IV. Ixora undulata. Roxburgh. 

 I. foliis lato-lanceolatis acuminatis undulatis, panicula laxa terminali, sepalis 

 acutis, filaraentis antheris aequalibus, stigmate bifido, baccis depressis. 



A branched shrub about four feet high, with compressed 

 glabrous branches, and ovate-lanceolate, acuminate, thin, 

 wavy, smooth leaves, seated on very short stalks. Flowers 

 white, or palish yellow, in supradecompound, brachiate, 

 downy, thyrsoid panicles. Calyx small and smooth. Corolla 

 with four linear, reflexed, obtuse segments, half the length 

 of the tube. Anthers linear and spreading. Stigmas two, 

 exserted. 



This is a desirable shrub in a collection of hot-house plants, 

 and is remarkable among the species of Ixora for the white 

 colour of its flowers, which passes away into a bright straw 

 colour. Brought to the Society from the Botanic Garden, 

 Calcutta, by Mr. John Potts in 1822. A tender stove-plant, 

 native of forests in Bengal, and flowering in this country in 

 June. Propagated like the last, but with rather more diffi- 

 culty ; and cultivated in the same manner. 



V. Diomedea argentea. Kunth. 



D. sericeolanata, argentea, foliis Janceolatis acuto-mucronatis basi angustatis 

 integerrimis. Kunth Synopsis II. 470. 



A half shrubby plant from two to three feet in height, with 

 round downy shoots, and opposite, entire, spatulate, distant, 

 caesious leaves, which often, by a contraction of one of their 

 sides, become a little distorted. The flowers grow singly 

 from the extremity of the branches, on long, clavate, some- 

 what angular stalks. The involucre is campanulate, and 

 double ; the outer of six or seven unequal, fleshy, occasionally 

 leafy divisions; inner equal to the outer in number, thin,
