From J. S. Henslow  [5 November 1837 – March 1838]1

[recto:] 378 yellow =a prism of about 79 1/2— not yet ascertained what it belongs to2

[verso:] Ochrosia—as I am 〈    〉 〈p〉uzzled about your Keeling plant—3 the authorities give such [contradictory testimony] & even [it]


The date range is inferred from CD’s letter to J. S. Henslow, [4 November 1837], requesting the mineral specimen numbers and colours of the paper and the letter to J. S. Henslow, [26 March 1838], when the specimen (378 yellow) had recently been identified by William Hallowes Miller.
CD’s note about the specimen is in DAR 39.1: 88, in a catalogue of mineral specimens collected during the voyage. See letter to J. S. Henslow, [4 November 1837], n. 1 for CD’s numbering code.
Henslow found Ochrosia parviflora particularly difficult to identify from existing botanical sources, see Henslow 1838, p. 345.
