Eemarkable for its small linear leaves and delicate habit.

 subacutis, petiolo brevi vel ad 1-3 cm. longo, stipulis lanceolatis 

 acuminatis 7 mm. x 3 mm. infra medium bifidis ; florihus parvis

Differs from all other species known to me in the habit, which 

 closely resembles that of many Psychotrics, as also in the bifid 

 stipules. De Candolle (Prodr. iv. 481) described a plant which he 

 named suggestively D. ? i^sycliotrioides, expressing, however, a 

 doubt as to the genus, as no flowers were present. This also has 

 bifid stipules, according to the description ; but they are said to 

 be subulate, the peduncles short, the inflorescence falling con- 

 siderably short of the leaves. De Candolle gives as localities for 

 D. 2^sychotr hides, Cayenne {Pair is), and Panama and Mexico 

 {Haenke). 



LiNDENIA. 



The genus Lindenia is an interesting member of the tribe 

 PhOndeletiea, with long-tubed, showy flowers. Two species have 

 hitherto been known from the New World, L. aciitiflora and 

 L. rivalis, both natives of Central America, and forming the 

 respective subjects of plates 475, 476 in Hooker's Icones. The 

 genus comprises two other species, L. austro-caledonica Brongn. 

 and L. vitiensis Seem., the locality being indicated in each case 

 by the specific name. 



The flower typical of Lindenia recalls that of the large- 

 flowered MussandcB with subequal calyx-lobes. The two following 

 species are very distinct from those previously described ; both 

 are preserved in the Kew Herbarium, to the authorities of which 

 I am greatly indebted for the privilege of examining the material.
