4-vahred: seed 1, oblate, an inch broad, half as high, black, 

 velvety.— Pansamala, alt. 3,800 feet, June, 1885 (Ex PI. cit. 

 744). Collected also by Dr. Sereno Watson (412 Fl. Guate- 

 mala. Yzabal, Apr. 1885). The tardily dehiscing capsule 

 exhibits scars of three obsolete ovules ; vestiges of the dissep- 

 iment appear in the form of a narrow ring encircling the 

 seed, free from both it and the septa, and attached only at 

 the conspicuous hilum. 



The eccentric seeds justify the conjecture that this is the 

 plant known only by its capsules in Kew herb., which is re- 

 ferred to as follows by Seeman (Bot. Vov. Herald), and 

 which has not been cited by later authors: "683. Ipomcea 

 sp. Nomen vernacul. Boton de tcrciopclo. Veraguas. The 

 capsule of this species is quite glabrous, but the seeds are 

 densely covered with short, stiff, black hairs, <rivin<r them 



the appearance of black velvet buttons." 



SOLANUM SIDEROXYLOIDES ScHLECHT. ,var. OCEELATLM . 



Leaves elliptical, acuminate, base rounded, nearly smooth 

 above, pubescent beneath, veins tomentose : calyx-teeth re- 

 placed by conspicuous black uloboseintramarginal glands.— 

 Pamsamala, alt. 3,800 feet, May, 1887 (Ex. PI. cit. 1,155). 

 Schiede's original of Schlechtendal's description has been 

 compared in the Berlin Herb, by Prof. Urban with the above, 

 and fragments communicated " by him. It differs only b\ 

 more manifestly ovate and acuminate leaves floccose beneath, 

 and minutely-toothed calvx. To the typical form seem re-
