long, nearly half as broad. — Mountain-precipice in Pansa- 

 mala, alt. 3,800 feet, May, 1887 (Ex. PI. cit. 1,226). — The 

 Bolivian S. triftartitum DC., which seems to be the most 

 nearly related species, has, among other differences, pisi- 

 form fruit. 



Tetranema evoluta. — Leaves membranaceous, retic- 

 ulate veins beneath and erose margins pubescent: peduncl - 

 ex-alate, shorter than leaves, sub-equalling paniculiform 

 scorpioid cymes, elongate axes 2-4-nate : calyx-segments at- 

 tenuate, 3-4 lines long : corolla nearly an inch long, white 

 with purple spots: capsule ellipsoid. — On rocks, Pansamala. 

 alt. 3,800 feet, May, 1887 (Ex. PI. cit., 1,218). — The generic 

 character drawn strictly from the sub-capitate umbelliform 

 inflorescence of the monotype, T. Mcxicana Benth , needs 

 enlargement to include this second species. The former 

 differs also by glabrous fleshy crenulate leaves exceeded by 

 margined peduncles, shorter calyx, smaller corolla, globose- 

 ovoid capsule.

xxiii, 284. — The author of this recent genus makes the fol- 

 lowing correction in one of its character^ : k4 The upper sepals 

 were described as distinct, and the three lower as united. 

 The reverse is the fact. The third broad and apparently 

 simple sepal is posterior, while the two lower, which remain 

 distinct, are lateral, one upon each side of the sac of the 

 corolla." In examining Dr. Watson's own undetermined 

 collections in Guatemala this plant has been found to occur 

 as "No. 292, Banks of Chocon river. Depart. Yzabal, March 



1885."
