the plant came cannot be ascertained. Wallich’s Oudh

Out of these twelve the first fell into David Don’s hands, 
because Don was Lambert’s Librarian and had free access, with 
Hamilton’s knowledge, to the duplicate specimens that Hamilton |

Hamilton’s name of Swertia angustifolia with full acknowledg-

angustifolia, necnon S. pulchella et S. dichotoma, Linn. ? Hamil- 
ton MSS.,” which seems to show that Don had not seen a type of 
Hamilton’s S. pulchella.
