28 BOTANiCAL GAZETTE. [ February, 



4-valved: seed i, oblate, an inch broad, half as high, black, 

 velvety. — Pansamala, alt. 3,800 feet, June, 1885 (Ex Pl. 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. Voy. Herald), and 

 which has not been cited by later authors : '' 683. Ipomoea 

 sp. Nomen vernacul. Boion de tercwpelo, Veraguas, The 

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

 densely covered with short, stiff, black hairs, giving them 

 the appearance of black velvet buttons," 



SOLANUM SIDEROXYLOIDES ScHLECHT, ,Var. OCELLATUM. 



Leaves elHptical, acuminate, base rounded, nearly smooth 

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

 placed by conspicuous black globose intramarginal glands. — 

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

 Schiede's original of Schlechtendars description has been 

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

 and fragments communicated by him. It differs only by 

 more manifestly ovate and acuminate leaves floccose beneath, 

 and minutely-toothed calyx. Tothe typical form seem re- 

 ferable 827 Botteri, 2,837 Bourgeau, 923 Tiirckheim ; also the 

 following unnamed specimens at Kew (not cited in Biologia 

 Cent7'alt-Americana)^ which have been compared by Dr. N. 

 L. Britton: 1,157, ^^7^ Galeotti ; 233 Linden : 855, 856, 

 857, 897 Botteri.
