170 MR. R. spruce's visit to the cinchona forests 



completed its examination, especially that of its upper lip ; but as 

 ample characters are elsewhere furnished for its specific identifica- 

 tion, at least in relation to those already described, we may refer 

 it to the proper genus under the name of TJ, Benjaminiana. It 

 resembles U. injlata in size and the presence of a floating verticil 

 of abortive foliaceous axes on the lower part of the scape. 



U. Benjaminiana. Axis demersus ; fohis capillari-divisis sparse utricu- 

 liferis. Scapus infra verticillum natantem pilosus supra glaber esqua- 

 mosus 4-7pollicaris, vesicis 6-10 lin. longis lineari-lanceolatis utrinque 

 angustatis apicem versus segmentis capillaceis instructis, 6-multi- 

 florus. Bractea basifixse. PediceUi calycera parvum sequantes v. 

 duplo excedentes. Calcar denique 4-5 lin. longum, labio inferiore 

 coroUae duplo longius, apiee abrupte obtusum emarginatum. Capsula 

 minute apiculata, seminibus circiter 5 complanatis ala membranacea 

 anguste circumcinctis. Akentra injiata, Bj. Linna^a, xx. 319. 



Note. — ^I may add to the above the correction of some mis- 

 prints, &c., afi"ecting the sense, which I observe in my paper 

 on Indian Utricular ia^, published in the * Linnean Journal ' (Bot. 

 Proc. vol. iii. p. 170). Por ^^ aciculiferis'^ and " acicuUfera'^ 

 (pp.174, 175), read " utriculiferis,^' &c. ; "Bracteis ha&i-volutis,'' 

 read in all cases "solutis-,'' " volute ^^ also, in foot-note, p. 174, 

 should be " solute.'^ In the description of U. Wallichiana, p. 182, 

 line 7 from bottom, for "2-3-plo longiore''^ read " hreviore'' 



Notes of a Visit to the Cinchona Forests on the western slope of 

 the Quitenian Andes. By Eichaed Spruce, Esq. Com- 

 municated by Sir W. J. Hooker, F.E.S., P.L.S. 



[Eead Dec. 15, 1859.] 



My last letter informed you that I was contemplating an expe- 

 dition to the forests producing the Cinchona Tree on the western 

 slopes of the Quitenian Andes. I was for some time doubtful as 

 to what part I should visit — it was but two or three days' journey 

 to the forests of Jilimbi and Gruanujo at the western foot of Chim- 

 borazo, but to reach them the Paramo de Puenevata (the northern 

 shoulder of Chimborazo) has to be passed near the snow-limit, and 

 in the months of July and August it snows there almost inces- 

 santly, while the winds blow with a violence unparalleled even in 

 this windy region, frequently hurling away both horse and rider, 

 who are either seen no more, or their mangled remains are found
