THE TASMANIAN FLORA. 189 



two lateral lobes bearing tufts of white hairs, the central lobe very short and 

 truncate, with 2 prominent truncated processes at the sides and a short papillose 

 centre. Anther reaching to the top of the column-wing or nearly so, prominent 

 above the stigma. 



Very common ; also throughout extra-tropical Australia. Fl. Nov. 



The two following are inserted here more for the convenience of reference 

 than out of respect to their claims to specific rank. 



2. T. AttiSTATA, Ziind. Same habit. Flowers usually paler, seldom spotted. 

 Central lobe of the column-wing developing into an over-arching, thin, entire, or 

 bifid hood ; lateral lobes as in the last, or rarely quite obsolete. Anther very 

 short, and nearly hidden behind the stigma and rostellum. T. angustifolia, H. ' 



Very cominon ; also extra-tropical Australia. Fl. Nov.' 



3. T. longifoJjIA, Forst. Similar to the last, only usually smaller, with a 

 narrower leaf and few flowers. The posterior lobe of the colura.n-wing long, 

 thick, and dark, over-arching the anther. T. nuda, H. 



Very common ; also extra-tropical Australia to New Zealand. Fl. Nov. 



intermediate forms between these three types are common in Southern 

 Tasmania. 



4. T. CTANEA, Lind. 8-12 inches. Leaf narrow, linear. Flowers few, blue or 

 white, usually veined with dark blue. Perianth-lobes about \ inch long. 

 Column- wing with a truncate-papillose pbsterior lobe and 2 subulate-lanceolate, 

 irregalar, lateral lobes. Anther raised some distance above the stigma, acute, 

 often bifid, protruding between the lateral lobes. 



Common in damp situations. Fl. Dec-Jan. 



5. T. VENOSA, It. Br. Very similar to the last, only more robust. Lateral 

 lobes of wing lanceolate, convolute, posterior-lobe obsolete or absent. Anther 

 much protruding. 



Common in numerous localities, in damp places ; also in New South Wales. 

 Fl. Dec-Jan. 



There has been much confusion in the published descriptions of these 

 two forms. The above apply to the pronounced types. Intermediate 

 forms are also met with. 



6. T. CAKNEA, R. Br. Stem slender, flexuose, 6-8 inches. Leaf solitary, 

 linear. Flowers few, pink. Perianth about ^ inch long. Column about 2 lines 

 long, the wing with a rather short, obtuse, central lobe, not over-arching the 

 anther, notched in the centre. Lateral lobes usually nearly capitate and 

 denticulate. Anther as long as the wing, and slightly protruding between the 



■ lateral lobes. 



Very common ; also South Australia, Victoria, and New South Wales. 

 Fl. Oct:-Dec. . 



Y&r. rohmta. Stem 1-1| foot, less flexuose. Perianth fleshy-pink, but 

 disposed to become blue in. parts. Lateral lobes developing fairly 

 copious ponicillate appendages. This is possibly a hybrid, as many 

 forms pass insensibly into T. ixioides and aristata. 



7. T. ANTENNIFEBA, H. Stem slender, flexuose, 6 inches to 1 foot." Leaf 

 solitary, narrow-linear. Flowers usually 1 or 2, yellow. Perianth about | inch 

 long. Column about 2 lines long, the wings without a posterior lobe, the lateral 

 lobes extended, spathulate, dark. Column ending in a broad, concave, thick, 

 pubescent appendage. 



George Town ; also Victoria, South Australia, and West Australia. PI. Dec. 



8. T. PLExaosA, Endl. Stems slender, flexuose, 6-12 inches. Leaf naiTOw- 

 linear. Flowers 1 or 2, yellow or white, about ^ inch long. Column nearly 2
