256 ILLUSTRATIONS OF THE BOTANY OF [ Vaccinacee. 
Wall. Dr. Lindley has referred to Gaylussacia, and other species to Vaccinium, to which 
genus also certainly belongs Andromeda symplicifolia, Wall. 1522, from the Neelgherries. 
The Thibaudias are all found on the mountains of Silhet and Pundooa, as on Chirra- 
poonjee. From Silhet they extend to the coast of Tenasserim, where one species is 
found, and from that to Java, where there is also a species of Gaylussacia. Mr. Don 
has formed the Asiatic species into a new genus, Agapetes, from their ornamental nature. 
The stems and leaves of Vaccinacee are astringent and rich in tannin; the flowers. of 
many are highly ornamental, and the fruit of most acidulous. Those of Bilberries and 
Whortleberries (Vaccinium myrtillus, &c.) are well-known, as are those of Cranberries 
(Oxyceccus palustris and macrocarpum) : all would succeed well in the Himalayas. 
From the Honourable East-India Company’s collection of drawings formed under Dr. Wallich’s 
superintendence, I have been enabled to figure two very interesting plants belonging to this family, in 
Plate 79, but which, from my series having been previously completed, I have been unable to number ; 
though in binding, it may be put in its proper place between Plates 62 and 63. The two plants 
belonging to this group, first discovered in India, were referred by Dr. Roxburgh to the Peruvian genus 
Ceratostemma, but subsequently by Dr. Wallich to the South American genus T'hibaudia, as the Javan 
species have been by Dr. Blume. Though there is some uncertainty respecting one of Dr. Roxburgh’s 
original species, that represented in Plate 79, fig. 1, is certainly his Ceratostemma variegata, as marked 
- on the drawing, and agreeing upon the whole very well with the description, but not so well with the 
specimen Thibaudia variegata, No.'751 of the East-Indian Herbarium. But the drawing agrees also 
very well with the general appearance, leaves, inflorescence and corols of 7’. setigera, which differs 
however in having the peduncles ‘and calyx covered with sete, notwithstanding which Dr. Wallich 
asks if this species, Cat. No. 752, be 7’. variegate, var.? It is evident, therefore, that well acquainted 
as he must be with that species, he can have considered the possibility of 7’. setigera being a variety, 
only from its great resemblance to that plant; a point in which the drawing has been shewn fully to 
participate, as the flowers are tubular, somewhat ventricose, and contracted at the mouth; the 
filaments short, anthers included within the corols, extended into two long tubes, and the bases: only 
projecting a little (“ short appendages ” of Don), stigma5-lobed, ovary and berry 5-celled, many-secded. 
It appears that this species agrees in all essential points with Thibaudia, and in habit the species of 
that genus differ among themselves, especially with regard to the peculiar venation of some species ; 
and 7’. caulialata is described as having denticulated leaves (G. Don, Gen. Syst. III, p. 861). 
Dr. Roxburgh moreover describes the filaments as being sometimes slightly united at the base, and the 
anthers as united their whole length into a tube round the style. This is somewhat analogous to what 
has been observed by Dr. Lindley, in his new genus Cavendishia, belonging also to this family 
(Bot. Reg. No. 1791), named in honour of the Duke of Devonshire, one of the most munificent patrons 
of Horticulture. Three other species appear to belong to this genus; No. 752, 7". setigera, from 
Pundooa; No. 753, 7. vaccinacea, Cat. p- 235; verticillata, p. 22, from the same locality ; and No. 
754, T’. loranthiflora from Tavoy, on the coast of Tenasserim. Not having any of these species in my 
herbarium, and Mr. Don being absent from London, I referred to Dr. Lindley for his opinion on the 
subject, who, with his usual liberality, has dissected the flowers of the T'hibaudias in his possession, 
and agrees with me in retaining 7’. variegata in this genus; while some others, as 7’. Sprengelii, Cat. 
No. 6298, he refers to Vaccinium, and T’. serrata, No. 6298, to Gaylussacia. This is also represented at 
Plate 79, fig. 2, and though different from the plant named Thibaudia vaccinaeea, No. '153, which 
has smooth, laurel-like, subverticilled leaves, with setose peduncles and calyx: Dr. Wallich puts the 
query respecting this species “* an hee planta Ceratostemma vaccinacea, Roxb,” and it certainly agrees 
in many points with Dr. Roxburgh’s description ; but in Dr. Wallich’s drawing, the berries are represented 
as 10-celled, with apparently only one seed in each ; the corolla ventricose at the base and contracted at 
the mouth, and the stamens included within the limb; and, therefore, agreeing in all essential points 
with the character of Gaylussacia. ‘The whole of the species are well worthy the attention of any 
Botanist who has an opportunity of examining the flowers and fruit.
