4 MR. G. D. HAVILAND: REVISION OF THE NAUCLEER. 
by Roxburgh. At first many specimens of different species were 
named .Vauclea orientalis; there is a specimen of Mitragyna 
parvifolia so named in the Banksian Herbarium, and referred to 
by Gaertner in 1788, ‘De Fructibus; i. p. 151. Mr. Daydon 
Jackson is of opinion that the name is probably not Linnzus's. 
The only other specimen in the Herbarium labelled Nauclea is 
one of Adina globiflora; and Mr. Jackson thinks the writing in 
this case is undoubtedly that of Linneus. The genera Uncaria, 
Sarcocephalus, Adina, and Mitragyna have since been formed, 
and plants have been removed from the original genus Nawclea. 
It was not until 1888 that Dr. Trimen (Journ. Linn. Soe. xxiv. 
pP- 136) pointed out that No. 53 of Linneus’s Flor. Zeyl. was 
Sarcocephalus cordatus, Miq. 
Aublet in 1775, * Hist. Plant. dela Guiane francoise,' i. p. 177, 
described and figured Ourouparia guianensis, and pointed out its 
relationship to the ** daun gutta gambir” of Rumphius. In 1789 
Schreber, in his edition of Gen. Pl., acknowledged Aublet's genus 
but renamed it, substituting Uncaria for Ourouparia ; and that 
name has come into general use, though Baillon, K. Schumann, 
and others have recently returned to Ourouparia, sometimes 
writing it Uruparia. I shall regard Uncaria and Ourouparia as 
absolutely equivalent. In the Linnean Society's * Transactions ' 
for 1808 Dr. Hunter, under the name Nauclea, described three 
species of Uncaria, and made no reference to Aublet’s deseription 
of the American Uncaria; Roxburgh was the first in Asia to 
distinguish Uncaria from Nauclea. Blume, however, reunited 
them, and DeCandolle, though he separated them again, did so 
with hesitation. 
Salisbury in 1807, Parad. Londin. p. 115, founded the genus 
Adina on the Chinese species Adina globiflora ; but it was long 
before the value of the genus was recognized. DeCandolle makes 
two species of Adina out of Adina globiflora, but other species he 
leaves in the genus Nauclea. Smith, in ‘ Rees’s Cyclopedia,’ and 
Baillon, in ‘ Adansonia,’ reduce the genus back to Nauclea; 
Bentham, in the ‘Flora of Hongkong,’ points out an Indian 
species of Adina; and others are indicated in Bentham and 
Hooker’s ‘ Genera Plantarum. In the ‘ Flora of British India’ 
Sir Joseph Hooker placed two species in Adina which, though 
in some respects intermediate between Adina and Nauclea, seem 
to me best classed with the latter genus.
