calyx about equally cleft before and behind, the lobes 

 about as long as the tube and cleft laterally but not so 

 deeply: corolla 12-15 mm. long, twice the length of the 

 calyx, white becoming purplish, curved funnel-form with 

 a pubescent line along the back terminating in a blunt 

 point between the united upper lobes; lower lobes all 

 alike, spreading, not saccate, somewhat longer, much 

 wider and more deeply divided than the upper, all cre- 

 nate : stamens included; the upper cell of each anther 

 twice the length of the lower: style thickened upward, 

 little shorter than the corolla: stigma disk-shaped, sub- 

 2-lobed: capsule oblong, apiculate. 



This plant differs from Orthocarpus, as Dr. Gray re- 

 marked, by its differently shaped corolla and included 

 stamens. NuttalFs Euchroma {Ortkocarpiis pallescen^ 

 and O. pilosiis) is. however, almost intermediate be- 

 tween Clevelandia and true Orthocarpus in the former 

 respect,

The flowers of Elytraria appear to have been little no- 

 ticed. In all our specimens the upper lip is bilobed, the 

 lower deeply 3-cleft, and each division bilobed. The 

 petaloid stigma is wider than either of the lobes of the 

 upper lip, and in vernation is folded over the stamens. 

 In the expanded flower it looks exactly like the third lobe 

 of the upper lip, and was undoubtedly mistaken for one 

 by (Ersted in " Mexicos og Centralamericas Acantha- 

 ceer," for in describing £^ . microstachya he says, " limbi
