98. SGROPHULARIACEM. 



spathrilate or elliptic-ovate subobtuse and g^labrescent, uppex- oblong-- 

 lanceolate semiamplexicaul acute hairy. Flowers very slender white 

 or greenish-white, in terminal subpanicnlate racemes. Calyx •4-'5" 

 tubular 10-lined, with linear-lanceolate acuminate uneqiial lobes 

 about as long- as tube. Corolla salver-shaped with slender linear 

 tube slightly widened above, usually greenish-white, about 1"5" long 

 or three times length of calyx, lobes pure white within, spreading, 

 ovate, acute. Capsule ovate, glabrous, as long as the calyx, ■25". 

 Seeds minutely rugose. 



An occasional weed, introduced but not. I believe, cultivated. Fl. April-May. 

 Native of Mexico and the West Indies. 



4. N. alata, Link Sf Otto. Syn. N. affinis, nom. hort. 



A clammy glandular-pubescent herb about 2 ft. high with lower 

 leaves obovate to oblanceolate, obtuse or rounded, with the base 

 sessile and decurrent as wings on the stem, rarely some sub-petioled 

 through reduction of the lamina, upper smaller subamplexicaul often 

 oblong and acuminate. Flowers glandular-pubescent outside white, 

 pedicelled, in terminal bracteate or ebracteate simple racemes with 

 sometimes a few lower branches from the axils of the upper leaves. 

 Calyx 1", 10-ribbed with long-acuminate unequal lobes. Corolla- 

 tube slender, 3-3-5", slightly dilated above, greenish-white, limb 

 somewhat oblique spreading pure white, 2-3" diam. Capsule 

 oblong. 



Frequent in gardens. The flowers open in the evening and close next day and 

 are beautifully fragrant at night. Native of Brazil. 



FAM. 98. SCROPHULARIACE^. 



Usually herbs (always in our species), sometimes semi-parasitic 

 with opposite or whorled or alternate, often gland-dotted, simple 

 exstipulate leaves. Flowers always more or less zygomorphic, solitary 

 axillary or in simple or compound spikes or racemes or in axillary 

 cymes or composite inflorescences. Calyx persistent 4-5-merous, 

 valvate or variously imbricate in bud. Corolla sympetalous, 5-4- 

 merous medianly zygomorphic, rarely actinomorphic, lobes alternating 

 with the sepals, the upper two and lower three often respectively 

 forming lips, imbricate never plicate in bud. Stamens rarely 5 perfect, 

 usually 4, often didynamous, with the posterior rudimentary, or 

 sometimes only 2, anthers 2-1-celled. Disc hypogynous, annular or 

 unilateral. Ovary 2-celled with the cells median and placentation 

 central axile ; style simple or 2-lobed, stigma capitellate or on the 

 margin or upperside of the style-lobes, one of which may sometimes 

 be suppressed. Ovules manj-, rarely few, anatropous or amphitropous. 

 Fruit a capsule, very rarely baccate (never in our species). Seeds 

 usually numerous and small or fewer and larger, albuminous. Em- 

 bryo straight or slightly curved. 



The usuallj- accepted separation of the series Anfirrhiiwtdem from the 

 Jthinanthoidece by the only positive character of the posterior petals or corolla- 

 lobes being exterior in bud is most unsatisfactory and, 1 find, often misleading.
