10 Mr. T. Nuttall on a nevi species of Rhododendron. 



Act(Bon, and sundry other genera which have tooth-like plaits on 

 the columella, have opercula. 



Secondly, Mr. Benson must excuse me if I suspect he has 

 mistaken some adventitious membrane for an epiphragm, for I 

 have never seen a true epiphragm which extended " even over 

 the reflected portion on the pai-ietes " of the mouth ; indeed such 

 an extension is inconsistent with the manner in which the part 

 is deposited.

IV. — Description of a neio species of Rhododendron from Bootan, 

 in India. By Thomas Nuttall, Esq. 



Rhododendron Kendrickii. 



Frutex ramosus ; foliis oblongo-lanceolatis, acuminatis, glabris, con- 

 coloribiis, margine leviter midulatis, junioribus pubescentibus ; co- 

 rymbis multifloris ; laciniis calycinis niinutis, acuminatis ; (stami- 

 nibus 1 ?) filamentis glabris ; capsulis arcuatis, glabris, 6-lociila- 

 ribus ; semiiiibus lanceolatis, utrinque acutis. 



Hab. Mouutaius of Bootan (Mr. Booth). About 7000 feet eleva- 

 tion, accompauying R. Edgworthii, and found lower down than 

 R. Hookeri and R. FaJconeri, but above R. serotitmm. 



This fine species, having some affinity with jR. arboreum, forms 

 lofty thickets (after the manner of R. ponticum), through which 

 the traveller finds dark and difficult paths. The stem attains 

 the diameter of 7 or 8 inches, with a smooth pale bark. The 

 leaves, 4 to 6 inches long, are scarcely more than an inch wide, 

 elegantly waved on the margin in small plaits, so as to appear 

 almost crenate, disposed partly in whorls, equally green and 

 smooth on both surfaces when adult, the petiole less than half 

 an inch in length ; the young leaves and stems, in young plants, 

 more or less clothed with reddish glutinous hairs; beneath, 

 shining, with the pubescence chiefly confined to the midrib. 

 Flower-cone oval, the scales smooth, rounded and obtuse ; inner- 

 most scales or bracts silky. Corymb 10- to 12-flowered. Flowers 

 large, deep red. Stamens 10 ? smooth. Stigma 5-lobed. Calyx 

 small, as in R. arboreum, the segments bi'oad, ovate, acuminate. 

 Capsule 1 to 1:^ inch long, incurved, 6-celled, smooth and dark 

 brown. Seeds small, darkish brown, lanceolate, oblique, acute 

 at both extremities. 



It grows promiscuously with the very hardy Pintis excelsa, and 

 with several kinds of undescribed oaks. Found to be hardy in 

 the climate of England. Fresh flowers have not yet been seen,
