not seen one yet. I have selected oaks as a very characteristic type. 

 The same holds with respect to the plants that are associated with 

 the oaks, &c. about Mussourie. In the lake you see Nelumb'mm 

 a.nd Euryale/erox, growing along with. Menyanthes trifoliata; and 

 cotton, a poor sort, growing on the banks, while the sides of the 

 bounding hills are skirted with pines. 1 got Staphylca Emodi grow- 

 ing along with Ribes Grossularia (your Himalense }), while it grows 

 as you know at Mussourie on low slopes near Budraj. The Prangos 

 pahularia grows in the valley. I found it most abundant on Ahatoong, 

 a low trap hill on the valley, but it is not so vigorous a plant as in 

 its Thibetian habitat. I expect in the summer to get as far north 

 as lat. 36° at the least on the Kuenlun or Kara Korun range, a 

 most desirable tract to explore, as it will be clear beyond Hima- 

 layan vegetation, partly characteristic of that of central Asia. I have 

 already seen enough to convince me from a trip to the Thibet 

 frontier to near Durass, that the Flora ahead will bear a close re- 

 semblance in many general relations to that of the Altai Mountains 

 shown by Ledebour and yourself." 



" Deosir, Cashmeer, June 20, 1838. 



" I have written to you twice from Cashmeer. I have been going 

 leisurely all round the valley, and into all the subordinate valleys 

 which radiate on all sides from the great one. I have made many 

 acquisitions. Among Ranunculacece I have got species of Hepatica, 

 Ceratocephalus, and Callianthemum, all of which I believe to be new, 

 and making up the very blanks you notice in your ' Illustrations.' 

 Of Callianthemum, I have no knowledge, besides your quotation, but 

 ray plant has leaves with umbelliferous habit, 8 white strap-shaped 

 clawed petals, with the nectariferous pore high up on the claw, and 

 n pendulous ovulum. It cannot therefore be a Ranunculus, nor your 

 R. pimpinelloides. Further, I have got a new Ranunculaceous genus, 

 new unless Jacquemont has got it, having the habit of Trollius in its 

 leaves and mode of inflorescence, 8 herbaceous sepals, 24 strap- 

 shaped petals, plane with no fovea at the claw, and solitary trans- 

 versely attached ovula, being neither pendulous nor erect. It forms 

 a transition from Adonis to the Ranunculem. This is another 

 blank filled up in the desiderata so pointedly mentioned by you. I 

 have called the genus Chrysocyathus. It grows intermixed vvith 

 Trollius, ' inter nives deliquescentes,' and till I examined it I took it 

 for a Trollius. I have got a new species oi Adoxa, forming I believe 

 the second of the genus, A. inodora (mihi), a larger plant than 

 the A. Moschatellina, and with the lateral flower 12-androus, and
