of Sir AYilliam T. TLiscl ton -Dyer, at Tlie Ferns, Witcoinljo, 

 Glcucoster, where the plant made a iine display iu April. It is a 

 hardy eA^ergreeu climber, with large leathery trifoliate leavt^s, and 

 showy axillary' cymes of white frag^rant flowers. It is allied to 

 C, Mcyeniojia, A\ alp., from which it may be easily distinguished 

 by the presence of a rosette of scales at the base of the infloresceiuv.^s. 

 The pretty Pleionc pogonioidcs was origiiiall}' described in 1896 

 under the name of Coclogyne pogonioides^ Holfe. II was firi^t col- 

 lected by Mr. T. Bullock in the province of An-Hwei and after- 

 wards by Mr. Augustine Henry on. mountains near Patung in 

 Hupeh. Living plants, which do not appear to have flowered, 

 tv'cre sent to Messrs. A^eitch by Wr. Wilson, Bulbs Avere received 

 from China in 1912 by Messrs. Charlesworth & Co., of Haywards 

 Heath, and the flrst flowers were produced in February, 1914, 

 when material Avas sent to Kew for identification and was used h\ 

 the preparation of the figure. This species and P. yunnanensisy 

 Rolfe, figured at t. 8106 of the Botanical Mag-o^^ine, are the only 



Chinese Pleioncs in cultivation. 



The Crataegus, represented in the illustration by a form in which 

 the leaves and stipules are larger than is usual in the species, is the 

 well-known Mexican Hawthorn or Tejocote, which is valued, espe- 

 cially by the Indians of Mexico, for its fruits, of which a national 

 conserve is made. It has a long history, being mentioned in the 

 writings of Hemaiidtz, who lived in Mexico between 1571 and 

 1577. In 1825 it was described by De Candolle as Crataegus 

 uieuticana, two years after Humboldt and Bonpland had published 

 a description of it as Mespilu-^ pubescens. It appears to h^ve been 

 introduced into England about 1824 by the eighth Lord Napier, 

 through his friend A. B. Lambert. A tree at Kew, now about 

 15 ft. high, was received from the Jardin des Plantes, Paris, in 

 1891. It is quite hardy and is one of the finest 

 cultivation. 



Salvia longistula, a Mexican species, resembles S. coccinea, 

 Linn., but its leaves and flowers are larger and the bilobed calyx 

 has long acuminate lobes. In height it is extraordinary, the Kew 

 plant being 14-15 ft. high after nine or ten months' growth. It 

 flowers during the winter, and where sufficient .space could be 



H 



given to it a plant would make an ornamental feature in the con- 

 servatory- The figure was prepared from material obtained from 

 the Kew plant, which was raised from a cutting presented by Dr* 

 liobertson-ProschoAvsky of Nice. 



The Ceratostigma is a new species which has been described and 

 figuz-ed from material sent to Kew by Miss Willmott, who has two 

 plants, now shrubs five feet high. It resembles the well-known 

 C, plumhaginoides, Bunge, often known in gardens under 

 Lindlev's name of Plvmhago Larpentae, but it is larger and 

 looser In habit, and differs in several less striking characters. The 

 home of C. W iUmoitianum is Western China, where it was col- 

 lected by ]\rr. E. H, Wilson for the Arnold Arboretum.
