Dear Sir, 
| have two of your letters, the first from April 10; | received them during my trip to 
England and Paris, the second of June 6 has just arrived |! thankfully have the small 
booklet about Euphorbia sent by Mr. Mettenius, but the other booklet sent by Mr. Asa 
Gray and which should have been sent together with the Quercus of Mr. de Candoblle, 
probably remained in New York... The Quercus arrived at his house 3 weeks ago. We 
looked for but could not find the Euphorbia in the packagel!. | am desolate because 
there are not many species as important as this for me. The Euphorbia lucida, 
tetraspora, ocellata, etc. etc.did not arrive and | ask you dear Sir to replace this 
unfortunate package and send me another via the fastest route. In regards the 
installment, it has been of great help to obtain some species. | will send you all you wish. 
| a…m delighted to have been in Paris and specially in London where | found many items 
to write about. | also went to Leyden for the 3 species of Blumea and to Rostock to visit 
the herbarium of Lamarche. The Euphorbia indica Lam | have named E. cassioides 
Presl; the E. Braziliensis Lam is the Klotschiana Prel. the E microphylla is the thymifolia, 
duriforma, influtescens, etc. etc. 
| took samples from the herbarium of Michana. These were E. polygonifolia Mich., E. 
Curtisit and gracilis. The samples differ from the Curtissii. It is largely eliptic semina 
faveolata or punctata. 
| believe you have the E. paniculata Elliot or a variety of the corulata. Please tell me how 
you have studied this variety so that | can apply this knowledge to my samples. | 
presume that this insidious state is smaller and has more flowers. The Euphorbia kleinis 
Schlecht is not the corrigioloides. | could not adapt to these names when | did my 
studies. 
You talked to me about the E. coccinea Roth that you had seen at the herbarium of St. 
Petersburg. Âre you sure that you saw it at that herbarium? | was there for a long time 
and could not find it even after a most meticulous search. The E. coccinea could 
correspond to the description of Roth. Could you please send me the description that 
you have made? This singular species of Roth is not known here. The E. clusiaefolia 
Hook is entirely different from the E. Engelmanni (obliquifolia, depressa,). The E. Indica 
Lam-cassioides Piesi=Piesi=decumbens=-Wild=alcinoides Miquel. It is this form of 
Orientalis that one finally compares to the E. hypericifolia and which | find distinctive. It is 
really the E.parviflora Linn=(pap;;igera Boiss Cent.) This latter one has smooth seeds 
and under the magnifying glass has small areas of roughness.! 
The E. viscidula is in reality the E. Meyerniana, like the one | saw in Berlin. You have 
some samples that are of E. dioeca and E. adenoptera. It is the last name that | chose.
