PrENTSTEMON antirrhinoides, Benth. in DC. Prodr., vol. x. p. 594; A. Gray 
in Proc. Amer. Acad., Oct. 1862, p. 56. 
A very charming shrubby half-hardy plant, discovered in 
California by Dr. Coulter nearly half a century ago, and, as 
far as I am aware, found by no one since till Bolander 
gathered it in the Santa Maria Valley, San Diego. It is re- 
markable for the lemon-yellow colour of its flowers in a genus 
of which most of the species are red, violet, purplish, or blue, 
colours which rarely occur along with yellow in one group of 
closely allied vegetable forms, though mstances do occur (as 
Gentian). 
Pentstemon antirrhinoides flowered at the Royal Gardens, 
Kew, in September, 1874, from specimens sent by Mr. Niven, 
of the Hull Botanic Gardens. It is the twenty-fourth species 
figured in this work, out of upwards of fifty that have flowered 
in European gardens. The total number of species known 
in 1862 was sixty-four, of which an enumeration is given by 
Asa Gray in the Proceedings of the American Academy of 
Sciences, quoted above. ; 
Descr. A small, much-branched, glabrous, subcinereous

thulate, or oblong, or lanceolate, rarely linear-obovate ; obtuse
