickets, but it is 

 doubtful whether the material for a complete itinerary is in 

 existence. The correspondence shows that some such journal 

 was prepared by Cuming and submitted to Sir William Hooker 

 with a view to publication, but was returned as unsuitable. Its 

 subsequent history cannot be traced. 



An attempt has been made, in the light of the above corres- 

 pondence, and with the aid of Sir William Hooker's original list 

 of determinations, to trace the localities of the extra-Philippine 

 numbers but only with partial success. Among the flowering 

 plants the earliest numbers for Sumatra, Malacca, Singapore and 

 St. Helena have been found, and all are carefully localised by 

 Cuming himself, as described above. This shows that numbers 2252 

 to 2399 are from Malacca, 2400 to 2427 from Singapore, 2428 to 2443 

 from Sumatra,* and 2444 to 2464 from St. Helena. Besides these 

 errors there are certain others, arising from the fact already 

 mentioned that certain groups had been separated before the 

 numbers were added. Very few indications of what these are can 

 be found in Sir William Hooker's list. But there are the 

 following respecting the Vascular Cryptogams : — 3(53 to 368, 

 Singapore ; 369 to 407, Malacca ; 420 to 429, St. Helena. No 

 indications of Sumatran ferns can be found, either here or in Smith's 

 Enumeratio Filicum Philippinarum, which also included Cuming's 

 extra-Philippine numbers. These numbers require confirmation 



because 369 and 420 

 while 363 has not been 



as Sumatran Algae, and 2443 is carefully localised on the ticket by 

 Cuming himself. A few other numbers are localised in pencil, 

 and in a tentative way, on the list, but as the corresponding 

 determinations are not entered it is impossible to verify them, and 

 the only practicable course would be to compile a new list from 

 the original tickets as the missing specimens come to hand. 



are not localised by Cuming on the ticket,
