as hardy as the other species of the pretty genus to which it belongs. It is 

 known in some collections under the names of P. jnyrtifolia and P. /ihilly- 

 resefolia. 



Jsclepia'Z)£^. — Morren\?i odordta Lindl. This curious plant has proved 

 as hardy as the Physianthus albens, which it very much resembles ; but differs 

 in having much larger cordate leaves and smaller flowers, as well as in the 

 botanical structure. The flowers are white, sweet-scented, and solitary. I 

 have never seen the fruit. 



ScROPHULARiA'cEiE. — Pauloivnia. hnperidlh Sieboldt. Flor. Jap., p. 27. 

 t. 10. A plant of this beautiful tree was raised in the garden of the Society 

 from seeds received from Japan in 1338. It has large cordate leaves very much 

 like those of the Catdlpa syringcEib\\2>. of North America, with which it was 

 considered identical by Thunberg ; but Dr. Sieboldt, who had an opportunity 

 of fully examining it, has formed the plant into a new genus under the above 

 name. The plant is quite hardy. 



THYMELA^CEiE. — T)dphne AucMdndW LincU. This fine species of ZJaphne 

 belongs to the same section as Daphne alpina with smooth lanceolate leaves. 

 It is evergreen, and was raised from seeds sent to the Society by Lord 

 Auckland from Kunawur, where it was found at an elevation of 12,000 ft., 

 and near the limits of perpetual snow. There is no such plant described by 

 Dr. Royle in his beautiful Illustrations of Northern India, nor does it appear 

 that the plant was known to Dr. Wallich ; but the ZJaphne viridiflora of Wal- 

 lich, and the D. mucronata of Royle, belong to the same section as D. Auck- 

 landii of Lindl. 



f/LMA^CEjE. — Sponia canescens, syn. 6^eltis canescens H. Sf B. This species 

 of the old genus Celtis was raised from seeds received from M. Hartweg, who 

 found it near Angancuco in Mexico : he says it will prove hardy. It very 

 much resembles in its present state C. australis, but is more downy, and par- 

 ticularly so on the under side of the leaves. 



i?ETULA'cE^. — A'lnus jorulensis Benth. PL Hart., p. 52. No. 392. This 

 very distinct species of alder was raised from seeds transmitted to the Society 

 by M. Hartweg, who collected them at a place called Zacualtipan in Mexico, 

 but the plant is common on the mountains of Jorula, and on the mountains 

 between the city of Mexico and Tampico. It much resembles J'lnus serru- 

 lata, but the leaves are 6 in. long and S^in. broad, and, like all the others of 

 the genus no doubt will prove quite hardy. M. Hartweg considered it a species 

 of -Betula, and a large quantity of the seeds received from M. Hartweg was dis- 

 tributed by the Society vinder that name ; but it is certainly a true species of 

 alder, and not a birch. 



Betula mollis Lindl. Bot. Reg. Mis., No. 169. for 1840. This singular 

 species of birch was raised from seeds collected in the Himalaya Mountains 

 by Dr. Falconer of the Saharunpore Botanic Garden. It is remarkable for 

 the softness of its leaves, which are roundly heart-shaped, and seems nearly 

 related to the i?etula alba pub^scens Arb. Brit. 



Betula Bhojputtra Wallich. Arb. Brit., p. 1714. The finest of the Hima- 

 layan species of birch, and certainly the most desirable. It was raised in the 

 garden of the Society from seeds, for which we are indebted to the Hon. the 

 Court of Directors of the East India Company. According to Dr. Royle, 

 this species occupies the loftiest mountains in the Himalaj'as, and the following 

 account is given of it in the Botanical Register for Oct. 1840, by Dr. Lindley. 

 " The epidermis of the betula Bhojpidtra is used by the mountaineers instead 

 of paper for writing upon ; it is of a very delicate texture, and peels off in 

 large masses, of which great quantities are brought down into the plains of 

 Hindustan, where it is employed for covering the inside of the long flexible 

 tubes of the apparatus used for smoking tobacco, cojjimonly called hooka. 

 The Sanscrita name of the substance is Bhoorja, in the Bengali language 

 Bhoorjapattra ; and Mr. Graves Haughton, Oriental Examiner to the Hon. 

 East India Compaoy, is of opinion that the word Bhoorja is the etymon of 

 Birch. It belongs to the same section as the paper birch of America and 

 very much resembles the B. ^:'apyracea."
