MR. SCOTT ELLIOT S TROPICAL AFRICAN ORCHIDS. 



crisped median ruffles, rising 2 lines from the surface, run from 

 the entrance of the sac to within 6 lines of the rounded tip. The 

 short curved column {h in. long by 3^ lines broad) is prolonged into 

 a foot. The two large hollow pollinia are connate, and not separable 

 without tearing. 



Belongs to the group of large-flowered species which includes 

 L. giganteus Welw. (West Tropical Africa), L. jMrphyroglossus Kchb. f. 

 (Niam Niam and Monbuttu), and L. Welwitschii Rchb. f., from 

 Huilla. It is distinguished from all of these by the large thick 

 central lobe of the lip ; from the first also by its shorter bracts 

 and smaller petals, and the 3 strongly-developed ruffles on the lip ; 

 from L. Welwitschii by its more orbicular petals and shorter bracts ; 

 and from L. porjyhyroglossus by its somewhat larger flowers, thicker 

 spur, and blunt (not aristulate) bracts. 



Lissochilus papilionaceus, sp. nov. Speciosa racemo elon- 

 gato laxifloro, bracteis longe acuminatis, inferioribus linearibus 

 gradatim ad superiores lanceolatas transitum praebentibus, pedi- 

 cellos tenues cum ovario parvo excedentibus ; sepalis lanceolatis 

 acutis, lateralibus subfalcatis, petalis obovatis, sepalis jequilongis ; 

 labello basi saccato, calcare brevi, alls erectis late oblongis, lobo 

 medio breviter ovato, convexo cum carina mediana crassa antice 

 evanescente ; anthera caruncula brevi bifida coronata.

Tlie leafless flowering-stems are 2^ ft. or more in length ; the 

 scarious stem-bracts sheathing below, with a free acute upper part. 

 The racemes measure 11 in. ; the lower bracts are an inch or more, 

 the upper ^ in. long. The sepals have an abruptly acute plicate 

 apex, are 7-nerved, and 8J lines long by 3 broad. The petals are 

 5^ lines broad, with a minutely apiculate plicate tip. The wings 

 of the labellum are 3^ lines by 2^, with a rounded apex ; the 

 median lobe (5^ by 4 lines) has the characteristic plicate apiculate 

 tip. The blunt spur is only 1 line long. The rather thick footless 

 column is 2|- lines long. The anther is suborbicular. The two 

 pyriform pollinia (1 line long) are each partly split into two, and 

 attached to the ribbon-like stalk (1^ lines long) of the rostellum. 



Is near the Angolan L. PaivcE<mHS Echb. f., but has slightly 

 smaller flowers and ovate petals (in L. Paivceanus they are broader 

 and more rhomboid). The West African plant has also cuneate 

 sepals and shorter-pointed bracts, which do not equal the pedicel 

 and ovary. The allied Angolan species L. liensc/uanus Echb. f. 

 in Otia Bot. Hamb. 75, difl'ers (e descriptione) in having cuneate- 

 ligulate sepals, acute rhombic petals, and a lip with a subrhombic 

 ligulate central lobe.
