sepals. Column short. Anther- cells close together, parallel ; pollinia 

 elliptic, somewhat compressed ; the caudicles twice as long as the 

 pollinia, thick, tapering to the broad ovate fleshy glands; glands covered 

 by membranous pouches ; staminodes small, rugulose, attached to the 

 outside of the anther-cells. Stigmas 2, conjoined to form a narrow 

 transverse band across the column between the anther-cells and their 

 pollinia, and separated from the cells by a large erect ovate subacute 

 tongue-like lamella.

The flowers are purple throughout. 



An extremely interesting species ; remarkable for the large erect 

 process interposed between the base of the anther-cells and the conjoined 

 stigmas. The long caudicles pass outside this process, and emerge 

 below the stigmatic surface where their glands are partially covered 

 by membranous flaps from the sides of the column. In Habenaria 

 secundiflora there is a resemblance to the structure here described in 

 the two erect processes which form flaps in front of the polliniar glands. 



Habenaria Massoniana, n. spec. Whole plant about a span in 

 height. Stem slender, with two or three blunt lax wide sheaths at 

 the base. Leaves 2 or 3, rising very near the base of the stem, narrowly 

 oblong-oblanceolate, acute or subacute, much narrowed to the sheath- 

 ing base ; length 2 to 4 inches, breadth '25 to *5 in. ; stem above the 

 leaves long, bearing at intervals 2 or 3 lanceolate acuminate bracts. 

 Raceme 1*5 to 3 in. long, sparsely-flowered. Flowers '45 in. wide at the 

 mouth ; floral bract linear, acuminate, half as long as the slender 

 shortly-stalked obscurely-beaked ovary. Sepals unequal ; the dorsal 

 broadly ovate or almost rotund, blunt ; the lateral pair ovate-lanceolate, 

 subacute. Petals linear, acute or subacute, about as long as the sepals. 

 Lip longer than the sepals and petals, 3-partite almost to the base ; the 

 middle lobe linear, straight ; the lateral lobes filiform, rather longer 

 than the middle lobe, curved and diverging, also de^urved ; spur rather 

 shorter than the ovary, slightly clavate towards the apex, very little 

 curved. Column blunt. Anther-cells parallel, close together. Stigmas 

 2, oblong-pyriform, diverging, situated under the mouth of the spur.

A species allied to R. viridiflora, R. Br., but that species has 

 smaller flowers, differently shaped leaves, narrower petals and a 

 longer more slender spur. It is also allied to H. Khasiana, Hook. fil. 

 (but is a larger plant with much broader leaves), and to H. ditricha, 

 Hook, fil., all members of the section Trimeroglossa. We have dedicated
