ORCUIDEJE. 105 



longitudinal line. Aliont the mitldlo of the lip arc two prominent lumps or callosities 

 (one on each side of the line), of considerable size for that of the lip. The column 

 is long, slender, arched (almost hooked at the end) and -winged on the upper half. 

 Anther 2-celled. I'ollen-masses 8, long and tapering into caudieles, and cohering 

 in two bundles of 4 by their ghitinous extremities. The colour of the unopened buds 

 is greenish, that of the expanded flower char white with just a blush of rose at the 

 tips ; column rose ; anthers deep red ])urple. and the callvsities marked with red and 

 yellow. An extreme!}- elegant little Orchid sent me by Mr. Harding of Rangoon 

 in 1873. I named it accordingly after him. 1 believe he received it from Bhamo. 

 1 grew it for "2 years with the greatest ease at Maulmain in a pot, where tny one plant 

 increased to two or three. I should have liked to send it to England in a growing state, 

 but fearing that, if it were lost or died, tlicro would remain no proof of its existence 

 beyond a verbal record and a di-awing, I sacrificed it in its full beauty, forwarding 

 one dried specimen to Kew and n^serviug one for myself. The fortunate possession 

 of this perfect specimen has enabled me, now as I write, to re-examine the p<dlen- 

 niasses. In my original drawing, made in 1874. I represented them as attached to a 

 sort of gland, but 1 appended a note to the effect that I was not sure I was right, 

 tluit the ajipai'ent gland was torn, and I could not clearly make it out. This observa- 

 tion Prof. Keichenbach quotes in his descrii)tion of the plant ( Otia Butanicu, llambtirgh, 

 Fasc. I. p. 46), and suggests that the apparent gland had some irregular source. I now 

 find that the pollen-masses are without any gland, as is to bo expected in Hpidendretr, 

 but I perceive that the rostellum at the end of the column is very thin and mem- 

 branous, and I think it likely that in removing the pollen-masses from the anther, 

 an irregular fragment of this membrane may have been carried away with them, in 

 consequence of the verj- glutinous nature of the caudieles. 



The differences observable between this species and the description of the genus 

 are, that, though terrestrial, the pseudo-bulbs arc above ground, the petals are smaller 

 than the sepals, and the lip is undivided.

These two plants must be passed by with a brief notice. They both have 

 nndergi'ound bulbs of an in'egular shape, two long linear-lanceolate leaves and long 

 slender flower-stalks, which bear from 3 to 5 yellow flowers, about li inch across. 

 Sepals and petals broad, nearly the same size. The lip is 3-lobed or tripartite, and 

 in both is of a remarkable shape. Tliey are about a foot high, resemble each other 

 very much, differing in points of small detail. The first I find on Zing-gyik, near 

 Martaban, the last on the hills East of Amherst. It was also sent to me by the 

 late Capt. Gower, from Akvab. Thev are both easy of cultivation, and deserving 

 of it. 



Spathofllottix is nearly allied to liletia, from which (says Lindley) it is dis- 

 tinguished "by the middle segment of the ;5-pai-ted lip being unguiculatc with two 

 tubercles or "lamellae at its base, and by its two-celled anther." There is a hand- 

 some ])ui-ple Bletia grown now frequently in Rangoon gardens which I take to be an 

 introduction. 



Calaxtue, ii. Br. 

 Terrestrial or epiphytal plants, consisting of pseudo-bulbs which are nourished 

 by fibrous roots from their base. Flowers numerous in racemes on erect stems, wliich 

 spring from the base of the pseudo-bulb. Sepals and petals spr(>ading, nearly 

 equal, free. Lip connate with the column, entire or lobed, variously spurred. 

 Pollen-masses 8, in paii-s, tapering into caudieles, which adhere to each other by a 

 cobwebby substance, and are occasionally united by a spurious gland. Leaves 

 terminal on the ps(!udo-bulbs, broad, plicate. Species 3.

Pseudo-bulbs large, 4-5 inches, ovate, somewhat squared, partly clothed witli 

 membranous scales, of an ashy-grey colour. Leaves 2 or more from the end, a foot 

 or more long, 4 iuclies or more broad, lanceolate, ribbed, tapering downwiirds into
