JDH describes his journey so far with Thomas Thomson [TT]. They have collected species of weeds, & fruiting branches of Calamus for RBG Kew. Discusses identification of plants with Martius & Griffiths descriptions. Lists species collected: C. rotang of Roxburgh, C. fasciculatus, rose of Bengal, R. involucrate. JDH sent 40 baskets of Orchideae & Rhododendron plants from Rampore to Bell in Calcutta [Kolkata]. Many plants died in Calcutta Gardens, including Jock Smith’s. JDH recommends a cool frame to grow them in England. JDH left larches at Darjeeling growing well, but sent all Rhododendron to Falconer. Comments on Thwaites’ new position [at the Ceylon, now Sri Lanka, Botanic Garden]. JDH suggests [George] Gardner neglected the gardens for the dried specimens. Discusses Thwaites’ plan for a collection of Cinghalese plants. Discusses Lord Torrington’s character. Describes sketches from Cathcart he is sending to Fitch in London: one of Kinchinjunga [Kanchenjunga] & the range around it from Major Crommelin, & a scene of a tree fern & Caryota with K[anchen]junga behind. Mentions the death of Mrs Turner. JDH expresses doubt about identification of R. thomsoni B. JDH hopes the dry specimens will allow Fitch to draw them. Discusses naming a plant after Strachey. Commends Dalzell's descriptions. Briefly mentions Cape Comorin [Kanyakumari] & Bombay [Mumbai]. JDH is disappointed African teak is not a Vitex.
