208 WallicNs Plants A&iaticce Rar-iores. 



in curries by the inhabitants of Chittagong (of which district of Bengal the 

 tree is a native), in the same manner as those of Dillenia speciosa (Chalta 

 of the Bengalese). The tree is in full foliage during the rainy season." — 

 Dilleni« ornata. A noble tree, sometimes mistaken for the teak, to which 

 it bears some resemblance in foliage. The flowers are large, fragrant, and 

 produced in great abundance. — Gastrochilus (labellum ventricose) *pul- 

 cherrimus; Scitaminese. Intermediate between Alpinia and Kaempferza. 

 Flowers very beautiful, delicate in texture, and pale yellow. — Gastrochilus 

 longiflorus. 



No. II. contains 



26 to 50. — Urena *speci6sa; ilfalvaceas. A very charming plant, 

 varying much in the form of its leaves, and with beautiful pink-coloured 

 flowers ; the corolla is nearly 2 in. long, and is by far the largest of the 

 genus, which has in general small and inconspicuous flowers. — Kaemp- 

 feria *elegans ; Scitaminese. — Justicza *guttata. — Dendrobium amplum ; 

 Orchideae ; and one of the most beautiful of the genus to which it be- 

 longs. " For the specific character and observation given I am indebted to 

 my inestimable friend Professor Lindley, who has undertaken, and in a 

 great measure accomplished, the elaboration of the families of Orchideae, 

 iJosaceae, and Amentaceae, in mj' possession ; and from whom I have, 

 besides, derived constant and important aid in the prosecution of this 

 publication, in the arrangement of the herbaria placed by the Honourable 

 East India Company under my charge, and in the distribution of their 

 duplicates. Many years, indeed, before I left India, have I benefited by 

 Mr. Lindley's generosity and kindness, to a degree which has placed me 

 under the most lasting obligations. I have long been desirous of an oppor- 

 tunity, and I seize the present one with great satisfaction, of expressing 

 publicly the sincere respect and gratitude which I entertain towards that 

 eminent and highly accomplished botanist." — Podocarpus *latif61ius ; Co- 

 niferae. A middling-sized tree, found on the lofty range of mountains 

 bordering on the eastern parts of Bengal. " It is probable that the juicy 

 receptacles are eaten, like those of the kindred species." — Ruellia alata. 

 One of the most charming species of the genus. — Knoxfa ^jlantaginea, — 

 Aphanochilus (ctphanes, obscure, c/ieilos, lip) polystachjais ; Labiatse. — A. 

 flavus. In this part of the work a .synoptical account of the Indian 

 Labiatae enumerated in Dr. Wallich's Catalogue of Dried Specimens is given, 

 for whicli. Dr. Wallich says, " I am indebted to my esteemed friend 

 Mr. George Bentham, to whom I am under very great obligations, both for 

 this important addition to my work, and for the valuable assistance he has 

 afforded me in my labours connected with the herbaria under my charge." — 

 Llparis longipes ; Orchideae — iJrica paniculata ; Orchideae. — Urdriacordi- 

 folia. — Coelogyne Gardnen'a?2« ; Orchideae. — Dendrobium *form6sum; Or- 

 chideae. — Dendrobium densiflorum. — /iconitum ferox ^F«//. The/iconitum 

 virosum of Don. P^-odr. Flor. Nepal. Found in Nepal Proper, at an ele- 

 vation of about 10,000 ft., and varying exceedingly, according to its habitat. 

 " There are three other species of aconite or monk's-hood, all of them 

 tuberous-rooted, which inhabit the southern side of the Himalaya, and are 

 considered by the natives as strong poisons. Our species, however, 

 exceeds them all in virulence, and is probably the most deleterious vege- 

 table poison of continental India. This dreadful root, of which large 

 quantities are annually imported, is equally fatal when taken into the 

 stomach or applied to wounds, and is in universal use in poisoning arrows, 

 and, there is too much reason to suspect, for the worst purposes." 



Mr. J. Pereira, of the General Dispensary in Aldersgate Street, London, 

 gave Dr. Wallich the " subjoined detail of several interesting experiments 

 made to determine the physiological effects of the roots of the Jconitum 

 ferox. They fully establish the extreme vkulence of the poison. These
