306 Report on the progress of the Horticultural Society, 



" lected on the same spot as mine by the late Dr. Schiede, who 

 " gave it the name of P. oocarpa." 



The box No. 16 mentioned in the above letter is missing, it does 

 not appear ever to have reached Vera Cruz. 



No. 24.— Real del Monte, November 20th, 1838.—" By the first 

 " convoy that leaves the city of Mexico, I will endeavour to send 

 " part of the seeds that are now in my possession ; but I think it is 

 " a bad speculation to send small parcels, they being very apt of 

 " getting lost. Mr. Ehrenberg sent two little boxes of seeds last 

 " year, one of them never reached its destination, and the other 

 *' only empty. I made some enquiries about the Radix mechoacana

 " new species of Mali on ia, a Garrya (the third species which I found 

 " now, but only about a dozen half ripe seeds) two Vaccinia, one 

 <f Clethra, an Andromeda, a Viburnum, 2 Cornus, 1 splendid Capri- 

 " folium, the true Convolvulus Jalapa, another trilobed Convol- 

 " vulus which also yields the Jalap, both with purple flowers, a 

 " large white Ipomaea, some acorn?, Cereus senilis and many other 

 " Cacti, with Parkinsonia aculeata, and a Valeriana with a very large 

 " root, which crushed and mixed with pulque, is employed by the 

 " natives against fever, but I am not aware with what result. About 

 " ten days ago when returning from one of these excursions late at 

 " night and about 1^ league of this place, I was accosted by a per-
