ovate. Capsules ovate, bisulcate, glabrous. Humboldt, on the 

 authority of Zea, has joined this with Cinchona land/alia of 

 Mutis, with which it has not the least affinity. Called Asmonich 

 in Peru.

sae'nda Luculia, Hamilt. in D. 

 Don, prod. fl. nep. p. 139. A 

 small branching tree, with terete 

 pubescent branches ; elliptic, acu- 

 minated leaves, which are gla- 

 brous above and villous on the 

 veins beneath, on short petioles. 

 Cymes terminal, many-flowered. 

 Flowers rose-coloured, rather 

 fleshy, sweet-scented. Stipulas 

 solitary on each side, broad at 

 the base and cuspidate at the 

 apex, longer than the petioles. 

 Segments of calyx deciduous. 

 It is impossible to conceive any 

 thing more beautiful than this 

 tree, when covered with its nu- 

 merous cymes of pink-coloured very fragrant flowers. 



Very-grateful- scented Luculia. Fl. Aug. Sept. Clt. 1823. 

 Tree 16 to 20 feet. 



Cult. A very good rich light soil will suit this tree ; and 

 cuttings may be rooted in sand under a hand-glass, but with 

 great difficulty. 



XIV. HYMENODI'CTYON (from ^v, hymen, a mem- 

 brane, and IIKTVOV, dictyon, a net ; in reference to the seeds 

 being girded by a reticulated membrane). Wall, in Roxb. fl. ind.

LIN. SYST. Pentdndria, Monogynia. Calyx 5-toothed. Co- 

 rolla tubular, with a 5-cleft limb, which is plicate in aestivation. 

 Anthers linear, exserted. Stigma 2-lobed. Capsule 2-celled, 

 dehiscing at the cells, many-seeded ; valves ventricose, mem- 

 branous. Dissepiment complete. Seeds girded by a membra- 

 nous, reticulated border, which is bifid at the base. Trees, 

 natives of the East Indies, with compressed branches : coria- 

 ceous, petiolate leaves ; deciduous, glandularly ciliated Stipulas ; 

 and small, inconspicuous, greenish, pubescent flowers, disposed 

 in fascicles, the whole forming racemose panicles. Floral leaves 

 one under each branch of the panicle, lanceolate, convex, veiny, 

 on long petioles, similar to the large calycine teeth of Musee'nda, 

 but placed in a different situation. 



1 H. EXCE'LSUM (Wall, in Roxb. fl. ind. 2. p. 358.) leaves 

 oblong, downy : floral ones coloured and blistered ; Stipulas 

 cordate, serrated; panicles axillary and terminal; anthers 



almost sessile in the mouth of the tube ; partition of capsule 

 contrary. Pj . S. Native of the East Indies, in the mountainous 

 parts of the Circars, and chiefly of the valleys, where it grows 

 to be a large tree. It is called Bundaroo in the Telinga lan- 

 guage. Cinchona excelsa, Roxb. cor. 2. p. 3. t. 106. Tratt. 

 tab. t. 170. The lower pair, or two of the ramifications of the 

 panicle, are ornamented each with a pair of coloured floral 

 leaves. Panicles terminal, large. Flowers fascicled, small, 

 greenish white. The infusion of one fresh leaf in water all 

 night had little taste, but struck quickly a deep purplish blue 

 with a chalybeate. The two inner coats of the bark (the outer 

 light spongy stratum is tasteless) possess both the bitterness and 

 astringency of Peruvian bark, and when fresh in a stronger 

 degree ; the bitterness is not so quickly communicated to 

 the taste on chewing the bark, as that of the former, but is 

 much more durable, and chiefly about the upper part of the 

 fauces. The wood is firm, close-grained, of a pale mahogany 

 colour, and very useful for many pu'rposes. 



Tall Hymenodyction. Fl. July, Aug. Clt. 1820. Tree 30 

 to 50 feet. 



2 H. THYRSiFLo'nuM(Wall. in Roxb. fl. ind. 2. p. 151.) leaves 

 ovate, downy, pale beneath : the floral ones coloured and reti- 

 culated ; thyrse terminal and axillary, drooping ; stipulas ob- 

 long, fringed with coloured glands; limb of corolla urceolate ; 

 partition of capsule contrary. ^ S. Native of the East 

 Indies, in the interior parts of Bengal. Cinchona thyrsiflora, 

 Roxb. Branches forming a large ovate head to the tree. Leaves 

 from 2-8 or 10 inches long. Thyrse very dense. Flowers 

 small, greenish yellow, fascicled. The floral pair or two of 

 leaves are on longer petioles than the rest. 



Thyrse-Jlonered Hymenodyction. Fl. June, July. Clt. 1819. 

 Tree 20 to 30 feet. 



3 H. TLA'CCIDUM (Wall, in Roxb fl. ind. 2. p. 152.) leaves 

 ovate-elliptic, smooth, and shining above ; stipulas oblong-spa- 

 tulate, ciliated ; racemes ax'illary, slender, pendulous ; capsules 

 oblong. Jj . S. Native of the East Indies, on the north side 

 of Sheopore, towards the bottom ; and in the valley of Noakote. 

 Leaves from 6-10 inches long: having the margins slightly 

 waved. Common peduncle pubescent, bearing a hardly coloured, 

 lanceolate-oblong, pubescent, reticulated floral leaf, wnich is 

 convex on the upper side, and concave on the under. It comes 

 very near the preceding species, but differs, however, in having 

 broader, elliptic, downy leaves, and much thicker both terminal 

 and axillary subcompound racemes ; its capsules too are much 

 broader. 



Flaccid Hymenodyction. Tree 20 to 30 feet. 



4 H. OBOVA'TUM (Wall, in Roxb. fl. ind. 2. p. 153.) leaves 

 obovate, acuminated, smooth : floral ones lanceolate, acuminated, 

 reticulated, convex, glaucous ; stipulas ovate, acute, glandularly 

 ciliated ; racemes axillary and terminal, a little branched, erect. 

 J? . S. Native of the East Indies, and perhaps of Wynaad. 

 Young shoots green, much compressed. Rachis of peduncles 

 villous. At the apex of each peduncle there is a floral pallid 

 leaf, 2 inches long, convex and a little rugose above': glaucous 

 and concave, beautifully veined, and rather pubescent beneath.
