Aet. XXI. — Descriptions of two new Orchidaceous Plants from 

 Para. By Frederick Westcott, Esq., A.L.S., Honorary Se- 

 cretary to the Birmingham Botanical and Horticultural Society. 



The two new plants described below are natives of Para, where they were collected 

 by S. Dickinson, Esq. in the year 1839, and transmitted by him to George Barker, Esq. 

 in whose extensive collection at Springfield, near Birmingham, they flowered during 

 the present spring. 



Nat. Order. — Orchidace^. Tribe. — Malaxide^, Lindl. 

 Genus. — Pleurothallis, R. Br. 

 Pleur. barhata. Foliis lanceolatis, ovatis, apiculatis: sepalis subaequalibus, paten- 

 tibus, lateralibus reflexis, basi connatis, supremo subreflexo ; petalis sepalis 

 multo minoribus, subciliatis, acutis ; labello integerrimo, linguEeformi, me- 

 dio incurvo, apice acuto, carnoso, recurvo, supra glabro, subtus barbato. 

 Plant about 3 inches high. Stem smooth, angular, with 2 entire sheaths. Leaves 

 fleshy, smooth, keeled, the keel terminating below the apex and producing a point, the 

 older leaves have their margin more or less recurved. Flowers minute, racemose, va- 

 rying in number from two to many, as would appear from examining the old scapes. 

 Sepals rather ovate-lanceolate, smooth, rather obtuse, the lateral ones combined from 

 the base half way up, then free ; colour purple, except at the base, and if examined 

 with a glass of moderate magnifying power, they present a pretty papillose appearance. 

 Petals much smaller than the sepals, rather ciliate, acute, or perhaps approaching to 

 acuminate. Labellum entire and strongly bearded beneath, incurved in the middle ; 

 apex fleshy, acuminate, reflexed, and in colour similar to the sepals and petals. Co- 

 lumn smooth, about half the length of the petals, tipped with pui-ple at the back near 

 the apex. Clinaudrium slightly laciniate. Stigmatic cavity ovate. Pollen-masses 2, 

 pear-shaped. Anther-case smooth, 1-celled.
