REPORT ON ANALYSES OF SPECIMENS OF OINOHONA BARK. 

 Forwarded from Madras, t!iroiii/h Tier Majesti/'s Seo'etaiy of State for India, to the Tharmacev.tkal Hocidy. 



Natural Bakks fuom D.\ejeeling. 



(1) This and two following samples are from C. Condaminea, How. variety. 



(2) These botanical specimens and also the bark were taken from coppice shoots. 



(3) The bark belonging to this specimen is renewed, after the tree had been subjected to the Java shaving process 

 In this the outer cellular portion is shaved or pared off, the inner vascular layer being left intact. 



(4) Bark covered esternally with a thick corky layer, very peculiar, of officinalis type but undetermined species. 



(6) Large leafed or C. Vrilusiiiga, Pavon type. 



(7) This is the No. 2 variety, in the estate nomenclature; of the variety 0. angiuitifoUa, How. 



(11) This species was discovered by Has.skarl, cultivated on a large scale in Java and found to be worthless. From ' 

 Java it was introduced into India, where its culture never went beyond the stage of an experiment. 



(17) This plant was said by Cross, on his recent visit to the Nilghiris, to be the C ccjs/'" of which he sent seeds from 

 the Loxa Mountains. That it came from Loxa there is no doubt, as the few specimens of it on the estate of Dodabetta 

 are growing amongst the " crown "' barks introduced from that |region. It differ.s, however, very much from fhe (!. crispa 

 of Tafalla, which belongs to the C. ojjk-i}ialis group of Weddellj In general appearance it is more nearly allied to Wed- 

 dell's section I'aluidknue. Its bark is also very peculiar, in fa^ct unique. 



(20) This form of the C. Calisai/a grows to a considerable size and has bright green shining leaves, some of which 

 measure from 6 to 7 inches in length by 3J to 4 inches iu width. Flowers pink, very sweetly scented. 



(21) This plant approaches the Bolixiuiia form of AVeddel], but the CaJhaya^ are most variable. 



(23) This plant, according to Howard, is a hybrid between C. Calisaya and 0. si'cciruhra. On the other hand it 

 is said to come perfectly true from seed. Mr. Surgeon-Major Bidie thinks it to be only a variety of C. Calinaya. 



(26) This is not the C. pvhescens of Vahl. but a plant which was considered to be a hybrid by the superintendent of 

 the cinchona estates, the late Jlr. Mclvor. Mr. Cross regards it as the pubescent form of tkichicara," referred to by Dr. 

 Spruce in the Parliamentary Blue Book of 1SC3, p. 116. Mr. Mclvor stated that it is a hybrid between Cinchona .lucci- 

 rulira and Cinchona officinalis. 



(29) Pata de gallinazo of Cross.
