the upper side, very closely and softly tomentose on the under where 

 the veins are strong and prominent ; petioles toraentose, about 2 inches 

 long. Panicle rather small, thyrsoid, terminal, tomentose, leafless, 

 shorter than the upper leaves. Calyx coarsely tomentose all over; 

 the limb with 5 sharp teeth. Corolla coarsely tomentose externally, 

 with the tube about 3 times as long as that of the calyx ; the limb 

 smooth inside except just at the edges which are tomentose. There 

 are two specimens of this in Mr. Lambert's herbarium, one of which is 

 marked by Pavon " vulgo Azahar ; " another is in Dr. Thomson's pos- 

 session, proving it to be a species perfectly different from all others. 

 Upon what information, unless that of M. Zea, this very striking 

 species should, contrary to all evidence, have been supposed to be the 

 C. oblongifolia of Mutis I am unable to state. Mutis expressly states that 

 his C. oblongifolia has smooth leaves. It has nothing to do with that 

 species, which is C. magnifolia, and its bark is unknown. It stands 

 nevertheless, in the latest edition of the London Pharmacopoea, as 

 yielding one of the barks directed by the College of Physicians to be 

 employed in the shops.

Shoots quadrangular, when quite young covered with a fine soft 

 down. Leaves ovate-lanceolate, acuminate, acute or obtuse at the base, 

 coriaceous, very even, a little wavy; with midrib and the veins of the 

 underside covered with long fine hairs, especially at the axils, which are 

 not scrobiculate ; the uppermost leaves much narrower than the lowest. 

 Inflorescence leafless, tomentose. Calyx tube very tomentose ; limb 

 pubescent, deeply divided into long narrow channelled obtuse teeth. 

 Corolla almost smooth, much longer than the calyx ; the segments of 

 the limb smooth inside, except at the edge which is covered with a short 

 close down. Of this I have only seen some fragments in Mr. Lambert's 

 herbarium. One of the worst species for medicinal purposes; it is 

 found sometimes in parcels of other barks. R. and P. Jt does not appear 

 to have any vernacular name. Ruiz in his MSS. asserts that it does not 

 deserve any attention for medical uses.

Young branches quite smooth, terete, scarcely at all angular. Leaves 

 oblong, sometimes narrowed towards the base, obtuse, often as much as 

 a foot long exclusive of the footstalk, coriaceous, strongly ribbed, 

 flat, shining on both sides, and quite free from hairiness, unless when 

 very young, except upon the principal veins and at their axils where 

 there is always a tuft of rather long hairs. Flowers in a large terminal
