406 LXIV. ERICACEAE [Pentapterygium 



A. L. small, pedicels solitary or in pairs, anthers not spurred. 



1. P. serpens, Klotzsch ; Wight Ic. t. 1183 ; Hook. f. 111. Him. PL t. 15 b. Sikkim, 

 3-8,000 ft. Bhutan. Base of stem large, tuberous, branches pendulous, hispid, densely 

 leafy, 1. glabrous, bifarious, margins recurved, corolla J in. long, tubular, bright red 

 with V-shaped marks. 



B. L. large 2-5 in., pedicels fascicled or corymbose, beaks of anthers spurred. 



2. P. rugosum, Hook, i . Khasi hills, Bhutan. L. serrate rugose, sec. n. very prominent, 

 corolla | in. white or rose. 3. P. Listeri, King. Bhutan 7,000 ft. L. nearly entire, not 

 rugose, corolla i in., rose. 4. P. flavum, Hook. f. Bhutan. L. rugose, slightly crenate, 

 corolla § in., yellow. 5. P. Hookeri, Clarke. Sikkim 5-8,000 ft. Bhutan. L. serrate, 

 corolla § in., yellow. 



Desmogyne neriifolia, King et Prain ; Ann. Gard. Calc. ix. 46, t. 59. China. 

 Kachin hills. Upper Burma. An epiphytic shrub, 1. lanceolate, blade 4-5, pet. J in. 

 long. Fl. in axillary corymbs, bracts small, pedicels enlarged below the calyx into a 

 cup, partially enclosing calyx-tube (connate bracteoles?) Calyx-limb inflated, wide 

 campanulate, reticulate, margin entire, corolla li in. long, lobes short, fr. crowned by 

 the persistent calyx-limb. The authors of this genus (Journ. As. Soc. Bengal vol. 67. 

 298) justly observe that Ayapetes, Penlo-pteryyium and Desmogyne might be united. 

 In that case the present species would belong to the section of Ayapetes, represented by 

 A. auriculata (p. 405). 



3. VACCINIUM, Linn. ; Fl. Brit, Ind. iii. 451. 



Shrubs or small trees, a few species epiphytic, 1. coriaceous. Fl. usually 

 small, generally in racemes, rarely solitary. Racemes in bud often covered 

 by the imbricating bracts. Corolla campanulate cylindric or ovoid, lobes short, 

 anthers oblong, often spurred at the top, produced into 2 cylindric tubes 

 opening b} r terminal slits. Seeds ellipsoid, testa firm, shining, minutely foveo- 

 late. Species 100, Northern Hemisphere and mountains in the Tropics. 



A. L. large, racemes solitary. 



a. L. lanceolate, serrate, mostly falsely whorled. 



1. V. serratum, Wight Ie. t, 1184; (Gaylussacia serrata, Lindl. ; Boyle 111. t. 79, 

 fig. 2.) Sikkim 4-9,000 ft. Khasi hills. A shrub, often epiphytic, stem often thick, 

 tuberiform, 1. often approximate near the ends of branchlets (falsely whorled), lanceo- 

 late 3—4 in. long, gradually narrowed into a very short petiole. Fl. greenish-white, 

 racemes several at the ends of branchlets, bracts small, linear. Corolla J in. long,

 white or yellowish, £ in. diam. 2. V. venosum, Wight Ic. 1. 1185. Sikkim 4-7000 ft. (the 

 hispid form). Bhutan, Khasi hills. Branchlets sometimes hispid, 1. sessile with a rounded 

 base or suddenly narrowed into a very short petiole, sec. n. prominent. Racemes 

 several near the ends of branches, peduncles with numerous persistent elliptic bracts 

 at their base. Filaments glabrous, anthers not spurred. 



b. L. elliptic, minutely serrulate, scattered. 



3. V. gualtheriasfolium, Hook. f. Bhutan. Attains 8 ft. Berry blue-black ^J in. 

 diam. 4. V. glauco-album, Hook, f . Sikkim 9-10,000 ft. Bhutan. Bracts J-J in. long, 

 often persistent until the fr. ripens. 



c. L. entire. 



5. V. Dunalianum, Wight Ic. t. 1194. Sikkim 5-8,000 ft. Bhutan, Khasi hills, 

 Manipur. Yunnan. A shrub, of ten epiphytic. L. alternate almost distichous, lanceo- 

 late, long caudate-acuminate, blade 3-5, pet. J in. long. Bacemes in bud enclosed by 

 the broad imbricating, subsequently deciduous bracts at the base of peduncle. Fl. 

 pink, corolla ovoid-conic, £ in. long, anthers spurred. 6. V. ardisioides, Hook. f. Buby 

 Mines, Upper Burma. Hills east of Toungoo. Thaungyin, Tenasserim. L. sessile, 

 falsely whorled at the ends of branchlets, elliptic-lanceolate, racemes umbellate in the 

 axils of the uppermost 1. 7. V. arbutoides, Clarke. Patkoi range. L. scattered, 

 ovate, acuminate, blade 4-5, pet. stout, J in., sec. n. oblique, several pairs from near the 

 base, racemes hairy.
