68 BOTANY OF SOCOTRA. 



Socotra. On the hills south-west of Galonsir. B.C.S. n. 140. 



Distrib. Endemic. 



A curious trailing plant, which is referred to this genus, with the majority 

 of characters of which it conforms; but it has a calyx quite exceptional in the 

 genus, and the winged pedicel is also an aberrant feature. An Abyssinian 

 plant C. (Phyllocalyx) Quartiniana, Baker (in Oliv. Flor. Trop. Afr. ii. 42), has 

 a large calyx of somewhat like character. 



2. PRIOTROPIS. 



Priotropis, Wight and Arn. Prod. 180 ; Benth. et Hook. Gen. PL i. 480. 



A genus of two species only, one of which is limited to the mountainous 

 regions of eastern India, and the other is Socotran. 



P. socotrana, Balf. fil. inProc. Roy. Soc. Edin. xi. (1882), 509. Tab. XV. 



Fruticosa; foliis trifoliolatis, foliolis oblongo-ellipticis obtusis emarginatis brevissime petiolatis; 

 pedicellis brevibus ; legumine longe stipitato longitudine dimidio latitudinem excedente 

 pubescente 2-spermo. 



Frutex 10-pedalis habitu Lulurni ramulis pubescentibus. Folia trifoliolata petiolo striguloso 

 1-1 f poll, longo ; foliola 1^-lf poll, longa §—J poll, lata oblongo-elliptica obtusa emarghiata 

 subapiculata brevissime petiolulata (petiolulo pil oso) supra glabra infra subtiliter brevissime 

 strigulosa membranacea conspicue curvatim venosa. Stipulce setiformes. Bacemi ter- 

 minates ramosi pilis brevibus adpressis vestiti ; pedicelli £ poll, longi bibracteolati, bracteolis 

 rninutis. Calyx poculiformis \ poll, longus extus pubescens, lobis acutis subsequalibus tubo 

 subsequilongis. Corolla longe exserta; vexillum unguiculatum subrotundatum eniarginatum 

 -fz poll, longum ; alae oblongae ; carina rostrata. Ovarium longe stipitatum compressurn 

 dense pilis adpressis vestitum ; stylus \ poll, longus lateraliter compressus. Legumen \ 

 poll, longum \ poll, latum pubescens 2-spermum compressurn, stipite calyci aequilongo. 



Socotra. A shrub of the higher levels on the Haghier hills. B.C.S. n. 

 688. Schweinf. n. 645. 



Distrib. Endemic. 



In this plant we have a species of a hitherto monotypic Indian genus. P. 

 cytisoides, Wight and Arn. (Prod. 180 ; Baker in Hook. Flor. Brit. Ind. ii. 65), the 

 species on which the genus was founded, is a plant of the tropical parts of the 

 eastern Himalayas — from Khasia to Sikkim, and the occurrence of this second 

 species in Socotra is an interesting fact of distribution. From the Himalayan 

 type the Socotran plant is distinguished by its obtuse not pointed leaves, and 

 by its shorter and narrower legumes. 



3. TRIGONELLA 



Trigonella, Linn. Gen. n. 898 ; Benth. et Hook. Gen. PL i. 486. 



A considerable genus of, frequently odorous, herbs, dispersed over Europe, 

 Asia, and North Africa. A few occur at the Cape, and one in Australia. 



T. falcata, Balf. fil. in Proc. Roy. Soc. Edin. xi. (1882), 509.
