52. PSEUDERANTHEMUM PARVIFLORUM, Ridl., 11. sp. 



Suffrutex, glaber. Folia late lanceolata, herbacea, utrinque 

 acuminata, subtus pallida, 19 cm. longa, 7 cm. lata, nervorum 

 II paribus, petiolis i cm. longis. Panicula 15 cm. longa, rachi 

 pubescente. BractecB breves, i mm., lineares, acuminatae. 

 Pedicelli breves, vix i mm. longi. Sepala hirta, linearia, 

 acuminata, i mm. longa. Corolla i cm. longa, crassiuscula, 

 hirta, versus medium gradatim dilatata ; labium superius 

 lanceolatum, apice bifido, lobis lateralibus sublanceolatis 

 angustioribus ; labium inferius longius, carnosulum, lanceo- 

 latum, omnino parce hirtum. Stamina 2, antheris in dorso 

 hirtis, loculis baud parallelis inaequalibus, basibus mucronulatis. 

 Stylus glaber. Capsula 3 cm. longa, pedicellata, apice magno 

 dilatato acuto 7 mm. lato. Seniina 4, complanata, rugosa. 



Allied to P. breviflos (C. B. Clarke) Ridl., but differing in 

 foliage and habit. 



53. Leda lancifolia, Ridl., n. sp. [295]. 



Suffrutex, cortice pallido. Folia lanceolata, acuminata, 

 basibus longe cuneatis, sequalia, herbacea, 12 cm. longa, 5 cm. 

 lata, superne glabra, subtus in nervis minute scabro-hirta, 

 nervorum circiter 10 paribus tenuibus, petiolis i cm. longis. 

 Panicula terminalis, 6 cm. longa, ramis paucis patulis, 

 pauciflora. Bractece lineares, 4 mm. longse. Sepala linearia, 

 acuminata, acuta, 5 mm. longa, glabra. Corolla 15 mm. longa, 

 lobis labii superioris lanceolatis, inferioribus obtusis, lobo 

 medio pilis flavis munito. Stamina 2, antheris hirtis muticis 

 subparallelis. 



A single specimen with only one corolla remaining, but 

 enough to show that the plant belongs to the genus Leda, as 

 separated by C. B. Clarke, and that it is specifically distinct 

 from any other species. The inflorescence is open and 

 spreading, with a few branches and about 7 flowers on short 

 pedicels 2-5 mm. long. The whole of the leaves and panicle 

 dries black.

Apparently a large-sized form of this species, but without 

 flowers.
